Someone's writing raw output to disk.  There is no filesystem, just raw
data.  How did you create the disk in the first place?

To read, try:

   $ dd if=/dev/fd0 of=somefile bs=1024 count=1440

...replacing "somefile" with appropriate path and filename.

...and then access your file with standard tools.  You'll probably find
that it's filled with ASCII nulls (\000) following some point.  I'm not
sure of good methods for pulling out the data from here, but you can
probably muck around with tools to get a good approximation.

What did you expect to find on the disk?
