The three main methods

Wiping (overwriting data) suits drives that will be reused or resold. Degaussing scrambles magnetic media that won't be reused. Physical shredding is for drives that must never be readable again. Which one applies depends on the device and what happens to it afterward.

SSDs vs traditional hard drives

For hard drive shredding vs degaussing, solid-state drives don't behave the same way as spinning hard drives when it comes to data destruction — some wiping methods that work well for one don't apply cleanly to the other. Mention the drive type so the right method gets recommended.

Documentation for businesses

For hard drive shredding vs degaussing, documentation covering what was destroyed and how may be available depending on the service type and what's agreed in advance. Raise this requirement at the start of the conversation, since it shapes which method and process gets used.

How do I prepare hard drives?

Back up any data you want to keep, and mention whether the drive is functional or physically damaged.

What is degaussing?

Using a strong magnetic field to scramble data on magnetic media, suited to drives that won't be reused afterward.
