Hi,

I have acquired a non-Sun, second-hand Seagate disk labeled as ST39204LC
(9GB Cheetah 18XL). Both top labels and the appearance of the body, and
the circuit board, confirm, after a very careful examination of Seagate
documentation, that this is indeed the disk's identity.

However, after hot-plugging into an Ultra 450, the disk presents itself
as a 9GB Barracuda 9LP, and actually as:
<SEAGATE-ST39173N-3131 cyl 14382 alt 2 hd 3 sec 47>
Now, this is surely wrong, this is an SCA and not a 50-pin SCSI disk.
I am assuming someone has written wrong parameters to the disk.

Now my question(s): how can I bring the disk back to its true identity?
Format let's me set new parameters, but the variable number of sectors
per track confuses me. Can someone provide the correct format parameters
for an ST39204LC? I don't care about any data on the disk.

Thank you,
