Notes I see on the copies.
For 2of7 first run I got:
 vcp copy dy0: dy2:
VCP - Beginning copy operation
VCP - *Diag* - I/O error on logical block 162., Status=-59
VCP - *Diag* - I/O error on logical block 183., Status=-4

Not good.
For a second run 2of72 I got:
$ vcp copy dy0: dy2:

Hm, not great.
Go back to a known floppy (7 of 7) and try it.

No errors. Floppy drive is ok.
