21MB SCSI floptical drives and WHT SCSI card?


OLD CS1

Recommended Posts

I came across some 21MB SCSI floptical drives. They can also use 1.44MB floppies, which makes them a bit more interesting to me. Would these work with the WHT SCSI card?

 

My primary purpose is the 1.44MB capacity in the absence of a compatible floppy card. I have not been able to turn up 21MB media, and I think that would be inferior over-all compared to a 100MB SCSI Zip drive.

 

Along the same lines, how does the TI and the WHT SCSI handle removable drives?

I remember many years ago that this solution was used for Amiga computer.. On Amiga one people must used a hard disk tool for prepare the surface how a real hd and after change the number of sector.. in this situation for my idea your scsi drive with floppy must work. Try at example a look the command that your scsi card use for prepare the hard drive like sector, cilynder, etc etc

In Amiga computer was used a file configuration that after was "mounting"

Here one example

DH0:
FileSystem = l:fastfilesystem
Device = scsi.device
Unit = 0
Surfaces = 4
BlocksPerTrack = 38
LowCyl = 1
HighCyl = 822
GlobVec = -1
DosType = 0x444F5301

If I would make a guess, regarding SCSI at all, it could run.

 

Partitioning and formatting should be the same like on a fixed disk.

But maybe it all depends on the behave of the DSR, if ejecting the media (while system is running) ?

 

.....but please be informed that I am oblivious to this topic :D

That is a nice MountList to have handy. Thanks. I do have Amiga stuff, as well, so the unit could be useful there, as well or instead of.
