SCSI *IS* a pain if you're not used to them. Are you trying to use the same drive with all those cards? If so, make sure it is terminated properly and that you change your device driver to its appropriate designation. In other words, make sure HDTools (or whatever) knows you've got a SCSI card named xxxxxxxSCSI.device (usually has the card or brand name and then the SCSI trailer).
In the early days, Amiga used to be known for its seemingly "plug and play" attributes. Yeah, right. You've got to take your sally by the hand and tell her EXACTLY what is going on, else things do not work right.
