In the latest version of Disk Manager software, there is a write protect feature. When you bring up the Disk Manager program, in the upper left quadrant of the window you will see the words "Device Write Protect." If the write protect is engaged, the lettering will be blue and you will see a button depressed. But when the write protect feature is off, the lettering is black and there is no button visible.
