Thank you for the reference! I am downloading it as I type.
As the drive does not have a valid file table, how can the software identify the length of the file? If this works well, I will be forever grateful.

There is a forensics tool called formost that searches an binary file or block device and pulls out all the files that match their headers. The site is at http://sourceforge.net/projects/foremost/. It doesn't have the signature for bzips but here is it: "bz2 y 10000000 BZh?1AY&SY"
It will have some false positives but it will find every bzip on the disk. Let me know if you have questions.

Thank you for the suggestion.
I have read the manual, including the recovery section. It deals with the recovery of non-corrupt blocks from a bzip2 archive with come corrupt blocks. I believe that these bzip2 files are intact, but as I have no file table on the drive, I have to identify the length of each archive. I was hoping to identify either a long which would identify the total number of bytes in the file, or an end of file marker. I have not found either. I am reviewing the bzip2 source code, but have not found what I am looking for yet.

A quick Google search for "bzip2 file format" yielded this documentation page:
http://www.digistar.com/bzip2/docs/manual_toc.html
There's a section called "Recovering Data from Damaged Files" but the
link apparently isn't working. Perhaps you could poke around the
net a
bit and find the documentation mirrored somewhere?
