The 3M box is being misleading.  It's true that the disks technically hold
1.6Mb of information -- however, .4Mb of that is formatting information,
leaving you with 1.2Mb of free disk space.  In other words, these _are_
standard 1.2Mb diskettes.

(I found out about this when someone brought back a box of 3M "1.6Mb" disks
to a computer store I happened to be in at the time -- it turned out to not
be the disks at all, it was his fault for running format incorrectly.)

It is almost definitely not the disk's fault -- errors in 3M disks are rare.
I would guess "user error" in this case -- you, or someone else, did something
wrong.

One more (somewhat rare) possibility is that your disk drive's heads are
slightly out of alignment -- just far enough that disks formatted on another
computer are unreadable.  Your description of your problem isn't complete
enough to make an exact diagnosis...
