I cannot get diskcopy to work on any of my hard drive partitions. The
partitions I'm trying to diskcopy are the same size, and the same
filesystem, and have "Sys:System/DiskCopy" as the default tool in the
disk.info file, but here's what happens: 

diskcopy cd0: to cd2:
Place SOURCE disk ( FROM disk ) in drive CD0:
Place DESTINATION disk ( TO disk ) in drive CD2:
Press RETURN to continue
 writing 529, 259 to go
Error on DESTINATION disk
Unspecified error
Disk copy abandoned
Disk Copy Terminated

When I try it from the Workbench, the error message is "Disks are of
incompatible type and cannot be copied."

Diskcopy from floppy to RAD: works fine (but only from the CLI, dragging
one disk icon onto another in Workbench fails), but floppy to hard
drive, or RAD: to hard drive fails.

I've got an A2090A with a CDC Wren III SCSI drive on my 2000. I'm
running 1.3 KS/WB, plus ARP 1.3. I've tried both the AmigaDOS and ARP
MOUNT commands, and the AmigaDOS 1.2 and 1.3 DISKCOPY commands.

In case you're wondering, I'm attempting to use John Kjellman's (kjohn)
floppy-on-a-hard-drive trick for creating our user group's monthly disk
so I can work at hard drive speeds instead of floppy speeds. I've
created the hard floppy, but not being able to diskcopy really limits
it's usefulness.  (I was also trying to do a quick backup from one
partition to another, but I can live without that.)

It obviously worked for John, but he's got a CLtd controller.
Is there something in the A2090A that prevents a diskcopy?
Or do I need another diskcopy command?
Or something strange with the Control Data drive? (Format fails without
the 'quick' option, as I mentioned in a previous message.)

Thanks in advance for any help.
