I recently loused up my hard drive with one of my programs and was hoping 
someone out there would be able to help.  I wrote a little program which filters
out unwanted strings from really huge text files (I.E. $20 $0D $0E would be 
replaced by $09 wherever it occured).  Well, the idea was that the program would
go through one file, making the necessary changes, then writing out to a file 
it creates.  Since this was a small, quick program, I didn't bother with things 
like checking to make sure I didn't get a disk full error after doing an FSWrite
(mistake #1).  So what happened was, after running for a while, the disk became 
full, but my program kept going, oblivious to the situation.  I saw no disk 
lights going, assumed my program messed up, so I hit the reset button 
(mistake #2)..  So effectively, my program created a file, wrote a bunch of 
stuff to it, then quit, BEFORE doing an FSClose.

When I got back into the finder, I noticed my HD was full, but the file that 
should've been created was non-existant.  So somehow, my program caused the HD 
to think there was space being used for this file, but there is no such file, 
nothing for me to delete.  I tried several HD utilities to no avail.  Can 
anyone help out?

Also, along the same lines, does anyone know of a program which will allow me 
to enter a "to search" and "to replace" string in hex, and have the program go 
through a text file, replacing every occurrence of one with the other? 
(I.E. $20 $0D $0E would be replaced by $09 wherever it occured)?

Any help would be greatly appreciated!
