Extra Drive letter in my computer

[Fayed]

I have completed installing pinical Studio 8 and 2 new drive appeared in my computer. New drives are copies of drive c and D. They are not visible in disk manager and thier drive letters are not usable.

I have uninstalled the software and the problem remains the same.

I tried to restore windows to a previous restor point but the process dails...

Can Any one help me with this issue

Regards
