Just asking: do you have
gvpscsi.device or a later version entered into the
Tooltypes of HDToolBox and Mounter?
My HDToolBox uses the VALUE NAME of
SCSI_DEVICE_NAME=, and the version of Mounter I'm using for GVP uses the VALUE NAME of
DEVICE=.
Some SCSI Controllers own Partitioning Apps
may work better than HDToolBox with their own SCSI Standards. With my GVP ones with original ROMs I've used
FaaastPrep, and I use
scsiconfig3 with my Blizzard 2060.
As to
Mounter, my own scanning my Blizzard 2060 Controller is shown....

As can be seen, both
Removable Media and unused IDs show the same
Status when no removable Disk/c is present.
In similar fashion,
Media shows the same result for
Fixed Media as for unused IDs.
