Today I installed CCleaner and after using it to clear cookies and temp files (ie: regular cr@p), I decided to wipe the free space on my hard drive, the reason I downloaded CCleaner.
I went to:
Tools > Drive Wiper > Free space only/ Simple Overwrite (1 pass), selected (D:) and clicked Wipe.
My data (D:) has about 260GB of free space, so I expected quite a long time of overwriting.
However, at first the percentage bar was increasing rather rapidly, but the remainting time was also increasing (instead of decreasing).
After a while, it changed to: .....MB of 200MB. That number climbed until it was 200MB and then the wipe stopped.
What happened there? Why did it wipe only 200MB, and not all 260GB?
Edit: You need to supply more information:
1. Your Windows operating system version.
2. Version of CCleaner you're using.
3. Other resident software that's running such as the antivirus you use, etc.
Maybe try this, although I don't know if it will help:
1. Start CCleaner.
2. Click "Options->Settings" then under "Wipe Free Space drives" select the drive(s) you wish to wipe the free space on.
3. Click the large Cleaner icon at the upper-left, then under "Advanced" tick/enable the box "Wipe Free Space".
4. Once Wipe Free Space has finished then under "Advanced" untick/disable the box "Wipe Free Space".
Possible reasons Wipe Free Space may not work could possibly be other running software interfering.
Edit: Also maybe running a ChkDsk on your computer may help.
Personally whenever I use it I:
1. Disconnect from the Internet.
2. Turn off real-time shields in my anti-virus/anti-malware - which could possibly be the biggest interferer.
I am using
- Windows 7 Home Premium 32-bit
-CCleaner v3.10.1525
- McAfee AntiVirus plus
I will look into the things you mentioned.
