The rmformat utility is used to format, label, partition, and perform other miscellaneous functions on removable, rewritable media that include floppy drives, IOMEGA Zip/Jaz products, USB mass strorage and the PCMCIA memory and ata cards.

The mkfs utility constructs a file system on the device (format i.e. create file system).

Format floppy:
1) Use the command rmformat to format the floppy disk:

rmformat –F quick /dev/rdiskette

OR

rmformat –F quick /vol/dev/diskette0

OR

rmformat –F long /dev/rdiskette

OR

rmformat –F long /vol/dev/diskette0

Where,

  • -F long : Formatting with media verification
  • -F quick : Formatting w/o media verification
