Amstrad DDI-1 manual Open Closed

When the hole is closed, data can be 'written' onto the disc by the computer. When the hole is open however, the disc will not allow data to be written onto it, thus enabling you to avoid accidental erasure of valuable programs.

Various compact floppy disc manufacturers employ different mechanisms for opening and closing the Write Protect hole. The operation may be carried out on the Amsoft CF-2 compact floppy disc as follows:

To open the Write Protect hole, slide the small shutter located at the left hand corner of the disc, and the hole will be opened, See Figure 8(a).
