Hmmm, Ok, I can see that. The errors are confined to one slice on the 
disk (ad1s2e) the other slice fsck'd fine. so I should be able to 
recover that data using a FreeSBIE cd and writing to a new drive. The 
damaged partition I can *hopefully* recover using dd_recover. Once I do 
that I'll try the drive in another computer and see if the problem's 
still there.

we'll see.....
