Your disk may be on the way out.Important: before you attempt anything: make sure you have a backup!!!!And, here is something I found googling:http://hintsforums.macworld.com/showthread.php?t=134145 Helpful (1) Reply options Link to this post by RoadRunn3r,★Helpful RoadRunn3r Feb 12, 2012 10:01 AM in response to babowa Level 1 (0 points) Feb 12, 2012 10:01 AM in response to babowa Now I should hit Command+R on bootup or after?

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 http://apple.stackexchange.com/questions/104656/imac-startup-i-o-error-despite-successful-disk-repair 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 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.
