Yes, the Focus expects its own structure for the partition table - so
some software will need to be built from whole cloth to do that work on
any other platform. The only one that exists to my knowledge is a
little graphical app on the GS. There's no partitioning code in the
firmware.

I had 2 focus drives back in the day and I don't remember that graphical app, but I must of used it since I had a 287 Mb with 9 partitions and a 340 Mb with 12 partitions. I have also seen a website removing the little drives that were attached to the card and connecting the card to a 1 Gb IDE drive.
Dos SOS have the same restrictions for number of volumes mounted as Prodos (14)?

I've only ever seen a max of 8 DIBs per device driver; if you had 4
cards and filled them all with 8 volumes each, you'd get 64 online at
once. I don't know that there's any limit besides that. I have enough
CFFA3000 cards to test the theory... might make a fun experiment one day.

Alltech would sell them pre-formatted for IIe users.

I have mine connected to a 128MB CompactFlash card with IDE-CF adapter. Both
card and adapter were very inexpensive.

And it probably had a partition size of (one or more at) 32MB. Packages
such as Business BASIC and the System Utilities will get confused when
partitions get above 16MB (they used signed integers for number of
blocks; 1 block = 512b). So it is always best to feed a /// partition
sizes of 32767 blocks or fewer.
