My new MacBook Pro is acting more and more strangely. First it was random lockups, maybe once every few days, where the whole UI would freeze, even though the mouse pointer would still move. Now it’s frequent appearances of the spinning beach ball, locking up a single application and going away in a couple of seconds.
What’s more worrysome, I started noticing these kind of messages in the system.log:
May 3 15:56:19 MaBi kernel[0]: disk0s2: 0xe0030005 (UNDEFINED). May 3 15:57:07 MaBi kernel[0]: disk0s2: 0xe0030005 (UNDEFINED). May 3 15:57:54 MaBi kernel[0]: disk0s2: 0xe0030005 (UNDEFINED). May 3 15:58:42 MaBi kernel[0]: disk0s2: 0xe0030005 (UNDEFINED).
And finally, if I try to verify the disk using Disk Utility, the system will lock up in the manner described above. S.M.A.R.T. status is “Verified”, though.
I couldn’t find anything on Google regarding that error code, but I’m scared that my disk might be on the verge of abandoning me. I need to do a backup as soon as I get back home.
Yep, this is definitely a failing disk. Send it in or take it to an Apple store ASAP. My Sept. 2004 15″ Powerbook had a HDD fail, exact same symptoms.
Oh, and I had the lower RAM slot fail too, causing the motherboard to need to be replaced. Thank goodness for AppleCare
having the same problem with my macbook as well. I think it may be due to the extreme heat inside the case. I have, of course, installed BootCamp, resized several Parallels image files, etc on the drive, so it could be something else at work, but my money is on the heat.
I’ve been having trouble with my MBP too. This error is coming up just today when i try a command line single user boot after it was hanging on the grey boot screen
What happened with yours? Any luck fixing it?
I’m getting it as well. The MBP was just in for service. They replaced the battery, logic board and memory, but not the hard drive.
The following is showing up in system.log, and the computer beachballs at those same times. Even the clock seconds in the menu bar do not advance.

Yes, I have also been getting those errors. Im looking for somewhere to fix my MBP now.
I just got the problem with my MacBook. AGH!
Seeing same problem with MacBook Pro. Noticed while debugging an Active Directory / Directory Services problem. Have not seen any disk writing errors.
Testing shows that the condition on my MacBook Pro is triggered by a fault in Directory Services and does not *seem* to be hardware related. Right now accessing AD from my MBP grinds my system performance to a halt. Apps when launched, lock up. Rebooting clears the issue as long as my system does not access Active Directory. As soon as Active Directory is accessed, all is lost again.
Same here — got a couple of spurious crashes in the last few days… then dead, cold fish crash… tried booting a few times, nothing.. then one time got past the gray logo screen to the blue screen that appears just before the login window — let it sit there for an hour or more, then the login progress bar came up… then finally a login window… spent the last few hours doing a tar.gz archive of my home directory over airport to my other machine — a number of broken files… so probably time to get the drive replaced in this thing. Model is ST9100824AS …
Same here grrr….
Hello. Same problem here. Anybody has any news on that? I suspect a failing disk. However, I noticed that if I put my full home folder (80 gb) into the “privacy” list of spotlight, the computer becomes responsive again and the messages “kernel[0]: disk0s2: 0xe0030005 (UNDEFINED)” don’t appear in the system log any longer. Of course this is both compatible with either a software or a hardware failure, as spotlight keeps accessing the disk.
Anyhow: with the system booting normally (ie with spotlight on) the computer becomes extremely slow and I keep getting these messages in the system log. Any suggestions about the right course of action?
Cheers,
l.
I have been experiencing a similar problem and can’t seem to find any info. The system sometimes slows down extremely slow, presumably due to a disk error or controller error, and then it eventually requires me to do a hard reset with the 6 second power button.
When the system restarts, I sometimes get the little flashing folder icon with a question mark in it like it can’t find a disk. After about 5 hard power resets, the system eventually will get to boot and the problem will eventually magically clear itself. Sometimes the boot is very very slow after this problem occurs.
I too can do a fsck and see no errors, and the SMART status is verified. This is frustrating because there seems to be no pattern to when it will occur.
I do hear strange sounds from the hard disk when the problem is occurring, so I suspect its an issue with the hard disk. I don’t understand why Apple hasn’t recalled the MacBook Pro and replaced the hard disks. At work I’ve heard of people having a similar problem and having the hard disk replaced multiple times. It doesn’t seem to be an isolated problem, and I don’t believe it to be related to whether you let the hard disk spin-down or not, since I always wait for the hard disk to spin down before picking up the computer.
