Can you please specify what parameters (logical= sector=20 > size, number of sectors per cluster) the partitions were generated wi= th? Atari GEMDOS and Atari partition programs always use 2 sectors per cluster. Since FAT16 can hold max 32k entries you can compute the rest of information from this (example: 63 MB partition needs 2 kB clusters to fit into 32k cluster limit so the logical sector size for 32-63 MB partition needs to be 1 kB). > Yup - did AHDI use particular values for logical sector size and sect= ors per=20 > cluster that we'd need to make sure will still work?=20 See above - 2 logical sectors in a cluster. That is actually the only difference from MS-DOS where they stick with fixed logical sector size and are adding more sectors to a cluster, IIRC.
