I thought it was the disk with the OS that was the problem so I bought a new one and did a fresh install and now the computer is again up and running. But I'm having problems with accessing the old failed disk. I can see it with gnome-disk-utility and it says that the disk is OK but has 8 bad sectors. I can mount the boot partition from it and I can decrypt the main partition. But then I can see no way to mount the main partition. It is a LVM physical volume. >> >> Any advice? > > Show us the output of (after decrypt): > > lsblk -f > > or directly - try: > > vgchange -a y > > mount /dev/mapper/"main partition" /oldfaileddisk > > > -- > LF > If you think the disk is going faulty the very first thing to do is to make a copy of it and then work on the copy. If your failed disk is on (as an example) /dev/sdc, the command is: # dd if=/dev/sdc of=/home/dd-copy-of-sdc It will take a long time, and ensure that /home has enough space for the complete disk. Use kpartx(8) to make the disk visible and you can then mount the partitions. lvs(8) will tell you about any logical volumes and IIRC, lvchange allows you to activate them. You can then mount them as normal.
