Ok. > dd if=/dev/sr1 bs=2048 skip=1256112 count=1 \ > | dd bs=1 skip=158 count=4 | od -d > 0000000 46890 4864 > This value surprised me a bit, it is unlikely > even close to a possible offset. Indeed. 4864 is much too high. The bytes in question are: > 0000220 ... 267 * > ... b72a > 0000240 023 \0 \0 023 * 267 > 1300 0013 2ab7 man ascii ... Your od -d probably interprets 16 bit words MSB. We need LSB, resp. have to read the MSB duplicate = 0x00132ab7 : $ expr 19 '*' 65536 + 42 '*' 256 + 2 '*' 64 + 6 '*' 8 + 7 1256119 That would be an offset of about 2.4 GB. (please check my conversion of 0x132ab7 by a hex calculator) So my bet is 1256119 - 28 = 1256091 provided that your first sessions show 1c00 0000 at byte 158 (octal 0236) of block 16.
