While using CiderPress to copy a volume made on a CFFA to a CF card
destined for a MicroDrive, I got an error. The CFFA volume was 65536
blocks and the MicroDrive volume is 65535 blocks. One block smaller,
so I couldn't copy the volume.

Is there a reason for this? Which is the correct size?

The max volume size for ProDOS is 0xffff blocks, so 65535 is correct.

May I suggest that ProDOS volume size 'is' 65536, because zero is a block. So, therefore, it would be $0000-$FFFF or $10000 or 65536. The partition Editor in the Microdrive warns you when you get to 65536 or $10000 by the "!!" after where it shows you the size you are making that partition. It's not an oversize warning, it is a MAX size warning. I make them that size all the time, and I never have a problem writing a CFFA partition over to a Microdrive partition. Bill
