which version of raid do you use? the 2.2.13 includes as i can remember
0.36 of raid and
on ftp://ftp.kernel.org/pub/linux/daemons/raid/alpha are only
0.90-patches for 2.2.11 which does not
apply to 2.2.13 :-(

i dont know :-( but i think, if the hardware recognize the badblock, the
error will be notified
and the driver will be informed, if it support this (some driver can,
other maybe not) what happens
if, the hardware does not realize the error ??? i dont know, because
raid1 give the read request to both
hdd's, and the faster give the data to you, if they are checked against,
i dont think so
