I'd always believed that you cannot reformat DD discs in an HD drive, 
for the reason that the HD head is narrower than the DD, so won't be 
able to completely erase the (existing) data that may be there, which 
may interfere with reading in a DD drive.


That said, I've a number of HD floppies here that I have reformatted 
ADFS-E (800K) for use in the A3000, or even the ones in the FileStore.


Best wishes,

Rick.
