We have to do this ourselves in the government for every decommissioned server/appliance/end user device. We have to fill out paperwork for every single storage drive we destroy, and we can only destroy them using approved destruction tools (e.g. specific degaussers, drive shredders/crushers, etc). Appliances are usually the worst, though. It can be tricky sometimes finding all the writable memory in things like switches and routers.
