I take the SD card out and back it up on my Mac :) I haven’t gotten Drivewire set up yet, but it’s on the TO DO list.

When I did it manually from BASIC, I I would do this:

DRIVE 0,OFF — make 0 be a real floppy

DRIVE 1,”GAMES1.DSK”,NEW — make new disk image
BACKUP 0 TO 1
(switch disks)
DRIVE 1,”GAMES2.DSK”,NEW
BACKUP 0 TO 1

…except instead of using backup, I used a BASIC program to copy sectors. I was having disks with bad sectors that would abort BACKUP, so I wrote a program to copy as many tracks as I could.

For OS-9, the CoCoSDC command is not working currently, so I had no way to create and switch disks from OS-9. So, I wrote a simple BASIC09 program that would create .DSK files on the OS-9 side, so it was kind of like doing this:

OS9: mybackup /d0 os9games1.dsk
(switch disk)
OS9: mybackup /d0 os9games1.dsk

Then, I used the Toolshed utilities to pull those .dsk files off the CoCoSDC .dsk image. A dsk within a dsk!

If I had it to do all over again, I would do everything from OS-9, including the RS-DOS disks. That was my original plan years ago when I was going to write something like this for Drivewire.

I’m working on it.
