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. -James 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.
