Hi all,
Does anybody know much about the CMD HD?

It seems my Hawk Seagate 2 gig mechanism crashed, this mechanism had always
run fairly quiet but within this year it has gradually been running louder,
until just last week it will not longer bootup.
The top green Activity light comes on and blinks for an eternity then goes
out
then the Red Error light flashes.
I have my CMD HD device number set at 8
I have my UIEC2CF set right now at 9
I used Jiffy-Dos to cycle to Device 8 but on the monitor it didnt show 8 it
displayed 30  but the CMD HD doesnt complete its boot, I cannot access
anything on it, not even pulling up a directory.  :(  Yes the mechanism
spins up but thats it, just errors, nothing.

I have one other Hawk Seagate but its the type that has jumpers on the side
of the mechanisms controller board they are labeled as:

TE DS ME WP PE SS TP TP
Do any of these jumpers need to be jumpered?  If so could someone provide
me with a good physical layout of how the jumpers are placed, please. I
would rather have a graphical layout  and ascii diagram wont do.

So if this mech wont work I have heard that there is some kind of
SD remake for SCSI, would this possibly work in the CMD HD?
If so no more noisy mechanical mechanisms to listen to that would be
really nice, the CMD HD only recognizes up to 4 gig, I think its something
to do with the boot Rom only supports up to 4 gig.

Thank you,

Terry Raymond
