2.7 Disk Management Commands:

DISKCOPY

Type: External

Syntax: DISKCOPY [d:] [d:][/1][/V][/M]

Purpose: Makes an exact copy of a diskette.

Discussion

This command is used only for copying diskettes, not hard disks.

The first drive you specify is the drive for the source diskette. The second is the drive for the target diskette. DISKCOPY checks to determine if the disk in the target drive has been previously formatted. If not, DISKCOPY will format it before it starts the copy (except in early versions of DOS).

If the target drive is the same as the source drive (or if you do not enter a drive designator), the copying will be done using one drive. The program will prompt you when to insert each diskette.

Options

/1 - Copies only the first side of the diskette, even if the target diskette is double sided.

/V - Verifies that the source data was copied correctly onto the destination drive. Selecting this option will slow down the copying process.

/M - Forces DISKCOPY to use only conventional memory for interim storage during the copy procedure. Normally, DISKCOPY uses the hard disk for this purpose. (New with DOS Version 6.)

After copying, the program will display

Disk copy OK

Copy another (Y/N)?__

If you press the letter Y key, you will be prompted to insert another disk to copy using the same parameters. Press the letter N key to terminate DISKCOPY.

Example

To copy the contents of the disk in drive A to the disk in drive C (erasing any data already on the disk), enter diskcopy a: c:

LABEL

Type: External

Syntax: LABEL [d:][volume label]

Purpose: Creates or changes or deletes a volume label for a disk.

Discussion

A volume label may consist of up to eleven characters (the same characters that are legal for a file name). If you enter an erroneous volume label, the error message Invalid volume label appears, and the system prompts for a re-entry.

If you use this command without entering a volume label, the program displays

Input volume label - Up to 11 characters.

Press ENTER only to delete label.

Enter a volume label, or press the Enter key to delete the current volume label. To display the current label, use either the DIR or VOL command.

Example

To create the label TESTLABEL on the diskette in drive B, enter label b:testlabel

VOL (Volume)

Type: Internal

Syntax: VOL [d:]

Purpose: Displays a disk’s volume label.

Discussion

The VOL command is used to display the volume label. It is not used to add or change the volume label on a disk. For information on how to create, change, or delete the volume label, refer to the LABEL command.

Example

To display the volume label for the disk in drive A, enter vol a: The program displays:

Volume in drive A is (label)

If the designated disk does not have a volume label, the program displays:

Volume in drive A has no label
