The best answers are voted up and rise to the top Apple infinite load. I/O error and even a new HD up vote 0 down vote favorite My mac mini from the 2011 refused to boot. Apple logo and loading image forever.. I tried cmd+s: Went through all the steps from the applejack, tried fsck -fy, all semmed pok, Tried cmd+v: It wouldn't fully load, got disk0s2 i/o error mac the error Disk02 I/O error (it was the original 1TB disk with two partitions), So I thought the HD must be done, so I bought one Samsung SSD HD 120GB Sata 3, Same result. Thing is that I tried with both drives to install again the mac os x vía USB (I don't have a CD drive) and in both cases I came up with the tipical 'you must reboot your computer' error scereen. So With the new HD replacing I did same steps, cmd+s and cmd+v provided same results....

Then I would try an SMC reset. Mavericks and Mountain Lion can be pretty finicky and even strange when new hardware is installed. I've had to reset the SMC on my system with Mavericks 3 times since I started using Mavericks. In my case, it's Mavericks, not the hardware. It's bu

Compact Level 1 (0 points) Q: CoreStorageGroup::completeIORequest - error 0xe00002ca I've just had a couple of frustrating days tackling some annoying how to fix disk0s2 i o error symptoms so I thought I'd provide a fix here for anyone else Googling the imac i/o error same error messages.I'm on OS X Lion 10.7.2, using Filevault 2 on a 2011 17" Macbook Pro (8GB RAM with the skype disk i/o error mac stock 750GB Toshiba MK7559GSXF drive). I upgraded from Snow Leopard to Lion on my old 15" 2008 MBP and then recently migrated to the 2011 MBP using Time Machine (i.e. there was several years worth http://apple.stackexchange.com/questions/127172/apple-infinite-load-i-o-error-and-even-a-new-hd of junk lying around pre-Lion and pre-2011 MBP). OS X is up to date, even the new EFI update this week.The symptoms were:1) Beachball every few minutes - all applications would stop and hang for between 10 and 20 seconds. Some applications seemed more prone to triggering the problem but I think it was coincidence. The mouse cursor moved but everything else stopped.2) The following errors appeared in the kernel log https://discussions.apple.com/thread/3444529?tstart=0 and console after the beachball event:kernel: CoreStorageGroup::completeIORequest - error 0xe00002ca detected for LVG "Macintosh HD" (EE74B25C-0D2C-49B5-BF7D-EFF4D0D4EA18), pv F035EDD4-32D0-4718-B83B-2D61C774E567, near LV byte offset = 320161787904.kernel: disk1: I/O error.Note that the CoreStorageGroup error contains a drive label, after a while I realised that my disk wasn't even called 'Macintosh HD' so an unknown application was trying to access an unknown file on a drive that didn't exist. I checked my drive ID using Macpilot and it wasn't the same as the one in the error (EE74B25C etc). 3) There were no other error messages around these messages that pointed to a specific application.4) All disk checks reported no problems at all. Disk Utility (both from within my user account and from the Lion install disk) and fsck from single user mode were happy.I was bracing myself for a reinstall but then I worked through some tidying up and one of these fixed the problem:1) Went through ~/Library/Preferences and deleted some files and folders with corrupt names. I also deleted some old .plist files while I was there.2) I thought Spotlight might be a problem (maybe an old index entry expects to see a file on 'Macintosh HD' when my drive is really called something else) so I ran 'sudo mdutil -E /'

If you've replaced the drive, even if you haven't, I would reformat the drive and use the option "write zeros". This will map out any bad blocks on the hard drive. A bad block will cause your system not to work sometimes when part of the system gets written to it. As a matter of course now, I zero out every hard drive I get, especially brand new ones. These hard drives are made as cheaply as possible and quality controls allows certain percentages of drives to be defective. So do your own quality control and you won't have to worry about this potentially devastating problem. Was this answer helpful?

It boots most of the time with random question mark folder errors. But when I boot into OS X the computer locks up every few minutes and I get I/O errors in the Console. I have tried a total of 3 known working drives all with the same results. 08/05/2011 by Grant If you're lucky it may be the hard drive cable, check your logic board conne
