DI (Disk Information)
Description: Displays technical information about a disk drive. Includes
device type, drive number, bytes per sector, sectors per
cluster, number of file allocation (FAT) tables, bad clusters,
etc.
Syntax: Version 4.0, 4.5: DI [(drive:)]
Parameters:
(drive:) The single-letter specifier (A:, B:, C:, etc.) for the drive
you want to process. Follow the letter with a colon. The
current drive is the default. If you are using a floppy disk
drive, you must have a formatted disk in the drive to receive
complete information.
Notes:
DI returns an encoded media descriptor value to describe the disk type. The
following table lists and defines the values that are valid:
Hex value Meaning
F0 1.4-MB 31/2-inch floppy disk
F8 Hard disk (all types)
F9 1.2-MB 51/4-inch floppy disk or 720-KB 31/2-inch floppy
disk
FD 360-KB 51/4-inch floppy disk
FE 160-KB 51/4-inch floppy disk
FF 320-KB 51/4-inch floppy disk
For the drive number, the utility returns 0 for drive A, 1 for drive B, and
so on.
