Hi Bob,
I ran into a similar problem with the same controller on certain older drives.
The problem has to do with the way the fasttrak bios sees the drive size and
geometry as opposed to the way linux sees it as reported by the old drive's
firmware. Normally the drive metadata sector is located on the last cylinder
of the drive, about 63 sectors before the end. Anyway you can probably get it
to work if you look through the data on your drive to find out what sector the
metadata is on, and then modify the dmraid source (pdc.c?) to add it to the
list of sector offsets from the end of the disk to try.

Dmraiders,
This was actually pretty easy to do. May I suggest the following change to
pdc.h? Seems like there should be some rhyme or reason for the offset, though.
Or is it just dependent on the model and revision of the controller? This is
a "hacked" Utra66 controller with BIOS V1.30.
OLD:
#define PDC_CONFIGOFFSETS 63,255,256,16,399,735
NEW:
#define PDC_CONFIGOFFSETS 63,255,256,16,399,735,675
Bob
Actually we have found yet another PDC location=991:
#define PDC_CONFIGOFFSETS 63,255,256,16,399,735,675,991
I think I have sent Heinz a patch for this, however it somehow got lost?
Anyway, thanks for the 675...
Woody, Xandros
