Re: //e disk density question

["Tom Zuchowski" <tjz@mindspring.com>]

All Apple II 5.25 drives use DS/DD floppies.  If the drives will work with
some disks but not others, than there is an excellent chance that the "bad"
disks are really and truly bad.  Magnetic media is NOT permanent but tends
to go random over time.  Those disks you have with no notch means that they
are write-protected and the data has never been refreshed on them from the
day they were made.  Also, many such disks use copy protection schemes that
made them marginally readable even when they were new.

FYI HD disks will not work in those drives, so don't even try.
