SCSI Pb or Help needed !!!

[gachot@bonnet.enet.dec.com ()]

	Hello,

	I have an Apple IIGS with an old SCSI Apple Card. I was using it
	with a hard drive 20 Meg, a friend of mine plug on it a 80 Meg
	without any problem.

	Now I have a 100 Meg HD with no system and no init.
	The SCSI card is in slot 6, in the control panel for slot 6 I have
	'My Card'.
	I plug the HD on the Card, I start the HD and then the IIGS.
	I boot from a 3"1/2 with the SCSI Driver Installed..
	During the boot when he arrived at the Prodos.FST, the system hang 
	and wait for ~3mnts and then continue.

	The problem is hat the HD is not recognized on the Finder and 
	I can't Initialized it.


	Could someone help me in as I don't understand what's happening. 

	could the problem come from a bad cable, I mean from the HD and the
	SCSI cable ???
