Terafall February 15, Usually a single overwrite is enough to prevent usable data being restored from a drive. The area that contains the data is marked as free, but the data is not actually overwritten until a new file is written in exactly the same place sometime later.

Thus, until that overwrite actually happens, we have the ability to "un-delete" a file using tools like Recuva. CCleaner's Drive Wiper is one example of a tool that is meant to remove this ability to undelete. The concept is simple.

The drive wiper just writes data of some sort in all of the spaces on your hard disk where no files are currently stored: As a result, anything left in that free space that could have been used to recover or un-delete a file is removed.

It depends on just how sensitive the data that could be recovered might be. In general, with browser caching and temporary files and who knows what else, it's pretty safe to assume that there's some sensitive data in the unused areas of your hard disk.

It depends on just how likely it is that your hard disk is to fall into the hands of someone else - either by loss or theft. It depends on just how likely it is that someone who ends up with your hard disk will bother to see what's in the free space.

It's that last one that, for me, reduces the need for free space wiping to near zero for most people. We're just not that interesting. And, perhaps more to the point, there's probably much more interesting stuff in the files that haven't been deleted.

If a thief wants to go spelunking for data, they'll probably find plenty in the files and folders that already exist. On the other hand, perhaps you are the target of someone's attention. Perhaps you do have a sensitive job or work in a sensitive industry where data theft and espionage are not only possible, but even likely.

There are several additional steps like encryption that you should be taking, but when it comes to free-space wiping, then I'd be doing it often. A simple overwrite does exactly what's described above: As I discussed in What difference does multiple-overwrite delete really make?

The solution is to overwrite it more than once. CCleaner offers the option of overwriting 3, 7, and even 35 times. Three's probably plenty, but if you're in some top-secret government agency, perhaps you'll want to consider more.

What difference does multiple-overwrite delete really make? Deleted files may be recoverable. Overwriting data makes it impossible for common tools and multiple overwrites make it impossible for any. Secure Delete is a way to make sure that when you delete a file it cannot be recovered.

Understanding Secure Delete is important to protect sensitive data properly. Is deleting a file and emptying my recycle bin enough? Deleted files might be easily recovered unless you take additional steps to ensure that they're not.

I'll look at why and what to do. Shredders or Secure Delete tools actually address two distinct problems, only one of which applies to Flash. Addressing the other could be harmful. I did a complete reset to factory settings and lost that video I thought I had it on a disk - I was wrong.

The last reset was done well over a year ago. I know I've used CCleaner in the past but don't believe that I've used it since my last reset it's not installed on my computer now. If someone works for an ultra-top secret company and possesses some super sensitive information, would not the person's company give a seminar or tutorial on how to keep their data safe?

My son works for a large aircraft company and the designs are highly secret. They now crush all old hard drives and incinerate the debris. I run CCleaner on a daily basis — before I shut down my PC for the night possibly overkill, bit it only takes seconds to run on my machine.

I have noticed that CCleaner takes differing times to run depending on the particular browser you're running. Firefox is around seconds, Chrome around seconds, and finally IE x anything up to minutes!

This seems to be caused by the way each browser organises its caching. I'm guessing that were one to run CCleaner for the very first and only time on a machine, there's a chance it could take three hours to finish its scan, particularly if you've been tardy with your PC's "housework" over a lengthy period of time.

I always use CCleaner's three-pass method as I reckon this is more than sufficient for any average home user. I agree with Leo that 37 passes, whilst not only massive overkill, is a pointless waste of time better spent doing other system housework.

The person asking the question wasn't using the cleaning function, but the drive wipe function which can easily take a lot of time. You can get a free version of Recuva just click on the underlined 'Recuva' word itself in this Leo's article which will then take you to his another article on Recuva where there's a link to their official website with a download of a free version yes, Leo always does re direct you to the official website s of whatever he recommends.

No harm to try Install it and perform a recovery. Unless you don't want to install something that you wouldn't use often enough. But how important could that deleted file be to you? At the end of the day you can always uninstall it.

I recall there's also a portable version of free Recuva not sure if still, but recall the discussions about it, - just browse the comments in Leo's article on Recuva. Shelly, btw, talking Recuva is slightly off the topic in this article - sorry!

Best, search Leo's answers first!
