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. Write-Protect Switch To allow writing to the diskette, slide the switch so the write-protect window is covered. To prevent writing to the diskette, slide the switch so the write-protect window is open. 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. 32 Storage Devices
