My previous comments were not entirely accurate. Mireth tell me that Shredit X and Netshred X do indeed erase File Slack so BCWipe is not alone in this. To the best of my knowledge Disk Utility does not do this - but I am open to correction.

Oops! Evidently I am not allowed to post urls to the site. A Google search for "Mac File Slack" should bring up the relevant information for anyone who is interested.

The significant difference between this application and others - including Disk Utility - is that BCWipe erases File Slack whereas others do not. I am not in a position to comment on how significant a difference this is - but see for
more information.

I haven't downloaded the app but $40 for something that pretty much comes with OS X without the bells and whistles in Disk Utility?

Isn't the Guttmann method plenty with 35 overwrites, which Disk Utility can perform for free?

I guess someone who downloads the app should comment but don't forget that Disk Utility can already clear your information D.O.D "standard."

I agree it is too expensive. But it will allow you to wipe FREE SPACE on your mac Had disk. I do not believe the free utilities will allow you to do that.

P.S. Peter Gutmann does NOT recommend 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.

OK then, if Gutmann's 35 pass method is not secure enough for destroying data on a modern SATA hard disk, which method is better.

@Syzzygy -- The reason why Gutmann is not recommended for Modern Hard Disks is found in his paper:

http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html

Wikipedia has a nice summary:

"Most of the patterns in the Gutmann method were designed for older MFM/RLL encoded disks. Relatively modern drives no longer use these older encoding techniques, making many of the patterns specified by Gutmann superfluous".

See http://en.wikipedia.org/wiki/Gutmann_method

In other words many of the Gutmann passes do little to properly erase the data on Modern Hard disks.

Personally I would stick with the DoD 7 pass method included for free in OS X. (i.e. Use Secure Trash or srm command in the Mac OS X Terminal).

Of course, if you really want to make sure that the data is erased, I would put the hard drive through a Shredder designed to chew up hard disks.

You can use Diskutil in the OSX Terminal to wipe free space (diskutil secureErase freespace 2 /Volumes/Macintosh) does it...the number 2 = 7 pass wipe and "Macintosh" is the name of my HDD to wipe (clever naming, eh). Also, DiskUtility in your Utilities folder does the same thing but via a GUI (I use the Terminal version so I can run as Automator script and put to sleep when finished).

Prolly should mention if you don't include the "freespace" term it will wipe your entire hard drive so use with CAUTION.
