Write Protecting Diskettes
It is possible to accidentally format a diskette or unintentionally write data to it. Important
information can be written over or lost. For this reason, it is a good idea to write protect
important diskettes. You can read data from a write-protected diskette, but you cannot
erase or change the data.
Most 3.5-inch diskettes have a write-protect switch that can be used to prevent data from
being written to or erased from the diskette. If a 3.5-inch diskette does not have a
write-protect switch, it is permanently write protected.
The write-protect switch is located on the back of 3.5-inch diskettes.

Formatting Diskettes
You can buy diskettes either formatted or unformatted. Formatted diskettes are ready to
use; unformatted diskettes must be formatted by your operating system before you can use
them. The format operation checks a diskette for defects and prepares it for storing data. If
data is already stored on the diskette, the format operation writes over it, and the data is
lost.
