What is Permanent Eraser?
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 Mac OS 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 nothing before Permanent Eraser finally unlinks it from the system. Once your data has been erased, it can no longer be read through traditional means.

Said about Permanent Eraser as an alternative
It deletes any file including ones from the trash. Even files that the OS is identifying as in use (when they are not) are wiped entirely with this software. The only reason I refrained from voting it as the best DBan alternative is that I don't know how it will behave with extremely large files, example, a full external Terabyte sized hard drive.
