MPI 40 Series - Write Protected Diskette

2.7.3 Write Protected Diskette
Most diskettes today incorporate a write protect feature so your
system cannot accidentally write over or destroy valuable infor-
mation contained on your diskette when the write protect feature is
activated.
The write protect feature is activated by the hole in the diskette
as shown in figure 2-5. When the hole is opened it is write
protected, when the hole is covered writing is allowed. For write
enable, the hole is closed by placing a tab over the front of the
hole and folding over the tab to cover the rear of the hole.
By removing the tab the diskette can once again be write protected.
IBM diskettes are not manufactured with a write protect hole. To
write protect one of these diskette, a hole must be punched out as
shown in figure 2-6.
