The thread listed below on MacWorld also points out this I/O issue : http://hints.macworld.com/article.php?story=20100929110958373 Earlier in the year I had a personal experience with the I/O errors on the internal hard drive in my Laptop. The first symptom of the problem was a lot of beach balling on Mac OS X. Then while performing a backup from my internal HD using rsync multiple I/O errors were reported. I tried to run the backup again. At this point the entire system crashed. I rebooted the system and it came up. At this point I figured that running fsck on the disk would be a good idea. I must have some file system corruption which is causing the issues. After all the S.M.A.R.T status on the disk was coming up clean and Disk Utility check was also coming up clean. I ran fsck it found multiple errors which I asked it to fix. However, when it tried to write the fixes back to the disk it failed, this resulted in a system that would no longer boot and a disk which would no longer mount. Initially, the only programs which were seeing the errors were rsync, fsck. I found that Tech Tool Deluxe (surface scan) would also spot problems on the drive even after performing multiple 7 multi-pass erases on the drive. Then about one month later a college of mine with the same model laptop and same model drive had exactly the same problem. The only tools for him which would report the problem with the disk were rsync and Tech Tool Deluxe. Disk Utility file system check came up clean as did the S.M.A.R.T status on the disk. In summary, if rsync is reporting I/O errors, then you may have a problem with your hardware. I strongly suggest investigating further. Before you start insure you have a backup of any important data on the suspect system or device! _______________________________________________ lbackup-discussion mailing list http://www.lbackup.org Change options or unsubscribe : http://lbackup.org/mailing_lists
