2.) How do they wipe a drive’s contents?
- Click the Settings icon, then click “Change PC settings.”
- Click Update and Recovery, followed by “Recovery.”
- Under the heading “Remove everything and reinstall Windows,” click “Get
started.”
- When prompted, select the option “Fully clean the drive.”

3.) How are Gauss and Oersted ratings applied?
- Degaussers are rated differently from how the media evaluates them, based on the
maximum magnetic field strength. This magnetic field is measured using the Gauss or
Lopez 2
Oersted formulas. Additionally, hard drives have a highly detectable magnetic property
known as coercivity that is also measured in oersteds.

4.) What length of time is required to degauss a drive?
- It largely relies on the degausser's size. For instance, a large, powerful degausser
may process material much more quickly, which will result in a quicker
processing time, whereas a small degausser may actually take longer. It actually
depends on how big it is, but if I had to guess, I'd say it may take anywhere from
5 seconds to a whole minute.

5.) Some companies offer degaussing services. What procedures do they use to ensure
secure practices?
- Companies employ overwriting, degaussing, encryption, and physical destruction
as security measures. This procedure overwrites the storage medium with new
data in a straightforward and secure manner. The magnetic field of a disk or drive
is eliminated during the degaussing process. This procedure is used in encryption
to protect data from unauthorized access. This procedure is used to physically
destroy the media by shredding or grinding it.
