6.2-stable power management

[J.D. Bronson]

Is there any way to verify ALL power management is disabled?
I have totally disabled it in my BIOS and I have
totally disabled it in the hard drives...

Yet I keep hearing a drive spin down and then immediately back up
over and over (at times).

If I install a different OS on this same machine, this does not 
happen..so I am thinking something within 6.2-stable is doing this?

any thoughts or ideas?
