Hi,
I was running raid 5, kernel 2.4.0, ABit BP6 motherboard, 2 Celeron
processors, 4 IBM ATA disks. Unfortunately, the raidtab seems to have gone
missing.
After the mboard. failed, taking with it my Matrox display card, & Adaptec
SCSI. I replaced it with a ABit KT7A raid, with 800 Mhz. Duron, as this was
the only board available at short notice with 4 IDE ports.
These are the results I received:

I apologise for including so much material, in the hope that it may be
relevant.
Do I have any hope of recovering my data? The only option I can see in the
docs is mkraid --force, but this seems to be a do or die solution.
Thanks
