I have a BMS200 board, and my ST doesn't work at all if the hd is plugged in
the DMA port but not powered on.  The people at BMS warned me against using
the ST without turning on the hd, due to some sort of signal "float" problems.
If you want to play games without the noise, unplug your hd from the DMA port.

As for noise, I have no idea if this pertains to Supra drives or not, but some
drives have a little "static tab" that sits on the end of the drive motor
spindle.  This tab can wear out and make a shrill loud noise.  Maybe that's
your problem?
