I have 8 of the ProDrive Q80S from Quantum. The thing you are seeing is the
automatic thermal equalizing to compensate for the platter growth due to 
heat effects as it warms up. I have NEVER had a crash associated with it. 
Unless you are doing direct SWCSI calls the embedded controller should handle
this without problem. I run a large Mac BBS and run the death out of my drives
and have two that are repeatedly started and stopped. These are far and  away
the best drives I have ever owned and not one has failed todate. If you have
been playing (smile) with the jumpers on the SCSI board and inadvertantly
set up the drive for self testing the above may be incorrect. I actually ran
one of the drives set up this way for tow weeks continiously and it worked
the whole time...smile. It was noisy as H*ll and could not be reformatted but
it worked.
