[kwlug-disc] Hard disk smartctl errors

This is the output so far, with -vv

About to copy 474388 MBytes from /dev/sdc2 to /data/ddrescue-20141015.img

Trimming failed blocks...

The number of errors (1465 above) keeps decreasing! Yes, decreasing.
It was 1775 about 8 hours ago. I assume this is a good sign.

Also the average rate keeps decreasing. It was 539 kB/s this morning.
This means around 12.5 days to go ...
