I think I'm on the verge of getting all my data back; the only missing
piece is to recalculate the crc checksum of my altered superblock and
I'm having trouble finding the correct function/method; the data I am
checksumming is (based on the sheet) 0x20 (directly after the
checksum) to 0x32b + n (226 bytes); if im doing something wrong let me
know; or if theres a quick/dirty way to get the right checksum
..soo close...

The checksum seems to be from 0x20 to 0x1000.
