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.

It would be more secure to just melt the drives down. With a melting temperature of just under 1300 degrees it would not be hard ether.
I dont' know if this is a relevant question to ask.I was just curious in the youtube video. Inside the data center, why are the personnel wearing headphones/earphones? is this a standard to all data centers.
Our data is safe from others, What about google? How it can ensure that GOOGLE wont use/keep/read our pesonal/finance datas?
Once upon a time I used to be in the business of recovering data from old hard drives. Given the equipment I had to work with, infomation on a hard drive that had been overwritten was very easy to recover. The only hard drives that were not able to be recovered were the ones that had been shredded.
Yeah. Saw the pic where they (i think) fed the hdd into a shredding machine. How we all wish we had them in our office or homes. Hehehe. Just a funny side statement but good work GOOGLE for keeping our data's secure.
Those are hearing protecting headsets. With hundreds or even thousands of servers in a large room, the noise level from all the fans can be very loud.