If anyone ever finds out exactly what causes this issue, please post what you find. The disk runs fine after the error clears, so it seems to be a hardware defect of some sort.
The only solution is to replace the hard drive.
Thats what I did. It works fine after that
I’ve had the hard drive replaced on my 15″ MBP for three times, after that I received a new machine whose HD failed after 2 weeks of use. Personnaly I suspect the SafeSleep functionality, or then it’s Parallels (running Oracle database within RHEL 4) that simply overheats and cooks the hard drives.
I am not running parallels so I am sure that is not an issue. I am sure its not SafeSleep because if it was, this would resulted in a more widespread complaints.
Another ’same here’, except I have a Mac Pro desktop. I guess I’ll try to get the drive replaced. I also noticed some other odd symptoms: Vuescan drastically reducing the dpi of scans after seeing one of these errors, the system incorrectly complaining about the startup disk being full. I’ll post what my results are after having the drive replaced.
Like Mikael, I had the hard drive replaced multiple times. After it failed with the 3rd hard drive, they replaced the machine with a brand new MBP. Two months later, that hard drive has also failed. All different manufacturers.
It feels like a design flaw. Our MacBook purchased this summer just after the original MBP has been absolutely flawless.
I just had the same problem today, but with a simple Macbook (not Pro). I’m not running Parallels or AD. I thought about doing it when, after the OSX update, at boot, I got a number of these:
Mar 15 09:22:50 localhost kextd[27]: kextd_watch_volumes: couldn’t set up diskarb sessions
Mar 15 09:22:50 localhost kextd[27]: diskarb isn’t ready yet; we’ll try again soon
I got my MB last summer from the USA. Does anyone know if this fault is covered by the basic warranty?
I just have the same problem to day. For some time the machine slowed down from time to time and to day, I turn it on and the screen remains gray (more than 1 h). It works well in target mode (and with windows !). In fact, yesterday, I had a problem with a file impossible to remove (error -36). I forced by replacing the file just before to turn off. A sector of an important file was probably clear :(.
After re-install of MacOS, all looks well (the machine is faster, it’s perfect :)).
I’ll see with the time if the problem is resolved.
Same problem here.
No Parallels.
MBP 2.16GHz Intel Core Duo with FUJITSU MHV2100BH Hard Disk.
Going to try an archive and install.
Disappointing…
Writing to you from a PC, my macbook pro has exactly the same problem. beachball and slooooooooooow. also very disappointed.
Same problem with a MacBook, daughter’s, mine has been fine. Applecare slow and generally inconsistent. Hard drives cheap and very easy to fit. Will just buy and fit one next time and save on th etravelling.
I also just encountered a similar problem with my MBP that I’ve had for about a month. It started as random lockups in different applications. The machine would freeze completely and the mouse would not move, I would then have to force shutdown with the power button. This kept occuring everytime I would use the machine, letting me work for about 10-15 min. I’m Sending the piece of crap back to apple tomorrow, so frustrating.
Switched “eagerly” to a MBP after years of Linux enthusiasm, after having criticized it for such a long time…thanks to our CEO, Gianugo, who gave me one…
Appreciated it for its look and feel, and for the ease of use, but I’m now getting, after only two/three weeks of development, the exact same error you describe, making development impossible.
My fears about MBP reliability are now coming to reality, what’s more when I’m supposed to deliver a project on Friday!!!
Getting back to my lovely VAIO, waiting for this crapbook to be repaired…
Well I had my MBP for like 11 months and just recently ive heard that the hd is makig an odd repeating clicking sound. So i pulled up system.log and oh my what a surprise…:
“kernel[0]: disk0s2: 0xe0030005 (UNDEFINED).”
But it only happens when I go to Runescape.com…It never freezes just sloooooows down considerably. Yet I am able to run almst all programs. Im thinking of completely archive and installing, but i hope i will not need to get a new HDD… That’s th reason i swiched to mac hopig that i would not even need a new HDD evry month…
If you have that spinning ball+total freeze problem, you probably have that 0xe0030005 problem.
If you have this problem, MAKE YOUR BACKUPS RIGHT NOW WHILE IT’S TIME, then immediately send your mac to Apple for a replacement.
This IS a failing disk : I know it because my disk IS failing RIGHT NOW : I had the problem of the freeze since the beginning but didnt know what it was… until that day when it refused to boot again…
Finally entered failsafe mode and saw alot of these 0xe0030005 errors… It means basically “I’m fucked up dude, don’t ask me to do that it f_cking hurts so much” : probably dead clusters.
