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?

  • Some SATA-USB interfaces/adapters do not support SMART.

    Probably you need to connect it to a native SATA controller.

I have found that some external hard drive interfaces do not support the SMART function. I have two interfaces/cases. If I put a drive in one I get no support. Put the same drive in the other and SMART function works just fine.
