The FixDisk allegedly corrected some problem with the original Floppy Tape
Software, but didn't fix the date&time restoration problem.  I don't know
how you feel about it, but I prefer for the original dates and times to be
restored from tape.  The fix was simple: alter the scripts' tapecpio lines to
include an "m"

Deja vi? (Pun intended)  Thought I just posted something about tapes.  In
any event, the 3M DC600A are the preferred tapes and actually give you 620'
vs. the 600' with the Sony QD-600A tapes which also work fine in the drive.

Comparing the 550 oersted and 12,500 tpi ratings, it would appear the 3M
DC6150A tapes would also work, but these (generally) are more costly and
were designed for use with 150MB drives (still with 600' of tape).
