[comp.sys.atari.st] PD disk util

I'm looking for a PD (or otherwise) disk editor.  I had dl'd dvist.uue from
our Sperry 5000/85 to my ST and unarced it.  Unfortunately, I wasn't paying clos
e enough attention when I got an out of disk space before arc had finished 
dearcing and I hit <delete> instead of cancel.  Ouch!

To make matters worse, while trying to recover the file with Disk Doctor
(original 85/86 -- who knows if they ever had a newer version) I quit in mid-
stream because I thought the data in the sectors was starting to look a little
strange.  Wrong move.  I now have half the file back -- I guess that is better
than nothing except I've already dearced past that.

Back when I was using my Radio Shack Color Computer with OS-9, there was a 
great disk editor that let you read sectors into a buffer and then write them
out to another disk to recover as much of a file as you could -- really nice.

Anything like that out here?

I know where all the sectors are but how the FAT table points to the next
cluster and how to change that is still beyond me after reading the docs in DD.
(Well I guess not how it points to it, I understood that but rather how to make
it human readable and then make the changes).

I've looked at DLII to see if that will help but if it can do what I
need it isn't apparent.
