Under TOOLS>DRIVE WIPE>WIPER> CCleaner gives you the option of wiping "Entire Drive" yet when I make this selection, the C: drive as well as the WIPE button are greyed out. I want to completely clean the hard drive on a computer that I will be donating. Will this program do that? How to I get it to work, please?
You can't wipe the entire drive when the windows system is running from it, ccleaner needs windows to remain in place and not be erased while running. System drive can have its freespace wiped but not erased as it causes a paradox.
Hi weybrew,
you will either need to remove the drive and connect it to another PC and re-format it, or if it has to remain in-situ, you could reload Windows and part of that process allows you to delete the partition and re-format the drive.
with the former, you can do a low-level or quick format, with the later (from memory) only a quick format is available.
it'll all depend on how sensitive your data was.
Thanks for your replies, mta and Nergal. I was not skilled enough user to understand how this works. I have a better understanding now.
