To prevent data from being written to a disk, ... have a write-protect tab that you can slide ... to ... the disk. With the tab slid back so you can see through the window, the disk is protected.
High density Double density

The amount of data each disk can store depends on:
- the disk's physical size;
- the number of sides on which the data is stored;
- its density (high density or double density); and
- how the disk is formatted.
All things being equal which floppy disk is able to store more data? - Double-sided high-density or Double-sided double-density.
