I have installed the 30 day trial of JV16 Power Tools 2007. I attempted to do a disk wipe on my external Acomdata E250 drive. I understand that the tool wipes the drive numerous times but my issue is the progress bar. When I run your software on my older desktop, the progress bar moves from left to right as the wipe progresses. When I run it on my external laptop drive, the progress bar continuosly jersks back and forth so I can never tell what the actual progress is.
