hmm I'm still trying to unravel the file contents structure in an effort to recover data.....

Does anyone know whether the TIB file contains an MD5 hash as the footer? My thoughts are that if I can append a valid MD5 footer at the end of file then maybe TI can be tricked into thinking the file is valid and mount......

My understanding of a TI tib file is:

Each 256K of data that is written contains its own checksum.

If an archive is to be restored every one of the checksums contained in the archive must agree perfectly iwth the ones calculated from the data read into RAM or the archive is declared corrupt and nothing is restored. This 4000 checksums per gigabyte.

If files are to be extracted from the archive then the checksums pertaining to the blocks of data containing the files must agree.

In other words, I doubt that TI is basing its validity determination on a single hash at the end of the file - but I don't really know for certain.

Good luck!
