    TYPE
          External 
    SYNTAX
	  [d:][path] DISKCOPY [sd: [td:]] [/1]
    OPTIONS
	  [d:][path]	 Specifies the drive letter and path that
                         contain the DISKCOPY command file.

                         sided disk.
    EXAMPLES
	  DISKCOPY A: B:
copies the disk in drive A onto the disk in drive B.
	  DISKCOPY A: A:
copies the disk in drive A to another disk that you will be 
prompted to insert in drive A.
	  DISKCOPY B:
copies the disk in drive B to the disk in the default drive.
	  DISKCOPY
copies the disk in the default drive to another disk that will be 
placed in the default drive.
    MESSAGES
	  Copy complete
The source disk has been copied onto the target disk.
	  Copy another (Y/N)?
Enter Y to make another copy; otherwise, enter N.
	  Copying x sectors per track, n side(s)
This message indicates whether one or two sides are being copied 
and whether eight or nine sectors are being copied.
	  Diskette/Drive not compatible
The destination disk or drive is different from the source disk 
or drive. You may be trying to copy a double-sided disk to a 
single-sided disk, for example.  Use the same type of disks and 
drives and try again.
	  Formatting while copying
The target disk is being formatted in the same format as the 
source disk.
	  Insert source diskette in drive x
	  Insert target diskette in drive y
Insert the appropriate disks in the correct drives.
	  Incompatible drive types
The first disk and drive are two-sided and the second drive or 
disk is one-sided.  Use the /1 option.
	  Make sure a diskette is inserted into
	  the drive and the door is closed
The drive door is open, or the drive is empty. Close the door or 
insert a disk and try again.
	  Source diskette bad or incompatible
There may be bad sectors in the source disk, or it may not be 
compatible with the drive. Check to make sure the disk is of the 
type that the drive accepts and try again, or try with a new 
disk.
	  Specified drive does not exist,
	  or is non-removable
The drive you specified is a hard disk or does not exist on your 
computer. Check the drive name and try again.
	  Target diskette may be unusable
There is an unrecoverable read, write, or verify error on the 
target disk.
	  Target diskette unusable
The target disk is dirty or damaged, or the drive is not able to 
read all the tracks. Change the disk and try again.
	  Target write protected
	  Correct, then strike any key
Insert another non-n-write-protected disk or remove the write-
protection tab; then press any key to continue.
	  Unrecoverable format error on target
	  Target diskette unusable
An unrecoverable error occurred; the target disk contains no 
usable data. Use a new disk and try again.
	  Unrecoverable read error on source
	  Track xx, side yy
Four unsuccessful attempts were made to read data at that 
location. DISKCOPY will continue; however, the copy may not be 
complete.
	  Unrecoverable verify error on target
	  Track xx, side yy
Four unsuccessful attempts were made to verify data at that 
location. DISKCOPY will continue; however, the copy may not be 
accurate.
	  Unrecoverable write error on target
	  Track xx, side yy
Four unsuccessful attempts were made to write data at that 
location. DISKCOPY will continue; however, the copy may not be 
complete.
    NOTE
     
     Version 1.0 does not work with double-sided drives. Later 
versions automatically check whether the source drive and disk 
are single- or double-sided, and make the copy accordingly. Later 
versions work with nine sectors per track. The drives used with 
DISKCOPY cannot be virtual disks, such as one created by using 
the SUBST command. In addition, do not use DISKCOPY when the JOIN 
command is in effect. DISKCOPY is not recommended for use with 
heavily used disks because it does not reduce fragmentation; use 
the COPY command with such disks instead.
