Another possibility (and one that I encountered a few years ago) is
that your emulator "adapts" to DOS-order or ProDOS-order disk images,
but the process of converting to a real disk does not.

It would be interesting to look at one of the non-working disks with
a sector editor to see if things are where they are supposed to be.
