My computer`s hard-drive started to give some boot-related errors after a reboot. After running the in-built diagnostics tool of my computer, it found out that, it can no longer detect the hard-drive. I have removed the hard-drive from the computer and plugged it in into a external hard-drive casing. I got this message when I tried to mount it.

Error mounting /dev/sdf1 at /media/bogac/02c44f1d-8974-4bec-8b20-69d9d58be1fd: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdf1" "/media/bogac/02c44f1d-8974-4bec-8b20-69d9d58be1fd"' exited with non-zero exit status 32: mount: /dev/sdf1: can't read superblock

If I try to benchmark the disk from the gnome-disks then I got the following error.

Error opening /dev/sdf1: No such device or address (udisks-error-quark, 0)

Can you please guide me how to solve this problem ?

Thank you for your help

    I'm voting to close this question as off-topic because the hard disk drive cannot be detected internally by the BIOS so is most probably dead, which is not an Ubuntu problem but a hardware one...

Drives fail. Not frequently these days, but they do. Yours probably did. Just restore from backups!
