I have a couple of different models; mainly M2682s but also some M2684s, and
a single M2681. More info on the drives can be found here:

The drives need to be formatted for 256 byte sectors. More details here:

I've written a small program for the Beeb to format these drives to 256 byte
sectors and to write the FSM to the drives. I can also send this to you if
it's of any interest.
I got my most recent batch of drives last year from a UK ebay seller for
about ?4 a piece. I notice that there are currently no UK sellers, but there
are a couple of US sellers. Search ebay for Fujitsu m268*

This is also what you have to do with the Fujitsu drives.

You should just about manage that. In my full height drive case I have a
single 5.25" half height 40 / 80 track drive, and a 3.5" HDD - complete with
host adapter. Fitting two 3.5" HDDs with host adapter should be easier since
they take up a bit less space. The original PSU in my full height case was
not man enough to power my HDD. I replaced it with an ASTEC SA40 / LPT44 -
which is actually just about man enough to power 4 HDDs and host adapter.
These PSUs can be picked up fairly cheapy and work very well.
