Verbose mode shows a load of I/O errors. Disk Verify/Repair run via recovery partition completes successfully, as does fsck terminal command in single user startup mode (it modified the files on first run but not second). I reset the NVRAM too. However none of these have helped, same I/O errors afterwards. Thinking it might be due to OS files being corrupted I created a USB drive with installable version of OSX (actually 10.9 Mavericks), but it crashes during install. I wanted to try
How To Fix Disk0s2 Io Error
Apple Hardware Tools diagnostics but the startup shortcuts D or opt+D don't work - I read it's been removed so presumably I'll need to find a way to reinstall it first. I've tried the usual fixes such as safe mode (won't boot), removing all peripherals, even the RAM sticks. I can't hear the drive making any grinding sounds. Is there anything else I can try to fix this? Is it likely the HD has died even though Disk Repair is returning success? hard-drive imac boot startup install share|improve this question asked Oct 8 '13 at 14:46 Ben Wise 335324 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted Disk I/O errors literally translate to input / output errors, which occur when the system is unable to communicate properly with the hard drive. This is very indicative of a hardware failure, whether it be with the hard drive itself, the logic board or the SATA data cable that runs between the two. Given the age of your Mac (5~ years) I would assume that the hard drive is to blame. Disk Utility repairs the volume on the disk at a software level, often it will report when hard drives have a hardware failure but there are also times when it repairs correctly despite communication errors still being present. Apple Hardware Test (AHT) IS pretty good at giving you a solid answer but as you've found out it's no longer on your hard drive, likely lost during an old upgrade or re-ins

Im posting here out of desperation for some kind of help with my Powerbook. It is a problem that has only started to occur in http://www.mac-forums.com/showthread.php?t=20062 the last few days. The hard disk will begin to seek more aggressively causing itunes to skip and applications to halt. The colour wheel appears whilst the disk continues to seek and then all of a sudden it will go back to working correctly. The more applications running the more frequent the slow downs. I have been watching activity monitor whilst it occurs and none of the programs are using large amounts of processor time, infact the activity monitor itself is always on top with about 10%. Activity monitor does report large amounts of disk activity. I checked console and the system logs are reporting the following: Jun 11 20:23:13 isunk kernel[0]: disk0s9: I/O error.

His Macbook model is: MacBook (13-inch, Early 2008). His Macbook cannot boot. When the power button was pressed, the grey apple logo and the spinning thing appears. In addition, there is a progress bar underneath. I waited till the progress bar disappears, but it automatically shuts down after that. I tried to restart normally, but the same thing happened. I tried removing the battery and holding down the power button for 20 to 30 secs, but it did not work. I tried booting into the verbose mode, and "disk0s2: I/O error." appears. Here's a section of the log: Executing fsck_hfs (version diskdev_cmds-491.3~2) ** Checking Journaled HFS Plus volume ** Checking extents overflow file. disk 0s2:I/O error. disk 0s2:I/O error. disk 0s2:I/O error. disk 0s2:I/O error. disk 0s2:I/O error. disk 0s2:I/O error. disk 0s2:I/O error. ** Checking catalog file. ** Checking multi-linked f
