Greetings!

Apparently this is a new beast on the world.

This item is advertised as a 234 Mbyte disk. Here is the format.dat
painfully extracted from ZZYZX (the distributor):

##############################################################################
disk_type = "Hewlett Packard C2233" \
        : ctlr = MD21 \
        : trks_zone = 2220 : atrks = 131 : asect = 0 \
        : ncyl = 1289 : acyl = 2 : pcyl = 1574 : nhead = 5 : nsect = 71 \
        : rpm = 3600 : bpt = 43056
#
partition = "Hewlett Packard C2233-ZZYZX" \
        : disk = "Hewlett Packard C2233" : ctlr = MD21 \
        : a = 0, 38340 : b = 108, 76680 : c = 0, 457595 : g = 324, 342575
##############################################################################

When questioned about the magnitude of the difference between NCYL and
PCYL, ZZYZX replied "That's what HP told us to use."

One gotcha to avoid: the manufacturer's original defect list on the
disk may run beyond NCYL. If it does (after reading in the original
defect list with DEFECT->ORIGINAL) delete those entries above NCYL;
otherwise the FORMAT may fail without explanation.

Thanks to the following for attempts to help:

        bb@math.ufl.edu
        nieusma@boulder.colorado.edu (Jeff Nieusma)

PS: would whoever maintains the format.dat FAQ please let me know that
    they have added the HP C2233 to their list? Thanks muchly!
