Failing Hard Drive, or False Alarms?
A couple of weeks ago I upgraded to trixie. Since then I've gotten
a number of messages like
Device: /dev/sda [SAT], 8 Currently unreadable (pending) sectors
and
Device: /dev/sda [SAT], 30 Offline uncorrectable sectors
These seem to come within a day or so of a reboot, but it hasn't
been long enough to know if that's a red herring.
I ran "smartctl -t
offline /dev/sda", and the eventual result of
"smartctl -a
/dev/sda" shows

I admit I'm not a smartctl wizard, but to me it seems that
smartctl is contradicting itself.
Can anyone help me out?
