Diskcopy Ü
ßßßßßßßßß
Copy the contents of a floppy disk to a second floppy.
Syntax: DISKCOPY [d: [d:]] [/A] [/M] [/I] [/O] [/1] [/X] [/D] [/V]
d: The drive letter for a floppy disk. If only one drive letter is
given, assume the working drive (if a floppy drive.) If no drive
letters are given, assume both are the working drive (if a floppy).
If both drives are the same, diskcopy will read one floppy at a
time, and you may need to swap floppies.
/A Gives an audible warning for user actions.
/M Only use memory for disk copy.
/I Shows memory usage.
/O Overwrite destination if it already exists (image files only).
/X Always automatically exit (don't ask about another copy).
/D Don't ask to verify if the disk is in the drive.
/1 Copy the first side only, even if double-side.
/V Verify that the data is copied correctly.
Notes:
The /X switch makes sure the program always exits. You will most
likely notice this at the end of the program. If you use this switch
the program will no longer ask you whether you want another copy of
the disk or whether you want another copy of the disk.
The /M switch uses memory to copy disks, meaning it uses EMS, XMS, or
buffers. For more help with memory, see the Mem command.
When creating image files on disks, you can use the /O option when you
want to make an image file of a floppy disk and a file with that name
already exists, the program refuses to overwrite the file. With
this option you can change this behavior and force an overwrite of
existing files.
More Information:
Image files
Image files are files that contain the contents of a floppy disk in raw
format.
The main advatage of image files is that one can save the contents of a
floppy on a different medium, like a CD-ROM or a hard disk and recreate
the disk only when you need it.
Image files allso make it possible to distribute image files through the
Internet.
Rawrite compatibility
The image files supported by diskcopy are now also compatible with
rawrite image files (commonly used with Linux distributions and the
FreeDOS distribution).
Diskcopy can thus be used to create the images for use with rawrite.
There is only one thing to notice here. Because diskcopy uses DOS to find
out the disk sizes for the diskettes it can only work with FAT. Reading
from non DOS disks is impossible.
On the other hand writing to a disk formatted to use FAT is possible no
matter what the image file itself contains. If there is an other file
system on the diskette format a: /q can be use before writing an image
file to the diskette.
