hi list,

i have a 2.0.1-RELEASE system running on a dual PIII machine (IBM 
Intellistation which features ECC, might be important?) configured to 
run a RAIDframe RAID1.

this is the only x86 machine i have, all others are non-x86; i have a 
few Sun Ultra 1E and Ultra 2E running in a similar config (also RAID1) 
which do not show this or a similar problem.

yesterday i tested the RAID config by fiddling around and making one of 
the HDs unavailable to the system. all went okay.

so i had to rebuild the parity of the RAID set -- so far, so good. out 
of a curiosity, i enabled SMART on the HDs (which are both of this type 
[1]) to check the drives' temperature(s)...

i saw following entry on wd1 while rebuilding the RAID:

(...)
195 100    0     no  online  positive    Hardware ECC Recovered         
6171836
(...)

while wd0 showed 0 (zero) errors.

after a while (almost 4/5 of the rebuilding done), first errors occured 
on wd0 also:

(...)
195 100    0     no  online  positive    Hardware ECC Recovered         
24580
(...)

is this something to be worried about? i guess yes :(

the drives are brand-new...

help is very much appreciated -- tia!
