Well, headers seem to be ok. cryptsetup luksDump finds it without any problem. xxd /dev/sdc1 |head -n 10 0000000: 4c55 4b53 babe 0001 6165 7300 0000 0000 LUKS....aes..... 0000010: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 0000020: 0000 0000 0000 0000 6362 632d 6573 7369 ........cbc-essi 0000030: 763a 7368 6132 3536 0000 0000 0000 0000 v:sha256........ 0000040: 0000 0000 0000 0000 7368 6131 0000 0000 ........sha1.... 0000050: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 0000060: 0000 0000 0000 0000 0000 0408 0000 0010 ................ 0000070: e00b 50a0 0042 ae4a cd71 ccff 4b8a b701 ..P..B.J.q..K... 0000080: 8872 f723 19d5 c1d6 945c 8aed c3b4 703b .r.#.....\....p; 0000090: a2e2 a755 961d b2e9 fd06 59f3 0ecd 42a6 ...U......Y...B. The problem is that the first sector of disk, where partition table is hold was altered with this damned swap partition of 2gb. Maybe there is any way on how to create artificial partition table manually that will be correct for dm-crypt to work? And then write it to this drive using dd or smth.
