No, but my Hard Drive is on the A1200's internal SCSI which uses
Commodore's scsi.device.  The CDROM which I can't access under NetBSD
is on the 12-Gauge. I have had a few problems with the 12-Gauge SCSI
port, but have been blaming the NEC CDR-25 CDROM drive. It works ok
on the Amiga side. I have heard others complain about the CDR-25, but
maybe because I am unlucky (lucky?) enough not to have a second hard
drive, I have not experienced problems myself until I tried to use
the CDR with MS-DOS and NetBSD.

Judging by other replies to this thread, you might have the same
problem, only worse :-(
