Data wiping

I’d like to wipe data on My Book 2TB hard drive. The LifeGuard Diagnostic software provides this function with “filing zero”. I wonder is it correspond to the DoD 5220.22-M US Standard (at least 3 passes)? To be sure all data are erased and can not be recovered.

If the Lifeguard procedure gives only one pass of the wipe, can I use a third party software to implement the DoD 5220.22-M method? Is it safe and not affect the normal drive function as well as recognizing it by Windows?

The DLG tool only does single pass. You can use whatever third party tool you want, it will not affect the drive’s use or performance. If you can’t find a tool to use, you can always run the write extended zeros option 2 or 3 times.
