If anyone wants 3.5" DSDD disks from me, I'm all out. That lot that I
posted about last week is mostly bad judging from the sixty I've gone
through so far. With 200 to go, I'll just chuck this mess out unless
someone here wants to do something silly like make a suit of armour out of
floppies. If that's the case, I'll sell the whole lot for the cost of
shipping.

Q: Why is top-posting such a bad thing?

How does an entire lot go bad? Are you seeing an exorbitant amount of
bad sectors after a format?

Double-sided, 80 tracks, 9 sec/track. Total capacity 720 kB.
Formatting ... done

These disks were found in a box, not protected very well from dust. That
might have done it.

have you got other DD disks from a different batch / system that format OK
with that drive? Or a different drive you can try to rule out any problem with
the existing one?

It could also be the same situation as the large box of 3.5" DS2D diskettes
that we have--they were rejects accumulated over a few years of
duplication. They're unlikely to get much better.
Cheers,
