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 http://www.mac-forums.com/showthread.php?t=20062 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.

At first I thought it was caused by a faulty hard drive, but now I've replaced it and I still get those errors. These are the steps I have followed beginning from the first time I noticed something was wrong: Laptop hangs with just Google Chrome and Postbox (an e-mail application) I restart the laptop, but it never gets past the screen with the grey apple. Started Apple Hardware disk0s2 i/o error Test by holding "D" during startup. This came up with no errors Through Verbose mode, and Disk Utility of the install CD I saw that it had disk I/O errors. I switched the Momentus XT drive for the stock Apple HDD. Installed a fresh copy of Snow Leopard Recovered everything from a Time Machine backup After a day it started giving disk I/O errors again in Console. This makes me think that an app or a setting is causing this as it is unlikely that both the hard drives are corrupted. How can I pinpoint which application is the cause? Below are my system details: MacBook Pro 5,3 2.66 Ghz / 8GB RAM Snow Leopard 10.6.8 First HDD: Seagate Momentus XT 500GB Second HDD: Stock Apple Hitachi 320GB macbook mac hard-drive hardware share|improve this question edited Jan 7 '13 at 15:59 bmike♦ 116k38202443 asked Jan 7 '13 at 15:54 Saaru Lindestøkke 2,03032348 If you are not equipped like a repair shop with ample spares and ability to isolate failures by systematically testing each component in the chain, I would re-seat the cables (or the drive if you are not comfortable getting to the cable interface to the logic board). IO errors are almost always a failing drive so swapping that drive once the error rate (or loss of time or data) outweighs the cost of the time and parts to repair that drive. –bmikeϗ
