I'm using Ubuntu 16.04 on Dell Vostro.
I have a problem to use external hard drive. When I plug it, first it works, but in some time it unmount by itself (while reading data or not).
While the drive was mounted, I tried to open GParted, got the warning
input/output error during read on /dev/sdb, and had to kill the process in the terminal.
I tried to use
smartctl, but it failed:
$ sudo smartctl -a dev/sdb | less dev/sdb: Unable to detect device type Please specify device type with the -d option.
First I thought that the external drive is broken, but I've tried with another one, I was also trying to change the USB cable and the behavior is exactly the same.
I still can see the drive in Nautilus, but I can't open the folder (
Unable to access location. Can't mount file) and I can't see it with
I use the USB ports with my phone without any issues, so I assume that they're fine.
dmesg in terminal. The output is long, I'm pasting only the lines which point to errors:

I didn't find what
error -110 means.
Thanks to the comment I've managed to run
smartctl. There is part of the output of
smartctl -a /dev/sdb | less:
