Promise RAID FastTrak TX2000 card.
4 Maxtor HDDs (1 is 100 and the other 3 are 133).
S.M.A.R.T. is enabled on everything.
Extra Cooling for all HDDs.
Virus scan runs daily.

I do have to synk the RAID once a week and defrag.

I have updated the BIOS on the ASUS P4T system board to 1006 but most of these problems were around before the BIOS update.

I will keep you posted....
