	Hmmm, interesting sounding rig you got there. Are you sure it's a 50 
pin connector for the HDD? Also, is it really a "full size" 3.5" hard 
drive and not a 2.5" laptop drive?
	IIRC, all laptop HDDs use a 44-pin connector for the IDE. 4 for power, 
and the other 40 for the data. You can easily get the appropriate 
adaptors to hook a laptop HDD onto a regular "full size" IDE connection. 
I've got one in my toolkit for data rescue purposes. Don't know if you 
could go the other way, though. The laptop might not crank out enough 
juice for the bigger drive.
	Wait a minute, just had a thought. Is there a separate connector for 
power to the HDD? If so, that 50 pin connector could be SCSI, couldn't it?
