"Pre-fail" is the name (or description) of that particular SMART
counter, as is "Old Age". If there were positive and increasing values
in those rows, it could indicate a pre-failure condition. A brand new
drive still has prefail and old-age counters, even though it may not
fail or be old for years to come.
This just looks like you have an older drive where the counters are no
longer within acceptable range.
Do you have power management on this drive?
This could also cause that ABRT error.
The gist is that the read/write head on these drives parks itself too
often. While this does result in power savings while parked, the
drives are only designed to support 300k parks (consumer drives) or
600k parks (enterprise/RE2 edition).
Either way, the smart data will show how many times the head has been
parked via the "Load_Cycle_Count" parameter.
An (edited) example:
smartctl -a /dev/sda
Power_On_Hours 3377
Load_Cycle_Count 97972
The "solution" so far has been to use the "wdidle3.exe" DOS utility
provided by Western Digital to change the head-park idle timer to a
different value (or disable it all together).
