The enclosed batch file will test whatever DoubleSpace CVF it is
run on and may very well break it and destroy data.  You should 
create a small, empty CVF to play with. 

Create a small CVF

Run CORRUPT.BAT

What CORRUPT.BAT does is first run BUST, a small C program that
writes and deletes a large number of small files to simulate heavy 
disk usage.  Then it uses the DOS COPY command, with the verify 
switch for safety, to copy some files. The COPY command will suceed
along with the verify. Then it compares the original files with the
destination files. In many cases, many of the destination files 
will contain NOTHING but zeros!

Use this program to see if your DoubleSpace setup is working correctly. 

Read DBL-READ.TXT for instructions on DoubleCheck, a utility which monitors DoubleSpace for 
dangerous conditions and signs of past trouble.
