Basic Usage

To copy a disk image from a floppy drive, you use the command mcat followed by the drive identifier. This operation reads the entire disk image from the specified floppy drive and outputs it to the standard output (usually the terminal or a file) −

mcat a:

This command reads the disk image from the floppy drive identified as a:. The contents of the disk image are displayed in the terminal. If you want to save this output to a file, you can redirect it using the > operator.

mcat a: > output.img

In this example, the command reads the disk image from the floppy drive a: and saves it to a file named output.img. This file can then be used for backup purposes or transferred to another system.

Writing a Disk Image

To write a disk image to a floppy drive, use the -w option. This operation takes a disk image file and writes its contents to the specified floppy drive −

mcat -w a: disk_image.img

This command writes the contents of the file disk_image.img to the floppy drive a:. The -w option specifies that mcat should perform a write operation. This is useful when you want to create a bootable floppy disk or restore a previous backup.
