It’s the second time I have an error like this with two different drive and even one new !
The only thing this two drives have in common is that I use them on a new machine with endeavour sway edition.
Suddenly one day I decrypt the drive (luks encryption), it works then when I try to mount it I got that:
can’t read superblock at adress /dev/mapper/name
So I try:
sudo fsck.ext4 -v /dev/mapper/name
/dev/mapper/name : clean, 46080/122332032 files, 304704905/488374272 blocs
And the drive doesn’t show up (with lsblk or on gnome disks) anymore unless I reboot.
I found the problem finally, it was a silly one, my sata cable was faulty !
The drive ceased to function when I was trying to access the partition therefore the mount command can’t found the superblock .
