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.
