I've been using Ccleaner for a couple of years now om my IBM Thinkcentre M52 with Windows XP Professional SP3 without any problems. I usually wipe the free space on my hard drive weeky which used to take about 30 minutes. After I downloaded the newest version 4.11.4619 my computer now tells me it will take 24 days to wipe the same amount of free space. I tried going back to the older version of Ccleaner but it still wants to take 24 days. Anyone have any ideas what might be going on?
Most likely situation is you've changed the overwrite method from one pass to multiple. Go to Options -> Settings and make sure secure overwrite is set to "Simple Overwrite (1 pass)"
The other possibility is you've utterly thrashed your hard drive by zeroing it out far more frequently than you should.
