I have a 2TB HDD connected by USB (WD Elements 25A2 (1014)) that I use to store my photos and as a Plex server on Ubuntu 16.04. I have been noticing it unmounting overnight recently for no particular reason, so I ran sudo badblocks -nsv /dev/sdb1
and it told me that there were too many bad blocks to count.
However when I go to gnome-disk-utility
, the option for "SMART Data & Self-Tests..." is grayed out. I can't figure out why. What can I do to access the SMART data?
