Hi there, Please resend the dumps in ASCII as Arno suggested. Meanwhile: It seems the disk has no partition and starts with a LUKS-Header right away. While the LUKS-Header itself seems to be consistent (at first glance) the keyslot itself could of course be damaged.

Hi Sumaya,

that looks like you have a LUKS container on the raw disk. Not a problem in itself, just a bit unusual. The luksDump info looks fine.

You can still have a problem in the key-slot. To check for that, please compile and run the keyslot-checker and post its output here. If it finds something, also post the output with option -v, unless that is too long.

You find it in misc/keyslot_ckecker in the source-package. It will look for areas of possible corruption in the keyslots.

Regards,
Arno
