Help renaming my HD partions !!!

[guest]

I installed Windows 7(32bit) yesterday as my previous windows 7 had got corrupted. But i noticed a strange thing. All the partion's name got changed to Local Disk. I tried renaming them but failed. Whenever i rename them, they get changed to Local Disk Except C: which is the boot drive. But the name is changed accordingly in the Disk management. Here is the screenie !!

You could run this to make sure this version isnt corrupted - right click command prompt, and select - run as administrator - type this in, and hit enter - SFC /scannow
