Hello. I have a question. So I'm at college working off of an old windows vista that I've reformatted to be a Windows 7 Ultimate Edition. Well, I have two main drives on my computer, Recovery Drive (C:) and OS (D:). I currently have my Windows 7 Ultimate Edition formatted to my Recovery Drive (C:), but my Recovery Drive (C:) only has about 10 GB's of space and its full, not allowing me to install any programs, and disturbing the performance of my computer. My OS (D:) which has 136 GB on it, is also full but I would like to wipe my OS (D:) drive and reformat THAT disk to have Windows 7 Ultimate Edition on it. However, when I use CCleaner to wipe the drive of OS (D:), after I type ERASE into the message box, an error message keeps coming up saying ACCESS IS DENIED. I cant seem to find any topics about how to fix this, and I don't know what to do myself. If anyone can help me i would very much appreciate it.
