Permanent Eraser allows you to securely delete files. When you normally delete your files in Mac OS X, the operating system is only forgetting where those particular files are placed, while the data still physically remains on the drive. Beginning with OS X 10.3, Apple enhanced its security by introducing the Secure Empty Trash feature, which follows the U.S. DoD pattern of overwriting data seven times.

Permanent Eraser provides an even stronger level of security by implementing the Gutmann Method. This utility overwrites your data thirty-five times, scrambles the original file name, and truncates the file size to more...

Great App does what it says!

There definitely needs to be a check box in the preferences to keep the app open even when its not trashing files. So that you can drop files onto its icon in the dock.

It would also be great if you could add an Erase Free Space option, as well as for other drive selection.

I drag it to Finder's toolbar so I can easily secure delete files from any Finder window (I do the same with AppCleaner too).

I dragged the PE app icon to the Dock. Now, I merely drop the target file/folder on the PE Dock icon, and voilà, it erases according to the established preference setting.

I like this! It's a simple app that securely erases files (it defaults to Gutmann 35-pass, but you can change the erase method in prefs to DoD 7-pass if you want) with no muss and no fuss. I like that I can use it without a dock icon or menubar icon if I want, and there is the very useful option to install a service that appears at the bottom of the contextual menu as "Erase" (look for this option in prefs). It's great deal for the price of free.

BTW, there's a bug when running ver 2.5.2 on OS X 10.7 Lion that results in only one of several selected files being deleted when Permanent Eraser is activated via the contextual menu service. I wrote to the dev, who responded the same day to say that a fix is coming in version 2.5.3.

I don't think it's fair to rate this product low purely for it's outdated inclusion and hyping of the 35-pass Gutmann method. Apple themselves make the same erroneous claims in Disk Utility, so they set the precedent. If Apple doesn't know any better, how can small developers be expected to?

In addition, this tool adds simplicity and convenience to what is more awkward and time consuming to accomplish via a combination of srm at the command line, Secure Empty Trash in the Finder, and Erase Free Space in Disk Utility. You can do the same things without this utility, but this utility makes it so much easier.

I understand your point. However, whoever specializes in a particular field should be aware of the particulars in that field. Otherwise apps like 1Password would be mediocre and clunky like Keychain Access.

I understand that Peter Gutmann NO LONGER recommends his 35 pass wipe on MODERN hard disks. His old 35 pass method was optimized for OLD hard disks NOT modern SATA Hard disks. It still amazes me that people still think his 35 pass method is better.

See Gutmann's paper on this:

or look at wikipedia:

If one prefers not to use the Gutmann Method, Permanent Eraser 2.5 also offers two other erasing options: a simple 1-pass method or the 7-pass DoD algorithm.

Edenwaith "Eraser 2.5 also offers two other erasing options: a simple 1-pass method or the 7-pass DoD algorithm"

In conclusion, using the 7-pass DoD method would be equivalent to OS-X's "Secure empty thrash"?

Edenwaith (developer)

That's correct. Apple's "Secure Empty Trash" uses the 7-pass DoD algorithm.

Only one issue-

I find that once launched, it erases so fast that I am unable to get to the Preferences before PE quits. Ands for me, that is very important.

When that is resolved, five stars!

Same problem here, only found through experimentation with large erasures that Prefs is actually greyed out while the app is in operation anyway. So still no way to interact with this feature. Agree with Harv's review right down the line.

I emailed the developer re my problem and he promptly replied.

Rather than blaming another or responding with smoke & mirrors, he acknowledged the issue & took full responsibility for the inconvenience, suggesting that:

"...the Preferences window can only be opened once a file (or the Trash) is in the process of being erased. When the Preferences window is open, it will suspend the erasing until the window has been closed. I recommend to start erasing a full Trash and then open the Preferences while the erasing has started.

This is certainly not an optimal way to open the Preferences, and I will look at a more elegant and user friendly solution to this problem."

Indeed I am pleased with support such as that!

Thank you to everyone who notified me about the annoying difficulty to open the Preference window. This problem has been corrected with Permanent Eraser 2.5.1.

From the developer's description:
"Once your data has been erased, it can no longer be read through traditional means."

But can it be read through *any* means? That is the question.

Installed just as directions specified - drug program icon into app folder. Then installed plug-in. Program works fine, but only by launching it. I can't get the plug-in to work through services, nor can I install the program icon into the menu bar. Is this a limitation with snow leopard?

To add Permanent Eraser to a Finder's toolbar, drag the Permanent Eraser application up to the Finder window's toolbar and hold it there for a couple of seconds and then let up on the mouse button.

If you are running Snow Leopard, the Install Plug-In script will install the Erase service into your home folder's Library/Services folder. Log out and log back in to refresh the Services. Once you select a file or folder in the Finder, right-click or select the Erase service from the Services menu.

The 'warning' is no longer coming up, as it did in v2.2.3.

Should we delete this preference file? - com.edenwaith.permanenteraser.plist

Yes, if the warning doesn't appear, delete the Permanent Eraser preference file (~/Library/Preferences/com.edenwaith.permanenteraser.plist) and that will reset any settings.
