Here is a good puzzler. I got a second ATAPI disk in my machine that I
was able to partition with fdisk, but cannot mkfs it. It says that the
device is already mounted but when I try to umount it, it says it is not
mounted. the blkid command I ran on the device contradicts with what df
tells me. You can see the commands and outputs below.
I could try booting from a live cd and mkfs the drive, but I am very
curious why this is happening. I have never had this happen to me before.

You may have a stale record in /etc/mtab. Make sure /dev/hda1 *really*
is not mounted, then remove /dev/hda1 record from /etc/mtab and try
mke2fs again.
