[TriLUG] HD failure eminent?

[Michael Hrivnak]

Brian,

If i recall correctly, "passing" a SMART test only means that catastrophic 
failure is not expected within the next 24 hours.

It looks like you haven't used the SMART tests.  Try both of these:

smartctl -t short /dev/hda

The results will show up in the output below.  Then try:

smartctl -t long /dev/hda

After a while, those results will also show up in the output below.

I recently worked with a drive that passed all the SMART tests but 
consistently was producing errors, which were demonstrated in the above 
mentioned tests.
