DISKCP(C) XENIX System V DISKCP(C)
Name
diskcp, diskcmp - Copies, compares floppy disks.
Syntax
diskcp[-f][-d][-s][-48ds9][-96ds9][-96ds15][-135ds9][-
135ds18]
diskcmp[-d][-s][-48ds9][-96ds9][-96ds15][-135ds9][-135ds18]
Description
diskcp is used to make an image (exact copy) of a source
floppy disk on a target floppy disk. On machines with one
floppy drive diskcp temporarily transfers the image to the
hard disk until a blank ``target'' floppy is inserted into
the floppy drive. On machines with two floppy drives diskcp
immediately places the image of the source floppy directly
on the target floppy.
The options are:
-f Format the target floppy disk before the image is
copied (diskcp only).
-d The computer has dual floppy drives. diskcp copies the
image directly onto the target floppy.
-s Uses sum(C) to compare the contents of the source and
target floppies; gives an error message if the two do
not match.
-48ds9
This setting is for low density 48tpi (360K) floppies.
It is the default setting.
-96ds9
This setting is for medium density 96tpi (720K)
floppies.
-96ds15
This setting is for high density 96tpi (1200K)
floppies.
-135ds9
This setting is for low density 135tpi (720K) 3.5 inch
floppies.
-135ds18
This setting is for high density 135tpi (1440K) 3.5
inch floppies.

When using the -96ds9 and -96ds15 options of diskcp, if the
first target disk is unformatted, the program will note it,
format it and make the copy. If another copy is requested
and another unformatted target disk is inserted, diskcp
exits with a ``System Error.'' Quit, format the floppy, and
reinvoke diskcp to make another copy.
diskcmp functions similarly to diskcp. It compares the
contents of one floppy disk with the contents of a second
floppy disk using the cmp utility.
Examples
To make a copy of a floppy, place the source floppy in the
drive and type:
diskcp
When diskcp is finished copying to the hard disk, it prompts
you to insert the target floppy in the drive. If you
specify the -f flag when you invoke diskcp , the program
formats the target floppy. When the copy is finished,
diskcp prompts if you would like to make another copy of the
same source disk. If you enter `n', it prompts if you would
like to copy another source disk.
Specify the -d flag on the command line if you have two
floppy drives:
diskcp-d
Notes
If diskcp encounters a write error while copying the source
image to the target disk, it formats the disk and tries to
write the source image again. This happens most often when
an unformatted floppy is used and the -f flag is not
specified.
