Re: Changes
Just a bit... Though where I worked around 1971, one of the operators reached behind himself to pick up a pack for a 2311 drive (6 platters, 7.25MB per pack) while standing on the freshly washed floor. He slipped and the pack came down edge on. The upside is that everyone had the presence of mind to *not* mount the (visibly bent) pack on the drive.
I was the one that had written the backup routines, so when I got in, I had to do the restore...to a different pack (obviously).
