I'm running ubuntu 20, and the SSD that died was running ubuntu 18.04. It was LUKS encrypted and suddenly died. I was able to access grub for a short amount of time but I no longer can. On my ubuntu 20 machine I'm unable to mount it, see it on fdisk and fsck says this:
sudo fsck /dev/sda
fsck from util-linux 2.34
e2fsck 1.45.5 (07-Jan-2020)
fsck.ext2: No medium found while trying to open /dev/sda
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
sudo cryptsetup open /dev/sda luksrecoverytarget --type luks Device /dev/sda doesn't exist or access denied.
Finnix says that its able to see the partition but I still cannot mount it or even unlock it. I have little hope in saving it at this point, but I need help its the last 18 months of my work, no backups.
fsck
on an encrypted block device (instead of its container). Not really sure if there's anything left you can do if you can't even open/unlock it...(it's pretty much the point of encryption)
