This is a Boolean type of property that tells us whether the drive is ready or not. Because some the drive allocated for the device like removable, CD ROM. But it will be enabled when the device is plugged into the device.
The total size of the drive can be manipulated based on the device state. If it is a system drive then it will be ready when the OS is running.
