   up to "Once you click the shrink button Windows will shrink your 
drive. Once it has completed shrinking your partition, the Disk Manager 
will display this new space with a black header meaning it is an empty 
partition, you now need to give it a file system. To format the drive 
with a file system right click on the black space and select “New Simple 
Volume”.

   So set the size then drive letter.
   The format partition step of the wizard is where it goes bonkers.
   After supposedly formatting, i get the wonderful killing message box:
"The format did not complete successfully     OK".
   Most definitely *NOT* ok.

   DOA, cannot put anything in second partition.

   So what program can i use to fix that?

     Thanks,  R. Baer
