I have connected a SyQuest 44Mb removable-cartridge drive (SCSI) to my 2000.
My system also includes:

   1. A2090 controller
   2. ST251 hard disk mounted internally (my main system disk)

The SyQuest works fine except for changing disks. If I remove a cartridge
and insert a new one, then enter diskchange <drive> on the cli, the
activity light on the SyQuest drive goes on and the system hangs (although
the mouse pointer still moves and some intuition operations still work).

This happens even if I reinsert the same disk. If I diskchange the same
disk without removing it, the system operates normally.

Each cartridge has a 1 cylinder old filesystem partition, and the rest
as a FFS partition. The problem also occured when I had them prepped and
formatted entirely with the old filesystem (1 partition).

Is there any obvious problem with what I'm doing? Can anyone offer me
any advice as to how to explore this situation?


Here are the mountlist entries for the first 2 cylinders and for
the FFS partition:

RES2:      Device = hddisk.device
           Unit   = 3
           Flags  = 0
           Surfaces  = 2
           BlocksPerTrack = 34
           Reserved = 2
           Interleave = 0
           LowCyl = 0  ;  HighCyl = 1
           Buffers = 1
           BufMemType = 0
