Hard disk exerciser

I have a laptop that recently likes to shut itself off - for no appearant
reason. I suspect the hard drive may be the culprit because the sudden
power offs only seem to happen during disk access. I was wondering if
anyone knew of a program that will let me "exercise" the disk. Note:
there is no option in the BIOS to do this. Any info would be appreciated.
