Missing Hard Drive Space After Using Windows 7 Disk Management Tool

THIS HAS BEEN SOLVED.


I used windows 7 disk management tool to make a new partition.
It didn't work and I kept receiving an invalid parameters error.
I restarted my computer to find that my hard drive was partitioned.
I extended the drive back and rebooted.
Now in windows explorer I am at a loss of about 200 gb of space.
The space is apparently missing.
I will attach two pictures.
One of the Windows explorer and the other of a tool I used called partition wizard.

and here is partition wizard

Partition clearly shows that I have all the space I originally had, but windows explorer doesnt.
How can I fix this?
Thank you for everyone's time in advance.
All help and info will be greatly appreciated.

Hello xlad mate have a look see in DISKPART at the drive there - take the SD out first to stop it being listed.

In PW right click on the C: and > Explore see what there is listed too.

The Explorer shows the correct number. Something is wrong with PW. Try the bootable CD version of PW.

If I'm out of hand hit me beat me.
It doesn't matter what a 3rd party program sees just what Windows 7 sees. Windows 7 has to work with the used and unused space it sees.

I found the culprit and solved my own problem.
I had defragmented my hard drive and found out the majority of the space was being taken up by my backup program Rollback Rx.
I defragmented my snapshots from my hard drive and i received all my hidden space back.

Glad it is fixed mate and by the way DISKPART you do through the command prompt

Start > type cmd > in the small window at the top of the Start up menu block > right click and run as admin > at the prompt - type DISKPART (upper or lower case) you will get a screen like mine you will see what I have listed with the various commands
