I'm not used to using smartd, but have a new set of systems that don't have any sort of RAID on them, so I enabled smartd (18 systems 4 SATA drives each).
Running CentOS 5.4 64-bit ..
One of them has emailed me twice(despite it saying it would only email me once) saying it has
1 Offline uncorrectable sectors
But when I try to find more information, smartctl seems to think everything is fine.

/var/log/messages has tons of entries that say
Device: /dev/sdc, 1 Currently unreadable (pending) sectors
Since it's only 1 disk out of 72 I suspect it's the disk at fault rather than something with smartd..
Any ideas?
thanks
