Developers: pricey utility but your support alone is well worth the $10... Thanks!

So overwriting a file 7 times with secure empty trash isn't enough? Who would go to all the trouble of trying to recover files from the trash? Perhaps the IRS if they need to audit you, or the FBI for whatever reason? And I'm sure they have their own methods of getting that info. Sorry developer, this just seems like a waste of $10.

A comment on the Gutmann method which many erase programs, and users, seem to think is necessary.

The Gutmann method of 35 passes was designed primarily for hard drives of a type which has not been manufactured for over ten years (MFM). Peter Gutmann himself has written that it is really not needed on modern hard drives and that a few passes with random data is sufficient. Especially given that it would take serious drive disassembly and custom minute examination to even attempt recovery of overwritten drives.

'course, its your drive and if you want to spend the time for 35 passes over, guess its your choice. And it does take rather a while on large files.
But for me, I now use tools and methods that are much less time-consuming because they require only a few passes of overwriting.

Secure Empty Trash does overwrite files in the trash 7 times, using the DOD-method, not 30 times using the Gutmann-method.

Permanent Eraser also overwrites 30 times; and it does this for free.

What does this do that mac os x does not?
when you put stuff in your trash can you can always choose from the Menu "Finder > Secure Empty Trash...". That, too, overwrites the files in the trash some 30 times.

Of course, the user has no way of confirming what is going on. It's just on the dev's say-so :)

Important: are file and folder *names* securely overwritten too? It's usually just the contents with apps like these...

Yes, the items are "destroyed" forever.. You can perform a simple test yourself, erase a file from an iPod or any external drive, and then simply plug the drive into a Windows machine. If you see (.thenameofyourfile) then the name has not been erased. if you dont have access to a PC, use the "show hidden files" Thanks to everyone.


But how can we be certain the destroyed file is being overwritten X number of times. Over thirty? How do we verify it's not 3?

As for the name being overwritten, if it is simply moved to a free space the filename won't show up even by a search for invisibles - right?

Thanks for replying

maybe it might be a good idea to include a realtime list message that displays the system's response to each individual shredding. It might take sometime...and there is the time delay issue. Another option is to make a log file that can be accessed by the user, which may display the above mentioned messages. thanks

Seems to be an excellent program. I'm uncertain about one thing though: it's incredible speed.

In the past using other programs designed to accomplish the same result, they all seemed to take much more time to completely obliterate a file or folder, as this programs claim to do? Any reply from the developer?
