How do I check my HDs for problems?

I need to check my HDs ( 2 x 36GB Raptors in RIAD 0)
I got a BSD and am thinking one of Raptors may be the culprit
I cant seem to get into DOS and run the WD Disk Diagostic Utiliies.
I keep getting " Cannot Load DOS!" error message.

Have you tried booting off the manufacturer's cd and running their diagnostics? It wasnt too clear from your post.
You can also run manufacturer diagnostics from within windows, although if the raptors are your OS drive, I'm not sure that will work.

Well....I was able to get into the WD Disk utilities and did a disk scan with no errors.
Still cant understand the BSD and screen freeze.
CPU or Video?
