You might want to try idefix97 from Aminet. It helps with SCSI problems also. I was having similar problems as you on one of my A2000's and nothing I did seemed to help. Someone here on Amiga.org told me to try the idefix97 and I was thinking probably the same thing as you "I have a SCSI problem, not an ide problem". Well it took care of my SCSI problem and I was sold on the program. It's just an idea but it might work.
