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 diskos2 io error mac 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. 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 ass

Hello! 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 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 http://www.mac-forums.com/showthread.php?t=20062 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. Jun 11 20:45:57 isunk kernel[0]: disk0s9: I/O error. Jun 11 20:46:38 isunk kernel[0]: disk0s9: I/O error. Jun 11 20:48:00 isunk kernel[0]: disk0s9: I/O error.

Naturally I got a bit panicky at this and decided to reboot off the install DVD and run disk utility... I ran all available first aid :doctor: procedures and the disk passed the tests. Nothing on my system has changed, no software or hardware changes have been made. Im totally confused b

After several reboots I managed to close most of my applications disk0s2 i/o error but the problem presisted. My free disk space is about 11GB. I opened “Spotlight” and saw the file indexing process in progress. After waiting for about half an hour I have decided to turn the indexing off, and did that through terminal. The slow performance persisted and when I opened the “Console”; I am getting PM kernel: disk0s2: I/O error Every second. As per Google search this is an HD problem. But how and why?
