Drive addition is certainly a possibility, depending on how you added 
it. As the sectors on your disk get used and ExtractStream seeks to 
the next sector, if it crosses a partition boundry and the partitions 
aren't correct, you'll get hosed -- that's what happened to me with 
MFS Tools restore.

I'm doing this from memory, but if you do:

bash-2.03$ od -a -N 512 /dev/hda10

You should see the ascii output of the first 512 bytes of 
your /dev/hda10 partition. If you look in the ascii, you'll see a 
list of linked partitions in the order that they're used.

Now if you fire up ExtractStream to do an extraction, you'll see a 
list of partitions it's using with the number of sectors on each 
partition. If the parition order doesn't match what "od" gave you 
above, or if there's another parition in the ExtractStream list which 
isn't in the "od" list, then you'll get garbage.

If that's your case, the only current solution is to hand-patch 
ExtractStream.
