I have a Seagate 5tb external hard drive I use for storing various media. Today, I plugged it into Xubuntu 19.4. The drive made a few 'grating' sounds, the light indicating it is working came on, but Xubuntu cannot see the drive.
It does not register in Thunar, and
sudo fdisk -l does not display it.
Changing the USB slot I use, and typing
sudo fdisk -l again output the message:
Partition 1 does not start on physical sector boundary.
sudo fdisk -l stopped reporting the presence of the external HDD.
sudo fdisk -l hangs while trying to read the external HDD and I seem not to be able to end the task (
ctrl+c does not exit).
However, Thunar sees the presence of the drives, but cannot seem to mount them. I clicked on one of the partitions on the external HDD and now it is trying to mount, and so wont let me unmount either!
found another issue which looks like it might be a similar problem, but I am not sure what advice to follow in the link which pbhj provided.
If I plug the external HDD into a USB slot, then unplug it, it also appears that the USB slot gets 'turned off' by my laptop. Plugging in a mouse shows the mouse does not work, and other USB drives do not work anymore in the drive.
Can anyone help in diagnosing this issue?
