  1. Sorry, I clicked reply before you posted about the wipe free space feature only performing one pass. I turned the overwrite complexity down and it still took the same amount of time to do 1%, so you're right about that. Thanks for the support guys.
  2. I had heard about this, though when it comes to sensitive data I'd rather be doing too much as opposed to finding out that one overwrite isn't enough when somebody is dining out in Prague at my expense. I'm quite pleased that the PC is still usable when running CCleaner, but if it was sacrificing overwrite speed by limiting how much power it used, I'd find that quite counter-productive. I had a feeling that might be the case. I suppose I'll have to use a less complex algorythm for the big wipes. It's about 800GB once you subtract the OS and backup partition. Haven't put a great deal of data on it yet, so I suppose I must either have a fast disk or the software isn't doing it properly.
  3. I recently got a new computer with a Dual Core processor, four gigabytes of RAM and a one terabyte hard-drive. I wiped the free space recently using the 35 passes algorythm, and it took three hours. Of course 1TB is a lot to overwrite, but the thing that bothered me was that CCleaner was only using 3% of the CPU and 33% of the RAM. On the old computer it would use as much of the resources as it could. Is there any way I could make the program maximise its efficiency and capitalise on all of that free power? I'm hoping that could cut the time it takes significantly. I'm running Windows 7 if it makes a difference. Thanks in advance.
