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?

Miniguide to fixing Volume-Filesystem errors Apr 29, '11 07:30:00AM • Contributed by: santa97298 There are many drive/filesystem errors that can occur on a Mac. Here diskos2 io error mac are some common symptoms that are indicative of some of them: Not error 0xe00002ca able to boot the system: You tried to boot. Apple logo appeared, and wheel spun for about 15-20 disk0s2 i/o error invalid node structure seconds, then machine turned off. This repeated every time you tried to boot the system. (REASON: The system does not find your HD and thus the OS to boot). Everything https://discussions.apple.com/thread/3730727?tstart=0 seems to work fine till your system hangs briefly and in an unpredictable way. You wait for a while, and the system magically comes back to normal. But after another while, the same thing re-occurs! (This cycle repeats in the current session). You can do these simple things to check for other possible causes: Run Activity Monitor to see that http://hints.macworld.com/article.php?story=20110216112523818 this is NOT due to temporarily high CPU and/or Memory usage. Check the system log using Console.app or running tail -f /var/log/system.log in Terminal. If your system is having some I/O error then it is sure that there is an HD failure issue. I don't claim to be an expert on this subject matter, just an (over)enthusiast Mac user. This guide is purely based on my personal experience and is bound to contain errors. So, USE IT AT YOUR OWN RISK! [crarko adds: Consider this hint to also serve as a reminder to check your backups...]Possible problems: Your HD Volume/FileSystem is corrupted Verification: Use Disk Utility and run "verify" to check it. 2. Your HD is dying. Verification: Use Disk Utility and see the SMART status of your HD, although this isn't always reliable. Before making any repair of the disk, make sure that you have the latest backups. Repair might let loose the volume/filesystem info all together and then there will be no other choice than to recover the data by some data rescue s/w like

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 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.
