The highest number that can fit into two bytes is $FFFF or 65535 blocks. Both the ProDOS 8 Technical Reference Manual and Beneath Apple ProDOS say the number is total blocks.It wouldn't be the first time that documentation was incorrect.True.I'd be very surprised if it were not just the maximum block number, or size-1. Of course, the programmers may have taken the buggy pathand left the last block out...Can anyone verify if a ProDOS volume is "full" at 65535 blocks used?Or can all 65536 be used?I have never actually tried to verify that, but I *have* verified that $118 is the number in the "total_blocks" field on a full 5.25" floppy volume. $118 is 280 blocks. 35 tracks x 8 blocks/track = 280 blocks. So it would seem the number in that field represents the total number of blocks exactly.snip <Charlie
Having heard that, I went and checked a few of my Microdrive CF cards using the Microdrive Utilities, and Mmmm-MMMM!, that crow is gooooood! I do partition them to 65535/$FFFF for ProDOS volumes. Sorry about that. And, the volume size in the partition table is, in fact, FFFF. 3^| Bill
