OK, so this is interesting. Since the CW was working using the test previously
I tried imaging the non-critical disks. None would read successfully. So, I
everything to the other machine with the better floppy controller and IMD
do much with them either using the “analyze” option. It read some tracks, but
and I got bored after about 30 tracks. They definitely are 512b sectors but the
lengths were crazy (G1=210 and G2=255).
Either these disks have not successfully survived over time, or something else
The system associated with these use a Tarbell DD controller which is based on
WD1793 controller chip. I did take one of the Seattle disks and tried to read
I got the same results. I also have Teledisk but the results are similar.
As far as the dates, only the Seattle-labeled disks have dates on them
disks above just have handwritten labels with no details.
At this point I think I really need to get the controller working so maybe I
can use an
alternative method to backup the disks.
