Hmmz.
I have a disk which gives the following results:

# smartctl -a /dev/hda &>/dev/null
# echo $?
64

What does error code 64 mean?

"RETURN VALUE" section of the manual is not very clear to me.

According to it:

smartstat=$(($? & 8))

gives 0, so, is the disk healthy? Why the error code 64 then?
