If the drive listed is the one that the device is currently using, then yes, you can replace it with just about any SATA drive but there is usually more to it than that. Where is the OS located for this device and how is the drive formatted? If the OS is not stored on the drive and has the ability to both partition and format the new drive then you are good to go. If not, then you may need to image the existing drive to the new one if the existing drive is still working. If the existing drive is dead, you may have issues there. Some devices (like my cable DVR) will detect a new drive and ask for permission to format it but the only way to know if it can do that would be to either get a full manual for the device or to plug a new drive in and power it up to see what happens. In order to add a drive, you would need an open SATA port on the system board.
