1.)	It could happen that the drive needs a reset from the ST 
		and is also blocking the disk drive, so it may	be the case 
		that you aren't able to save your work. (Perhaps this is a 
		problem with really old SH 204 Host Adaptors, [Claus Brod ????])

2.)	You shouldn't do that to your drive mechanism.
		

3.) Remove the metal-network covering the fan. 
		You should also buy voltage regulators (my english is catastrophal)
		type 7808 or 7809 and loop them into the fan supply.
		These chips lower the 12V power to 8/9 volts. 
		Be sure that the drive doesn't get too hot and that the fan
		always starts when you turn the drive on.
		
If you have further questions drop me a pmail but please keep
short, INCOMING mail must be paid to the .de backbone.


Greetings, Bjoern
