Hi !
I have emailed the ATARAID maintainer about this but alas - no response.
I have a pdc20276 controller with a MBFastTrak133 "Lite" BIOS Version
2.00.0.20 (as reported on bootup). I have created a RAID0 array using
my primary master and secondary master drives. The other two are set
via RAID0 where only one drive is involved, because the stupid
controller wouldn't let me created another striped array consisting of
the primary slave and the secondary slave. However, I would like to use
software RAID (via mkraid/raidstart/raidstop) to create a RAID0 array.
Unfortunately, for some reason, Linux doesn't "see" one of the slave
drives, because under /dev/ataraid (with devfs on) I only have
/dev/ataraid/disc0 (which is the proper RAID0 consisting of the master
drives), and /dev/ataraid/disc1 (one of the slave drives).
Where is the other slave drive ? Shouldn't there be a /dev/ataraid/disc2
? dmesg doesn't seem to think so. Could it have something to do with
that star next to ID = 3 in the BIOS output (please see below) ?
Anyway, the relevant information follows:

Alternatively, is there some way to circumvent the BIOS and create a
proper ataraid-based RAID0 out of the two slave drives ?
