These WD-93048-AD drives are 5 head, from what
info I could find. Makes figuring out why only
20, 40, and 100MB drives work on it a very
difficult proposition.

I was thinking of upgrading the rom on my Vulcan controller card to
the last one available, and then partitioning a 128 meg cf card to
exactly 100 megs (5 partitions of exactly 20 megs each), leaving the
balance of the card un-partitioned, and then try and see if the
controller would see it.  Do you think that is worth a shot?


It shouldn't--I doubt that the Vulcan controller looks at any
information on the disk to determine capacity, just "geometry".
Partitioning is a logical operation, not a physical one.

It may be that the Vulcan firmware looks at the "model" string
to decide whether or not to support it...!


BTW...if anyone is interested in re-writing the firmware for the
controller, my offer still stands.  I am willing to pay several
hundred dollars for a re-written firmware that works for the Vulcan.
If interested, contact me off list to discuss this.


Cool--it'll be interesting to see if that ups its priority!  ;-)
