> Hi all!
> I'm currently writing some batch files on Windows to automate the process
> of building OS-9 disk images. I use toolshed's os9 command to copy the
> files on the disk images. The command works as expected except when I
> include the drive letter in absolute paths. Example:
> os9 format sq1-becker.dsk
> os9 copy Startup sq1-becker.dsk,Startup        <-- works
> os9 format sq1-becker.dsk
> os9 copy Startup c:\coco\sq1-becker.dsk,Startup        <-- fails with
> error 248: disk is filled to capacity
> Digging in the source code, I found out that when the path contains a
> colon, the disk is identified as a DECB disk without looking at the disk
> file content (step 2a in function _coco_identify_image in
> libcoco/libcocoopen.c). While it works well on Linux, it prevents using
> drive letters in paths on Windows.
> I compiled toolshed on my Windows machine with the latest source code. If
> I comment out step 2a in _coco_identify_image, the disk image is
> successfully identified as an OS9 disk and the command works as expected.
> My question is for the toolshed gurus: can this step be removed (at least
> for Windows) for identifying the disk/cassette image?
> Thanks,
