Knew I forgot to add something. SMART looks fine (see below), though I
haven't run a new long check (and will only do so once I've done
copying the data from the device (I should have still 2 further backups
of it, though also on Seagate ST8000AS0002).

I think all values are pretty normal (all Seagates seem to show these
high numbers for Raw_Read_Error_Rate, Seek_Error_Rate and
Hardware_ECC_Recovered. Never had a Seagate disk which didn't. Guess
it's normal for them).

The only thing which is a bit strange are the:
Command_Timeout 6
High_Fly_Writes 5
though I have low values of these on most of my
ST8000AS0002.
So I'd blindly guess it's mostly normal, too.

Does anyone know something different?



Thanks,
Chris.
