I've had a look at some of my drives' SMART output, and only my Samsung
drives have it - one showing 57 (with zero reallocated, pending or
offline sectors) and one showing 331 (zero reallocated, one pending and
zero offline sectors). Neither drive has ever given a read error, and I
do run a weekly check on my arrays which has never reported any mismatches.
Googling for this field doesn't give any indication that it is relevant
to determining whether a drive is failing, but if someone with more
SMART expertise can comment I'll be quite happy to be corrected...
Having said that, all of Gavin's drives apart from sdc show non-zero
reallocated sector counts, and that field definitely is one to follow
when considering replacing drives.
Cheers,
John.
