Here's how to make a disk image from a ProDOS volume in Mac OS X which
ADFS can open:
Connect or insert the disk. The system will complain that it can't read
it. Click ignore.
Start Disk Utility in the /Applications/Utilities folder. The disk will
be shown in the side bar even if it wasn't mounted.
If the disk uses an Apple partition map (e.g. CD-ROM or SCSI hard drive)
the partitions will be shown under it. Select the partition you want.
Since Disk Utility doesn't recognise ProDOS volumes it will probably be
called something like '32.0 MB Untitled 0'.
If there is no Apple partition map (e.g. CFFA card) you will have to
image the entire disk.
Click 'New Image' on the tool bar. Select a name and location for the
disk image. The image format may default to compressed. Change it from
the pop-up menu to DVD/CD master. This is a simple raw image format with
no headers on it.
Click save.
If you imaged the entire disk and there was more than one volume on it (
e.g. four 32 MB volumes on a 128 MB card) then only the first volume
will be recognised by most Apple II emulators or disk image utilities.
If you know exactly how big each volume is you could use the command
line program 'dd' to split the large disk image into seperate images.
One more step is required for ADFS. It seems ADFS ignores the filename
extension and will only open a disk image if it recognises the HFS file
type code. I used Quick Change http://www.everydaysoftware.net/
quickchange/ to set the file type code to 'hdrv' and the creator code to
'pdos'. These are the codes ADFS uses when it creates a raw hard drive
image and once they were set it happily opened the images I made.
