Running smartctl(8) each day with -x, or -a on old versions that don't
have -x, recording the results, and diff-ing the last two is a simple
way to monitor changes in hard-disk state and learn what's normal so

A manual `scrub' of a hard disk, using dd(1) to *read* all the sectors,
lets the drive recover data that's getting a bit hard to read before it
becomes difficult or impossible, and increments the `reallocated sector
count' shown by smartctl.  Better than discovering lost data in six
months' time.

Cheers, Ralph.

Interesting from the other table.  Thanks Ralph.

Now: what are the other features of DD? Can it be used to tidy up a hard disk and make it respond faster?  When I open Chrome the HD thrashes around quite a lot before Chrome comes up.
