I have an Applied Engineering AE Vulcan 40MB in a //gs ROM 1. I know the hard drive will not last forever, so I wish to make a backup image of it.
As a test, I have removed the hard drive temporarily and in its place put an IDE to CF adapter with a 32MB CF card. I have booted from the Vulcan floppy and run Partition Manager, and created a 20MB partition and a 12MB partition on the CF card. Then I copied all of the Vulcan floppy files to the new partition, and then created a folder and copied all of ADTPro 2.0.3 into it. Finally I created another folder and copied all of COPY][PLUS 7.4 into it.
I used Apple Commander to create a new Virtual.po volume, and then after putting that file in the appropriate directory on my Raspberry Pi, I started up ADTPro, after first connecting the USB -> //gs modem port via a null modem cable of course.
I also copied the ADTPro Virtual Drive programs into the Vulcan CF "hard drive" ADTPRO folder, and ran the VSDRIVE program.
All that is the setup to the issue:
ISSUE: When I copy files from the Vulcan to the Virtual Drive, I always get an error code $7C, and the copy fails.
I really would like to back up the original Vulcan physical hard drive, without 2 dozen 800k 3.5 floppies. :-)
Anyone have ideas what a $7C is? I've googled and read both ProDOS and Copy][Plus error codes... it is not listed that I can find.
