I have been getting numerous e-mails from the 'smartd' daemon with Subject: 'SMART error (CurrentPendingSector)' saying that
The following warning/error was logged by the smartd daemon:
Device: /dev/sda, 1 Currently unreadable (pending) sectors
It sent me 80 such e-mails over several months.
I ran 'e2fsck -cc', 'smartctl' and 'gsmartcontrol'.
'e2fsck -cc' did not report any bad blocks.
'gsmartcontrol' highlited the following lines in the 'smartctl' output:
--
ID ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
...
5 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail Always - 1179816
...
196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always - 17
197 Current_Pending_Sector 0x0022 100 100 000 Old_age Always - 1
...
-- these are highlighted in pink by 'gsmartcontrol', not in red.
i.e., it reports 1,179,816 reallocated sectors (is it meaningful??), and 17 reallocation events.
Still, 'worst' is equal to the 'value'.
/var/log/messages has occasional messages

# smartctl -l error /dev/sdareports several errors (below).
How do i interpret them? Should I replace the hard drive?
Thank you.
Detailed 'smartctl' output is below.
