Here is a format.dat entry for the 2344:

# From: "Adam W. Feigin" <awf@iis.ee.ethz.ch>

# We recently decomissioned a couple of Alliant FX/80's which had these
# drives in them. Between for formatting program on the Alliant, and the
# Fujitsu manual, I came up with the following format.dat entry. We've been
# using this entry on the dozen or so drives we pulled from our Alliants
# for about 6 months now without any problems. The drive formats down to
# roughly 525MB with this entry....

disk_type = "Fujitsu M2344K" \
        : ctlr = XD7053 \
        : ncyl = 622 : acyl = 2 : pcyl = 624 : nhead = 27 : nsect = 64 \
        : rpm = 3600 : bpt = 40960 : bps = 600


Hopefully this helps. I can't find any info on the 2322. I have a 7053 
ESMD controller here. If it was possible to get high-capactity ESMD 
drives in 5.25" casings I'd definitely use them... All I have is a pair 
of Hitachi DK-815 'jet engine' ESMD drives. They are too large and too 
noisy to use though.

Regards,

Craig.
