    I can't format a certain floppy


    I have this floppy that just won't format.
    Code:
    ubuntu@ubuntu:~$ mkfs -t ext3 /dev/sdb 1440
    mke2fs 1.40.2 (12-Jul-2007)
    /dev/sdb is entire device, not just one partition!
    Proceed anyway? (y,n) y
    /dev/sdb is mounted; will not make a filesystem here!
    Code:
    ubuntu@ubuntu:~$ sudo fdisk -l
    
    Disk /dev/sda: 160.0 GB, 160041885696 bytes
    255 heads, 63 sectors/track, 19457 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0xcab10bee
    
       Device Boot      Start         End      Blocks   Id  System

    Disk /dev/sdb: 1 MB, 1474560 bytes
    1 heads, 3 sectors/track, 960 cylinders

    This doesn't look like a partition table
    Probably you selected the wrong device.

    I didn't think /dev/sdb was a floppy drive. Could explain
    the problem more fully?

    I have a bunch of floppies from now to maybe 1993. They're old!

    I've been using a Windows OS in order to reformat them, which gets annoying. I read them via an external usb floppy drive. And I guess the disks get mounted from /dev/sdb to /media/disk.

    Thing is, formatting /dev/sdb doesn't seem to work.
    I don't know why.

    Check the output of df command and make sure that Floppy should not be mounted because its not possible to format mounted devices. Execute umount command to unmount it.
    It is amazing what you can accomplish if you do not care who gets the credit.
