Data Centers

How Google secures its data centers (photos)

Google tracks the location and status of each hard drive in its data centers.

If there is a problem with a hard drive, it's reformatted and retested. If the drive does not pass these tests it's then removed, and the data on the drive is overwritten and verified to make sure it contains no customer data.
