I have an encrypted hard disk with luks encryption. When I try to open it via:
cryptsetup luksOpen /dev/sdc1 backup
It prompts me for a password, but then errors out on me:
device-mapper: reload ioctl on failed: No such file or directory
My device still has header information, though:
LUKS header information for /dev/sdc1 Version: 1 Cipher name: aes Cipher mode: cbc-essiv:sha256 Hash spec: sha1 Payload offset: 4096 MK bits: 256 ...
I'm just making up the word
backup. Do I need to register it somehow? Is my data recoverable?
