PFS copy protection

[bird@MCS.COM (J. L. Walters)]

I picked up a complete set of PFS manuals, disk and backup disk at a
sale. Recently I tried to boot a disk. Al went well for a time and
then the screen turned to trash and my disk drive continued to run
forever.

Being really smart I tried the same thing with the backup
disk. Naturally the same thing happened.

Looking over the battlefield I suddenly realized that I have three
position switches on my 5.25" drives that allow me to simulate:

1. Never write protected
2. Always write protected
3. Look at the notch.

As you might have guessed, the switch was in the "Never write
protection" position, which as I remember allowd PFS to write garbage
to the disk to destroying it since their disk had no notch so a disk
with a notch was "obviously" a pirate copy and subject to destruction.

My question, is thare a way to fix these disks?

Kind Regards,
