In this case it seems likely that it is a special order "OEM" version.  There
is probably a control microprocessor that is programmed slightly differntly
so that it returns the "fradulent" geometry information.  You might try to
compare the drive to a "normal" unit and see if there is a micro-processor
or ROM that has different part number/version identification on it.

It may not be that easy to get CDC to "fix" the unit.  In this case, you
might try patching the driver or playing games to force it to use the
"native" geometry...
