Thanks Barry. That is the answer I know I was hoping for, and that also 
answers Sean's original question too. We can delete images from the SDC via 
software.

I've been playing with the cmds.bas program from Darren via Allen's blog and 
it just hangs in an infinite loop on line 140 when I run it. I've tried it 
under HDB-DOS and RS-DOS, entering the various commands verbatim, but it 
never gets past that check loop. Clearly I'm doing something incorrectly. 
The SDC operates flawlessly on my system in all other respects.

I think I'll follow your suggestion of installing YA-DOS in the SDC. In 
addition to the SDC support, the partitioning features sound interesting. 
Though think I better do some backing up before I start experimenting.

Thanks for all the great info.  It is very much appreciated.
