 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.


Hi James,

I suspected that it was something like this after reading through some of the
archives last night.  I almost sent still another note off to Heinz, but then
finally realized that the proper thing to do was to join this list.  :)  

I'll give it a try.  If it turns out that there is a change needed for them do
I post it here, or is dmraid still at the more or less DIY experimental stage?

If you see Quakeboy02 pimping for dmraid over on LinuxQuestions, that's me.  :)
