You ave created an extended partition.  Now you need to create a logical
partition with that.

On one of my systems I have:
magni:~# fdisk -l
<snip>
   Device Boot      Start         End      Blocks   Id  System
   /dev/hda1               1          39       19624+  83  Linux
   /dev/hda2              40         535      249984   82  Linux swap / Solaris
   /dev/hda3             536       26205    12937680    5  Extended
   /dev/hda5             536        2519      999904+  83  Linux
   /dev/hda6            2520        4503      999904+  83  Linux
   /dev/hda7            4504        6487      999904+  83  Linux
   /dev/hda8            6488       26205     9937840+  83  Linux

Partitions 1 and 2 are primary, 4 is the exteneded space, and partitions
5 - 8 are logical partitions.

Working from memory you need to do something like:
        * fdisk /dev/sda
        * "n" to create a new patition
        * "l" for logical
        * <return> (to start at the begining of the extended partition space)
        * <return> (to fill to the end of the extended partition space)
        * "w"
        * "q"
Now use /dev/sda5 and it should work happily.

Yours Tony