I’m currently backuping to an external hard drive (with difficulty, under a console/failsafe) but some files (particularly big one) couldn’t be read anymore. Nothing too important tho.
TUTORIAL TO HELP YOU BACKUP IF MAC OS X DOESN’T RUN NO MORE :
- Plug an external hard drive
- Before booting, hold apple+s, then start your mac, to enter safe mode.
- DO NOT do a fsck : it might put your sytem in read only, which you don’t want.
- Under the console, type mkdir /Volumes/Backups
- Then, type mount_hfs /dev/yourexternaldrive (for me it was /dev/disk1s3 but for many it may be /dev/disk1s1) /Volumes/Backups
- Then, browse your internal drive with the command cd
- And copy the directories and file you want with the command : cp -R /directorytosave /Volumes/Backups
Once you saved what you could; delete anything too private if you’re paranoïd, then send your Mac to an Applecenter or to Applecare : because sooner or later, your hard drive will definitely die. It has one foot in the grave already.
Hope this helped.
Have to precise : type mount_hfs if your external hard drive is mac formatted. If it’s a Fat32 partition, then it’s mount -t vfat /dev/disk1s1 /Volumes/Backups
(disk1s1 or whatever : check in your /dev directory to see the name of your external drive by typing cd /dev then ls : most likely disk0 is your internal drive and disk1 your external drive : s123etc. relates to your partitions on those drives).
I had the same problem, they replaced a MBP for me at the beginning of the year , cause the hd failed 3 times. Now my company got me a new MBP and it’s happening again. How can we file a complaint with Apple????
Just had this same problem with my iMac this week. Suck. I don’t really want to reimage it/get a new drive. I tried running Disk Warrior on it and it told me if fixed things, but it still won’t boot.
Any other fsck like tools I can run on it just for kicks?
Well i had the sam e issue… Pissed me off but wanna hear something worse? Well i created a new admin account and stupily i installed a Guest OS emulator. (I still consider myself an idiot…) My cd drive is fryed (son is just uncontrollable..) and that account also got the same problem. So i created a third admin acount… Now when i get
“May 28 22:50:46 Blurry kernel[0]: disk0s2: 0xe0030005 (UNDEFINED).”
The app that causes it “unexpectedly” quit.
I stopped using that account and its all ove rhte dammed disk. Now when i run Shiira the dammed thing crashes… Cant wait till apple becomes wise and creates a system restore util for Tiger… Untill then, Im capitally SCREWED.
I’ve been having the disk0s2 errors as well. My MBP is a first rev model from June 2006. My hard drive has been replaced and it doesn’t fix the problem. A couple of tips for people when it does occur:
1. Let the machine cool down
2. If you can’t reboot normally, reboot in single-user mode (Cmd-S when you power on) and run “/sbin/fsck” -fy. It should fix disk errors. If it doesn’t fix them, run it again and again until it fixes them.
3. For backups, I find that the disk runs fine in target disk mode (i.e. hold down T when you boot and connect it via Firewire to another Mac). You need another Mac though.
Personally, I don’t think this is a disk problem. There is some other operating system or hardware issue that manifests itself as a disk error.
Note that I think the reason why backing up in target disk mode works so well is that you’re not writing to the drive, only reading. If you boot off the drive, it uses a section of your disk as swap space (i.e. virtual memory) so is always writing to the drive.
My MacBook’s HD died a month ago. And I mean dead, kaput. I was’t moving it about after closing the lid (SSM), and I wasn’t running Parallels at the time, just sitting at my desk working on a Word doc. Got the beach ball, then… got the ? folder on restart. System disks couldn’t see any hard drive etc. etc.
And now I find online forum after online forum full of people reporting the same thing. MacBooks have a SERIOUS hardware problem, but I don’t expect to get any satisfaction from Apple.
I just found this site after having the SAME PROBLEM! 3 HD failures on a MBP, then I got a new machine. 7 days later… HD FAILURE!
I have a question for those of you who have had a failure.
What size HD did you have? And how full was your HD when it started to fail?
I have had the 120GB version each time. And I have been about 80% full I think each time it has failed.
Maybe if we can find a common variable we can get toward the bottom of this, even if the solution is just that apple has made a POS.
Me too
MBP hangs peridiocally for several minutes with spinning beachball. 0xe0030005 error in the logs. Appears to recover after a while, but generally seems to be getting more frequent.
