This program may help salvaging data from a defective disk.
In many cases, the defect is in the main FAT area.
After running this program, TOS will use the spare copy of
the FAT (sectors 1-5) rather than the main copy (sectors 6-10),
when reading from drive A or B. After you copy the files off
the disk you should reboot.
After the (uuencoded) program: An updated version of 'scache':
this one avoids reinstalling itself in RAM if you run it again.
