hi! i would like to know which file shredding program is the best now. i try to search on Google and theres alot of results all claiming to be the 'best'. But i hv read somewhere that not all of them is what it claims as some of them just use simple deletion methods and could simply be recover

I would like some thats really 'secure' and hopefully not taking too long time to do the job.

thank you,

Hello aboka,

Eraser is an advanced security tool (for Windows), which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. This program is free.

Are you trying to erase individual files, or wipe the entire drive?
The most effective programs are those that will wipe/re-write across the entire disk - even then, files can be recovered with the right knowledge, equipment, and programs.

Check out this link for creating a CD or floppy to do a 'disk wipe': (http://dban.sourceforge.net/)

no one is the best, only one is just suitable for your requirements.

you may search for some forensic software which can make the deleted data unrecoverable. the following one is an example. you may find more from here.

Mutilate File Wiper 2.94

hope it helps,

A good start for cleaning up hard disks is to save data  just encrypted.

E.g. you encrypt a partition / hard disk with truecrypt the opensource hard disk protection tool: www.truecrypt.org

After mounting the partition (entering a passphrase and assigning a driveletter) your special harddisk becomes ready.

Now you can store all kind of files, images, videos, emails on it. After the partition is unmounted all data is again encrypted.

So now after you formatted that drive, because it was of no use any longer, e.g. you want to sell the hard disk, let someone try to recover your files. It will fail, because all your data was never stored unencrypted on the drive so the forensic tools won't detect any known file patterns, plain text and such.

I think a single random wipe on an AES encrypted partition should be enough for all cases.

The forensic software 1st has to guess the encryption tool, then break AES then unerase your files. Quite a hard job...

>  thats really 'secure'
please define "really secure"

there is no "best", just one that "fits best" your requirements (which you have not specified yet:)

may be wipe (Unix/Linux) or sdelete (windoze) is what you're looking for ...

what i mean by best is to make it really difficult and takes a lot of times to recover even for an expert(if its not possible to make it unrecoverable) and do not takes too much time

thank you,

Here is all I could find in a quick search:

Description: This week Steve and Leo explain why they love "TrueCrypt," a fabulous, free, open source, on-the-fly storage encryption tool that is fast, flexible, super-well-engineered, feature packed, and able to provide advanced state-of-the-art encryption services for many applications.
http://www.grc.com/sn/SN-041.htm

Schneier hasn't tested it: http://www.schneier.com/blog/archives/2006/05/truecrypt.html

"Has it been reviewed by any security professional (like yourself, Bruce)?"

Not that I know of. That is, I haven't recviewed it, and I don't know of anyone else who has.
