When users plug in new components, the system may be able to automatically connect with them, install the right driver, and establish communication. Operating systems often include a library of common drivers and controllers. Controllers can also temporarily stop operations while the device is busy, and may shut down the mass storage device to allow the user to safely remove it. Signals from the user are sent through the mass storage controller to make the necessary changes. Users can select the individual files they want to transfer, copy, edit, or otherwise work with.

In all cases, the device holds data in a consistent and stable fashion that includes a file structure and various security measures. Manufacturers of mass storage devices may make downloads of their controllers freely available for customers.Īn external hard drive, a type of mass storage device.ĭevices used for mass storage can include internal and external hard drives, as well as equipment like flash drives, designed specifically for portability.
