Securely Wiping Hard Drives

[ChAoTiCpInOy]

Is the Mac OS X Disk Utility as secure as utilities such as DBAN and the like?

Open whatever MAC OSX calls notepad. And type 0100010011011111101 all randomly until HD is full.

From wikipedia: "Disk Utility accomplishes the erase feature by creating large sparse image files in a preset directory. It then deletes them with the srm tool (secure remove) and an overwrite pattern of your choice."

and

"Some users have reported that they have had no success using this process. These users have been able to reclaim 100% of their free space by shutting down their computers, rebooting them, then emptying the trash. The sparse image should, after a reboot, be located in a recovered files folder in the trash. Deleting the file will recover all lost disk space."

Probably not as secure as DBAN's most secure options.

Nah, just loop this instead.
