Hi, it's been a while.

My machine didn't want to boot anymore.
After a few tests, it's my SSD : it's not detected anymore.
After some research, it seems it's dead.

I tried the SSD on another machine,
and although I can't detect it on gnome-disks or in sudo fdisk -l,
it IS listed as /dev/sdb in lsblk!
Btw it's encrypted, so I must chroot before I can mount it.

So I tried to detect it in Gparted, but it's hanging.
I tried to chroot/decrypt it, but it's also hanging:
1. sudo modprobe dm-crypt
2. sudo cryptsetup luksOpen /dev/sdb* linux (also tried sdb1, sdb)

And here's dmesg, before and after plugging the ssd:

Do you think there's a chance I could still access it,
long enough for data recovery (or should I move on)?
