Please dump the existing superblocks to files and send them to me (they do not contain any sensitive information) with commands dd if=/dev/sdb1 bs=1k count=4 skip=64 of=sdb1-sb0 dd if=/dev/sdb1 bs=1k count=4 skip=65536 of=sdb1-sb1 to see if the data at least resemble a superblock. david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
