Windows 7: Can files be properly erased from a drive?

The Cleanall function erases the entire partition. That means all files, folders, and the file system itself - everything.

A mentioned previously, Professor Gutmann wrote a paper outlining how data might be recovered from an erased disk. But the paper was written in 1996 and there is considerable doubt whether the method is of any relevance to modern hard drives. Gutmann himself has acknowledged this. It is also unknown how much data was ever recovered by this method.

In any event this method is far beyond the capabilities of any home user. The organizations that might be able to do this will not discuss it.

There are programs that will erase a drive with multiple passes but for most users this is clearly overkill. If the drive contains secrets that might be a threat to national security then this is justified - just in case. But for the rest of us it is just a waste of time.

Many organizations are requiring physical destruction of the drive before disposal. But this isn't because erasing the data isn't good enough. Physical destruction is quick and easy and the results are easily verified by simple observation.

...but if you want freeware to do this, IOBit Toolbox has a file shredder that uses gutmans method to erease file with it's file shredder, but i dunno if it's any good if you want to try it out, but just search around if you really want something to do this, there's always freeware that can do everything paid apps can, google's your best friend

In my opinion, I don't trust IObit software, especially their Malware Fighter, it is a frequent cause of BSODs from my experience.

Totally agree with x BlueRobot. IObit anything fits well in a dumpster.

CCleaner>Tools>Drive Wiper will do multiple passes up to 35! if you have the time. It will wipe a whole partition or simply those files marked deleted by the file system. This last capability can be very useful if you only want certain files fully wiped.

Been running that prog for years on a 32 and 64 bit comp/laptop no problems at all.

but going back the OP question deleted files have just the first digit changed so they are ignored

With todays large drives more than one pass would give you time to grow a beard long enough to trip on it.

I work in IT support for a large government. I was talking to a guy who had a F.R.E.D. (Forensic Recovery of Evidence Device). He told me he was capable of recovering data from drives that had been wiped (zero filled or other write over) up to seven times. I have no way of verifying this but that's what I was told. The Feds may have additional capabilites. I believe destruction of the drive is the only way to fully ensure confidentiality.

I've included a link to an awesome shredder:

SSI's Shred of the Month: E-Scrap - Hard Drives Shredding (Q) - YouTube

For some real fun check out them shredding metal shopping carts

It all depends on who is trying to retrieve the information.


Now if you have something very very special on a hard drive like old files from the KGB I would just through the hard drive in a furnace. Drink some Vodka and watch it turn into a puddle.
