MacBook Pro :: disk0s2: 0xe0030005 (undefined)
Posted on: 13th July 2008 by in MacOSXhis morning I put my macbook pro into sleep mode, packed it up, and left for work. Only to discover that it wont boot up again.
First Aid
Normal boot: does not work, as stated above.
PRAM reset (Cmd+Opt+P+R): does not produce any visible improvement.
Verbose mode (invoked by Cmd+v): the laptop boots in verbose mode, but immediately hangs repeating the same error message over and over:
disk0s2: 0xe0030005 (UNDEFINED).
disk0s2: 0xe0030005 (UNDEFINED).
disk0s2: 0xe0030005 (UNDEFINED).
disk0s2: 0xe0030005 (UNDEFINED).
disk0s2: 0xe0030005 (UNDEFINED).
disk0s2: 0xe0030005 (UNDEFINED).
It was clear to me that a problem with the hard-disk drive was at the root of all these issues: disk0s2 stands for BSD disk 0, partition 2.
The Ugly Single-User Mode
I turned off the mac, hit command + S, to get into single user mode. Ran fsck -fy
Result = Nothing changed.
Possible Solutions
- Diskwarrior
- Enter Single User Mode, copy my files to an external drive, replace the hard drive
Instructions can be found here.
Tune in next time, for the solution. (If one can be found)
Note: Its interesting to know that a good majority of users that are having this problem just recently installed the latest version of iTunes. *laughs* coincidence? I think not.

and who said that MAC got no errors and crashes?
your better off booting into single user or using a live darwin.bsd distro and copying your files over, then messing around with disk warrior.
Using diskwarrior right off the bat may mean you’ll loose everything.
Q8GEEK:
You do realize that “all” laptops regardless of brand use Hard Drives or SSD drives right?
And those components have nothing to do with the Operating System installed. So if a hard drive fails, that does not mean that OS is at fault.
A hard drive is susceptible to wear and tear, which is why most drives have a lifespan of 5 years or less.
My Laptop could have been running FreeBSD or any other “stable” OS with the same result.
But yeah end of the day, I still prefer Mac OSX over most OS’s.
no i’m just saying that for those who thinks that mac is superior because it doesn’t crash at all…
Q8Geek: well to be fair, Mac OSX Leopard does crash occasionally, but its soooo far and few in between that it happens. Still realistically speaking, Mac as an OS is still way ahead in terms of stability than Windows based devices will ever be in 5 years from now. Thats just the truth of it.
Windows does not play nice with limited resources, especially low drive space.
Also in Windows: Applications use DLL files, and often scatter their dependencies all over the hard drive. This is pretty chaotic and over time can introduce lots of problems.
Mac OSX appz are self contained, and do not rely on external dependencies such as dll files and what note. The only thing they write to the drive is preferences files in your home directory. Mostly harmless =)
I could go on forever about differences between Mac and Windows, but in the end Id say technically Mac OSX is superior. In addition to that “To each their own” =)
The end result:
All of this was caused by a bad block on the Hard Drive. There is only one way to fix this: Format -> Reinstall.
Sometimes it could be more serious than a bad block, and could be caused by actual physical damage to the hard drive.
Either way, once it happens Id recommend that you replace your hard drive as soon as you can, if you do not want to risk sudden data loss.
Im using the same drive for now, since I’ve backed up my data to an external drive, until Aramex deliver the replacement drive. (Which they lost)