Yeah, I don’t know a whole lot about all of this but this MacBook was just issued to me a few hours ago with a clean 60G hard drive and now it won’t start just saying “disk0s2: 0xe0030005 (UNDEFINED)”. I guess I’ll take it right back to the help desk. I thought it was a smart choice because everyone said that PC’s broke right away but I guess so do macs.
my MacBook Pro core2Duo just did the same thing to me. 160gig drives was working great until 3 days ago, i ordered an extra drive for quick backup of all my files but they didnt arrive in time. my computer locked up unstuffing a file, so i had to force restart. the computer never whe past the grey screen after that. I had apple remove the drive for me (they are backup in work so could take it then an there to fix) and tried to boot the drive off an external enclosure but no luck at all. going tomorrow to get the computer fixed. - i did managed toisntall boot the computer off my external portable drive and the computer has been working fine this way. ive lost files and im very angry at myself (for not backing up sooner) and at this computer. i havent lost a drive since 1995. very very angry
My three week old MacBook Pro just had the same problem. Had the hard disk replaced under AppleCare. Will see if that fixes it…
My MBP just crashed its drive for the 3rd time since Feb/March. Can’t mount in target disk mode, can’t boot an external drive.
Was getting some spinning beach balls for a few days but didn’t think anything of it as I hadn’t actually seen anything suspicious in the system log or dmesg.
This is a repeating problem and I’m starting to get rather pissed off.
160GB HD in the first gen of core 2 duo MBP
Hi all
I have a problem, maybe someone can help me!
when i boot up my mbp it says:
localhost kextd[27]: kextd_watch_volumes: couldn’t set up diskarb sessions
windows is running like a dream with bootcamp but osx is running like crap!
can anyone help me!! i have heaps of important stuff on my osx partition!!

Hey gang, here is what I found with the disk0s2 errors. I was helping fix a friend’s Intel Mac Mini and found the disk0s2 errors in the system log. Looking like a hard drive problem I run the usual backups and disk checks. Then I found the error only occurred when Firefox was running. I renamed the FireFox profile folder in the ~/Library/Application Support/ folder and restarted Firefox. Firefox recreated the folder and no problems since. What I later found is that urlcassifier2.sqlite was corrupted and was causing all the problems. Hope this is helpful.
Wow! I thought Mac users never had to do any of this stuff. This sounds like a PC post from 5 years ago.
Is it possible the PC has finally caught up and surpassed Mac’s reliability? My two newer Dells running WinXP have never crashed on me and I am pretty much a power user.
Maybe now the only advantage Macs have is a friendlier, sleek interface?
I don’t mean to start a PC vs. Mac war, its just interesting to me as I’ve never seen so many Mac users having trouble, I mean there is 42 posters here all having the same problem!
Doubting Thomas, these are disk drive failures, and Macs and Dells use drives from the same manufacturers.
Toshiba makes a nice laptop.
Vista has been good too.
Archive and install? Does anyone have a quick how to?
I just woke up to this little gem on my iMac. Here’s to backups. And AppleCare.
I seem to be able to start my iMac in Firewire target mode, and mount it on another Mac in my house. I’m in the middle of using Carbon Copy Cloner to make a clone of the (failing?) drive before I decide to send the whole computer off to the service center.
I’m not completely convinced that it’s a hard drive failure though… I’ll try an archive and install next and, if I can boot after that, keep a close eye on it for a few days.
Like Guy Kawasaki, I’m an idiot. I fried the hard drive on my MacBook about four months ago and swore to myself I’d backup everyday. Well, last night I was working in front of the TV and wasn’t keeping track — the battery ran down and the MacBook went into sleep mode (or should I say “death” mode?)
Let it sit over night, tried to reboot this morning and got a flashing cursor and then localhost:/root# — went through all the various fsck -fs and PRAMs etc. Running from the install disk, I can “see” the drive — but it’s not repairable. At one point, running fsck, it said it was OK. But on reboot it went right back to the command line and not to the OS.
I have an appt to see the Genius Bar tomorrow AM — and I am hoping at the least that they can salvage a week’s worth of data (since last backup) before sending me to scurry off to buy a 3rd party internal replacement hard drive.
BUT — this is the second time. My last Mac was a 2000 PowerBook that lasted from March 2000 to early 2007 without a problem. I am reading about problems with MacBooks EVERYWHERE! What is going on? This is the first time I’ve ever considered going over to the “Dark Side”!
