I've got a 20" iMac with a 2.16 Ghz C2D processor, 2GB RAM and running Snow Leopard (10.6.7). I bought the computer new in late 2006. There is plenty of hard drive space left (196GB). The machine had no issues until last week.
Essentially last Friday I started experiencing a lot of hangups when using the machine. On a subsequent reboot, the dock completely disappeared and I could not recover it. Suspecting something became corrupted on the OS, I performed a simple erase on the Hard Disk, reinstalled the OS and restored my Time Machine backup. It seemed to resolve the problem.
A few days later, the symptoms returned. This time I repaired permissions and checked the hard disk, which came back okay. I also ran AppleJack with no success. It's not a user profile issue since the symptoms are evident on the new profile.
At this point I'm concluding the hard disk is going bad. Are there any tests I can run before I buy a new hard drive to install?
Thank you
Jesse
