Hi
I've been using 1.44M disk without much problems. I usually
format them several times. There is a disk surface test in the
ROMs that I've used a number of times. I expect that the drive
doesn't write as deeply into the surface and once the disk
is cleaned well enough, the 1.44M disk work OK. A bulk erase
would most likely be enough.
It is really suppose to use 720K disk but the drive is only
single sided.
I've fiddled in the Forth code with the disk. The disk is
a full 360K on the one side but the Cat only uses 256K
part of it since that is all that is needed for the editor.
One could hide special code or data in the unused parts.

Googles group for the Cat is canon-cat

DSDD floppy disks work fine, but I don't
believe that you can buy them anymore.
I think the Cat only uses 265K of disk space, and will format them if required.

We just had this conversation on the Ensoniq Mirage mailing lists.
There are plenty of places selling DSDD disks on eBay. The last lot I
bought appeared to be reasonably new (manufacturing dates on the carton
in this century), rather than NOS.
