[MrPolite]

Why do you want that? Had too look up purge BTW, and it looks like you want to use it up??? Am I right?



I borrowed my friends computer yesterday. Because he had a video editing tool that is really great on it. Sat up to 6am editing a movie. It said it would take 18 hours to render. And I had nearly 50Gb free space when I started.


I havn't looked at the computer before now, so I am not sure when it happend, but now it says that rendering failed, because the disk was full. And it has only been 7 hours. So it must at least have filled 50Gb in 7 hours, probably less.

umm ok you dont know what zero-filling is? what sort of a criminal are you!
when you delete stuff you can easily recover it cuz it's still on your hard drive. Windows only deletes it from the MFT I think... umm zero filling would be to write 0's on all the bytes on the hard drive (in this case on the free space bytes:) ) so the data couldnt be recoverable.
You see I'm trying to get away with some serious criminal record that I have on my computer :p jk jk

Thats not intirely true, there are methods that can recover data from the drive after its been zeroed up until 3 times.

I thinkg PGP and norton have this feature.

Quick google turns up:

lol thats theoretically impossible :) data recovery is only possible because when you delete a file, the actual bytes of it are not erased from the hard drive. Even in the same link you showed me there is another program that claims it does this: AbsoluteShield File Shredder let you permanently remove files and folders from your system easily without the possibility of data recovery.
anyways thanks for the reply :thumb: :wave:

Note quite,


AbsoluteShield File Shredder will completely erase files from your disk, without the possibility to recover it by any practical software or hardware methods.


There are methods which involve taking apart the harddrive and using sensitive equipment. but unless you have made enemies with CIA/FBI and such, you shouldnt have anything to worry about. :P

The only way to be completely sure that nobody can retrieve your data is to make it physically impossible to do so. I.E destroying the disk.

I saw a documentary about HDD recovery a few months back. A guy had formated his HDD, and then used a sledge on it before he did throw it away. But even then they managed to find his password for his bank account on it....;)

An other HDD had been in a fire. But the managed to recover that one too.


The only way I know that is pretty sure is to write new data many 10++ times over the same location as the old data was. Some apps do that. Not sure what they are called. But Norton Utilities might be one of them.

Yup. NAV has WipeInfo. Notice the Options...

NoteMe, but then the disk was not destroyed entirely.
If you chuck it into an industrial-strength garbage incinerator it will all melt, and if they can retrieve data from that they deserve to read it ;)

That being said, three to five wipes is enough to keep most people (including law enforcement) out, seven to ten wipes will make it very hard even for those mysterious dudes at the NSA (and equivalent organizations), any more than that and you're being too paranoid for your own good.

If you have disk with that sensitive data on, I would suggest never just throwing them away or selling them to someone else. Either dispose of them (see note on incinerators above) or simply keep them.
Barring the destruction of the disk, there is nothing you can do to all-out prevent someone from retrieving the data.

The safest storage is simply to remember it in your head :)
