Solaris > Format floppy, UFS file system, fix bad blocks

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

rmformat –F quick /vol/dev/diskette0

rmformat –F long /dev/rdiskette

rmformat –F long /vol/dev/diskette0

Where,

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