Here I am, back after an Archive and Install. Still harvesting a fresh crop of “kernel[0]: disk0s2: 0xe0030005 (UNDEFINED)” errors. SMART status, verified. No errors reported by disk utility.
Ah well – Leopard is here soon, might as well get a new hard drive and do a real clean install once Friday rolls around.
So… here’s the epilogue.
I made the decision to do the brain surgery on my Intel iMac by myself, for which I can thank my unwavering impatience. I’ve successfully disassembled and reassembled an iBook G3 four times so how hard could this be, right?
The new drive is now in there, working, and there are no more “kernel[0]: disk0s2: 0xe0030005 (UNDEFINED)” errors.
I took the old hard drive and put it in an external USB enclosure so that I could mine it for data. I got pretty much everything off.
This morning I woke up to hear the old drive sitting in the old enclosure: BUZZZZZZ. That was enough to convince me that this error really does act as a prelude to drive failure, and that I’d done the right thing. I felt vindicated, sort of.
I say sort of because, during the course of the surgery, I feel that I might have ruined my display. My 20″ Intel iMac, reassembled, seems to have a display that’s nice and bright on top, and ever so slightly darker as you move toward the bottom. I can’t tell if it was that way before, I’m imagining it, something’s not making contact properly inside, or I managed to physically damage the display. Fearing that I’d made a mistake plugging the backlight back into the inverter, I opened the iMac up once more to check the connections. Everything looked fine, and I still perceive the display as darker the lower you go. I don’t know what to do.
It’s been a bad computer week.
Well, I think I’m in the same boat as the rest of you. I’ve tried Disk Utility and even Disk Warrior, no luck. When I boot into Safe Mode I get this:
BSD root: disk0s2, major 14, minor 2
Load of /sbin/launced, errno2, trying /sbin/mach_init
Load of /sbin/launched failed, errno2
blah blah blah
probe booting in single user. .. do not match
WTF?
Same problem here, running on 10.5.1 (Leopard).
). Tomorrow I’ll try and boot it in target mode and see what happens when I try to access the file from firewire.
I’ve only got this disk for 3 months now (replaced the original 80GB disk with a ST9160821AS 160GB).
Last week I got the disk0s2 error for the first time. Today I downloaded a 50MB file, but whenever I tried opening it I got the same disk0s2 error + spinning ball.
These where also logged in a dmesg output (apart from the disk0s2: 0xe0030005 (UNDEFINED) msg:
[Level 3] [ReadUID 0] [Facility com.apple.system.fs] [ErrType IO] [ErrNo 5] [IOType Read] [PBlkNum 193642752] [LBlkNum 8450] [FSLogMsgID 1358390330] [FSLogMsgOrder First]

Disk verifies just fine (disk utility), fsck doesn’t get any errors, SMART status is verified.
I just hope this is an HDD problem (easy to replace) or corrupt installation problem (easy to reinstall) and not a controller/logic board problem, as i’d have to wait at least a month to get it fix (crap apple presence in my country
Thanks Joe for mentioning that Firefox was the culprit in producing the disk errors. I’m on an old TiBook, but was getting the same problem while running Firefox. Thought my hard drive was going kaput, but found your post, deleted ‘urlcassifier2.sqlite’ and everything seems to be working great again. No more disk churning lockups and errors, at least for now. Crossing my fingers.
I never imagined so many people would be going through the exact same problem.. too much coincidence for just a hdd failure problem in my opinion..
As for me, Apple support where I live is crappy too, so I’ve gotta do all the work here. Booting through Install CD and manually copying files via Terminal to flash drives (yep, no external hdd too..).
Ran Disk Utility a few times, and it found several errors, but it still managed to save some files by moving ‘em to the lost+found folder. What sucks is that part of my /bin folder was included in that, and now booting is not even an option. I’m considering reformating after I’m done backing up what’s left of my files, but I don’t know if that will be of any help. Has anyone tried a clean install to see if that solves? Or does the same problem occur after a while?
Hi what I done is when I install the boot camp 1.4 it work but when I finish partitioning my MBP I planned to install windows after work hour so I shut down my MBP then after i turn it on i lost 32gig of space in my hard drive and i cant get it back. pls……. help me i need my 32gig of space. Email me please rhyan.ablan@mcfzdubai.com
Wow. I just spent $2,700 bucks on a new MBP and it’s maybe three weeks old now… same problem. Mine started to freeze just today when I was using Safari. It started taking forever to load a page in my Airport Extreme G. Great signal strength so that wasn’t the problem. I then went to software update with Safari still open and it froze. Multiple attempts to restart gave me a grey screen… no beachball. Tried the C key multiple times with the original install disc and it finally recognized it. Dick Utility sees the HD but doesn’t offer any way to repair it… all options are ghosted. I thank my smart stars that I’ve been using an external Lacie FW800 for my presentation work or I would be totally screwed.
