Your hard disk fails on Linux - now what?
I happened to me a few times in the last few weeks. A filesystem check for a hard disk would take for ever - my system won't boot. One of the harddisk was reporting errors. At this time i have four different hard disks that are giving me trouble. All broken harddisks have been taken out of the system and I am analyzing the problem using a virtual machine and a USB-SATA bridge.
First step: remove harddisk from system
Hopefully your disk is not needed to boot or fully operate your system. In that case you might want to boot of a USB stick or other media. In any case my procedure is to remove the disk from the original system and use a different system for analysis. In my case i am using an Ubuntu based virtual machine and connect the drive via a USB-SATA bridge. With USB 2 devices the performance is poor. I am not using my old Logilink QP002 Sata Docking Station anymore for this reason.
The USB 3 device i bought in 2015:
still serves me well.
