Err... has the 5.25" floppy disk any hole/notch to indicate HD media?
The 3.5" surely has. I wonder what happens if I use "flippy" disks with
additional Write Protect notch and Index Holes punched in so I can use
the second site by "flipping" the floppy around. However, if the 5.25"
HD media has, my CoCo drives won't check it anyway, they are too old to
have heart of HD media.

OK, thanks, didn't remember exactly because I wrote so many BACKUP tools
20 years ago (might find my "CerCompCopy" in these days, guess what this
does... :-). Bill V., If you read this: I wrote this just for
educational purposes).

Do they have the same problem concerning sector 1? Or are they using a
"track read" and do the sector ripping by software?
