I did some testing:
First I zero'd the first 80 meg of the md device, then read it back and
compared, still all zero's. Then I rebooted and compared again, still
all zero's
Then I got 8MB of stuff from /dev/urandom, wrote it to a file then wrote
it to md device, read it back into a separate file, they still matched.
I rebooted and read it back for a third time, and they still matched.
I'm not sure if this means anything or not, but I was wondering if my
assertion of BIOS muckery still made sense
..
I haven't seen any evidence of it here, either,
so long as BIOS "JBOD volumes" are used.
So I don't have any explanation for your data "moving around"
when you switched drivers, unless *their* driver remaps things
at run-time.
Or were you switching drivers across those reboots (likely, I suppose)?
