sense errors..

hi all
some questions here.
I have multiple pe6800 boxes with the same disk configuration.
we are using linux md raid. each 73g drive is partitioned with boot, /, and
swap thats it.
md1 = /boot
md3 = /

I am getting multiple boxes with identical errors at boot time, but the
boxes all come up
and the raid sets are mounted etc.. I'd like to believe that these are
simple disk errors but
they are at same sector / block on the different servers .. this is a bit
odd to me. I guess
It could infact be a bad run of disks?? All the sense errors seem to be on
sd[a,b]3 which
would equate to the / partition.

Again I just want to bounce this problem off a few people framiliar with PE
hardware and
the linux kernel to make sure I don't replace all my disks  for  a non
issue.
