JSL

I have a problem with running the partition program of Windows 7 after I ran Defraggler. The program will only shrink a drive down to the last bytes used on the drive. When I started that was at 135000 bytes. After running Defraggler it put one block of data at the end of the drive and now I only have 144 bytes that I can shrink. Does anyone have any idea how to move that away from the end of the drive? Thanks for your help.
