[QUOTE="sunk976, post: 122236"] [b]Update...[/b] I thought I would give an update of my situation now. I was worried about hardware faliure so I backed up all my files onto my server. Disk transfer was slow but I got it all off the disk. (this could be a useful tip for people worried about their hardware) I was advised to try the Apple hardware test found on the first disk that came with the Mac... place the disk in your drive and as your mac boots hold the option key (a.k.a the alt key) you can select to boot to a hardware test program that will run an extensive testing on your system... I was expecting my hard disk to fail the test, but it didnt. Infact every hardware test I have run has not found any fault with the disk... so now I am just confused. This morning I decided I would do a format and re-install of the whole lot, I made the installer write 0's to the entire disk, and it did so happily which again suggests that the disk may have been fine... I am not in the process of adding back all my software etc... so far the disk has not had one I/O faliure.. im still cautious of it though. The thing is my warranty runs out in about 10 days so if it is hardware I need to get it sorted.. I will post back again with any more findings as this might help someone else in future. [/QUOTE]
