I don't seem to be able to find a way of decoupling those drives. The
card's firmware is MPT-BIOS-IM-5.07.02, which from the IM suggests that
it is the mirroring version, however

sd2 at scsibus2 target 0 lun 0: <LSILOGIC, RAID ARRAY    IS, 1000> disk fixed
sd2: 136 GB, 139712 cyl, 64 head, 32 sec, 512 bytes/sect x 286130176 sectors

is 2 x 73GB disks, so striped. I suppose it is possible that the disks
were set up by some Windows programme rather than that BIOS?

Have any of you had success with mpt(4) with such an array?
