A visit from the Shredder!

The Shredder!…and nope, it wasn’t the evil-yet-ineffectual, tin-foil clad villain of Teenage Mutant NinjaHero Turtles!

Still, there were plenty of fearsome-looking blades.

Disposing securely of old hard discs is an important part of our data hygiene. Each time we retire a server, the discs are securely wiped before they’re removed or re-purposed. If they fail, are out of warranty or are otherwise basically useless, they need to be disposed of properly. Having them shredded is by far the most reliable way of ensuring the discs are beyond use.

Booking a visit from a disc-shredding lorry is a convenient way of arranging this; we had one last week. As you can see from the photos, the shredding process is comprehensive. Hard discs are fed in by hand through a safety slot where they are then crushed and shredded. All the remains are small particles, no bigger than 20mm, from which it’s effectively impossible to retrieve data.

For security, and to provide an audit trail, the entire process is recorded on video. The particles themselves are returned to the disc shredding firm who send them on for recycling. We’re provided with a waste transfer notice and they confirm that nothing is sent to landfill, which is good to know.

Thanks to Bytemark’s Pete F for the photos!
