Or do you think I should try to rebuild the raid array with the bios > utility (maybe after some bios upgrade)? Or is this rather an udev problem? Likely, that volume_id needs a fix. I never really tested with a real ddf volume. What udev version are you running? Is this an Adaptec controller? Can you send me a copy of the sectors containing the ddf header? Along with the exact dd commandline you used to extract it, so can copy it to a drive and test it.
