Hardware Error

Hello,
I ran a hardware test on my 2008 IMAC, and received the following errors:

1st test: 4MOT/1?40000003:HDD-1346
2nd test: 4MOT/1?40000003:HDD-1348

any ideas on what is wrong?

my computer seems to be unable to handle simple tasks, yet activity monitor yields no significant memory use above 3-5%.

I read somewhere that this is a harddrive fan problem, but not sure myself.

Any help or advice would be appreciated.

Thanks!

It is a hard drive problem, but it could either be the computer confused about the fan, or the hard drive is legitimately dying and you need a new one. Check out this discussion from the apple website, hopefully it will answer some of your questions:
