Heres an idea. Just get a 1-2GB fixed scsi drive off ebay and a scsi CD ROM burner and drop the Jazz drive. I have a 1 GB JAZZ drive here too but Ive never tried to get it working on my Ami 2000 as I went for a CD Rom burner. MakeCD for the Amiga is free now and CDs are less than 50c each.
Just an option :-)
