Comments

The caller of the IOCTL_DISK_FORMAT_TRACK request indicates the disk size and number of bytes per sector, along with other formatting information, by specifying one of these values in the MediaType member of the FORMAT_PARAMETERS structure.

Removable disks include zip drivers, jaz drives, magneto-optical (MO) drives, and LS-120 floppies as well as regular floppies.
