BZip handles dropping the garbage off the end.
If that's true, you could just decide what the maximum limit of the file was and extract that. For example, if you know it's not bigger than 12 megs you could just grab 12 megs of the file starting at that bzip header. Then pipe it into bzip2's stdin. Any extra data at the end (assuming the above is true) would be thrown out.
Of course, extracting any files bigger than the block size of your partition will be a gamble. There's no guarantee that the file was stored in consecutive blocks. But since bzip files are generally created all-at-once instead of a piece at a time, the odds should be in your favor.
This all assumes i'm not misunderstanding something about the situation, drives, filesystems, bzip2, and uh... the state of the universe in general. ;)
