This is a video of a functional Toshiba laptop drive. Using a macro lens, we are able to see what happens when you read or write data to or from a hard drive. You can also see how the hard drive parks the heads off the disks when the power is shut off. This is to protect the hard drive from shocks during transportation.
It’s my first one of these videos so you can see my reflection in a couple of places, when I lean over to send different commands to the drive.
