disk of Pascal programs because the OS could not find the right disk. The
error message was something like "Volume not found: directory erased".
UCSD Pascal's directory structure is absolutely elementary.
It's FAT has room for a fixed number of files, and each is stored
contiguously in logical blocks. If you've still got the disk,
you can easily recover your files. I'm not sure why it
would decide to zap the directory structure - are you sure it
wasn't your fault? :-) There's a volume label, and I thought
This was 10 years ago in high school. I doubt I can get back credit :)
the OS at least checked this before it assumed the
right disk
was in the drive - unless your program was working at a low
level, and asked for a specific (#4:, #5:) drive.
It was the OS itself that maimed my files. The OS! I put in the wrong