I’ve got a few files I would like to recover but not sure how to do it. I’ll try tech tool next.
I’m thinking of taking this overpriced piece of crap back for a refund. Brand new and hardly used. Oh, I also noticed a few days ago that while it was supposed to be asleep, it seemed very hot towards the left back.
jginn@tampabay.rr.com
Actually, it’s really hot all across the back. My tech tool as it turns out is pre-Intel so I’m trying a Disk Image in Disk Utility. It sees my external drive but gives me this error: “Input/output error”.
Oh Apple summit failure. The summit in stupidity. Now I understand why microsoft spread and spread. ? Because you are stupid Apple wants only money only money
I was having the same problem, and deleting urlclassifier2.sqlite did the trick. Can’t believe that one file could cause such system-wide trouble.
Did anyone else have success using that fix?
Help!
My hard drive just crashed yesterday and when I took the computer to Apple to see if they would fix it, they said they were unable to because there is a small grey splotch in the bottom left hand corner so they suspect water damage. 3 months ago, two drops of water got on the upper right hand corner of the screen and caused this splotch. Apple is saying that if I give it to them I will have to pay $755 flat rate to get a new LCD screen, new logic board and new hard drive. From what I hear from you guys, the hard drive problem keeps happening over and over for some people. Should I spend the $755 now or even get a new computer and renew my warranty or should I just purchase and install another hard drive myself and hope that it doesn’t happen again? I would think that if it does keep happening, it could become a very expensive problem. I just need a little advice, thanks!
I had this happen to me after an archive and install of Leopard. After I found this page, I was certain I was looking at a toasted HD. After a few reboots in the troubleshooting process, I finally noticed that the error only occurred when I had Safari open. After systematically moving Safari support files around, I finally fixed the problem by deleting ~/Library/Caches/com.apple.safari/Cache.db - odd, but I’ve not received this error since this file was rebuilt!
My MBP purchased in August 2007 (Santa Rosa) began showing a very serious slowdowns (JANUARY 2008), some applications have lost their icons and did not want to start. The log files informed on malformated files and the error code disks02 0xe (UNDEFINED) appeared several times. Apple Care had to replace the hard disk (160GB 7200trs)
To Jeremy Dickens: you are putting a bandaid on a festering wound. The UNDEFINED error suggests a physical problem on your hard drive — bad sectors, namely — and you are simply removing one file over where some of the bad sectors are. Make sure you back up because the problem is going to come back and only get worse until you replace the drive.
ive got the same error on a series of random files. Its now also on my parallels harddrive so i can throw that one away now. Its just a matter of time some important system file will also fail. Im contacting support now, hopefully i can change my harddrive for a new one.
I can verify that removing urlclassifier2.sqlite like Chad noted above from your Firefox library profile folder did the trick.
I’ve had word for word the exact same problem as Jeremy Dickens. This is the third time I’ve had this problem and solved it with a new hard drive. I’m not convinced that this is merely a hard drive issue, if 3 hard drives failed from the same computer…clearly there is something else wrong.
same thing for me.. i’ve been on 5 HDs on my first rev mbp (bought the day they came out)
this new one is a few months old. TIME FOR ANOTHER $200 SWAP OUT
I just got this on my macbook today (it’s less than 11mo old). It happened this morning when I opened itunes and the laptop slowed to a grinding halt. I did a hard reboot and it has never rebooted again into OS X.
Performed all the “fixes” mentioned here to no avail.
I highly doubt this is a hardware (read: bad hard drive) issue for me. My Vista partition on the same laptop works perfectly, no errors, no problems.
To the people that are complaining of having replaced multiple HD’s: Are you doing backup restores onto these new HDs? If this were a software issue, wouldn’t that explain the repetitive “bad HDs”?
Worst part is that I’m stuck in Peru for another month without my discs, spare hardware, and more importantly…an apple store.
I hate to double post but after doing a very tedious file copying in single-user mode I was able to save all of my vital info.
By the grace of Bit Torrent I was able to acquire a copy of leopard to reinstall OS X.
I am *VERY* skeptical that this error is strictly a hard drive failure error. I’m running 100% normal again with all my programs, settings, and files intact by just doing a basic reinstall.
