Make sure you are using the proper identifier for the device on the
command line.  On a modern installation, it should look something
like this:

	fdisk /dev/sdb

If you aren't sure, then check the latter part of the output from
dmesg after attaching your reader and/or inserting the card into it.

Also, be sure that you are using 'w' to write the partition table
and not simply 'q' for quit -- the latter will leave the partition
table unaltered, as if you had never run fdisk at all.

The link someone posted elsewhere in the thread should cover the
mechanics of actually selecting the partition type.  You probably
also want to make sure you are using a "primary" partition.

fdisk does its job, but it neither helps you much nor does it get in
your way.  It is a sharp, pointy tool that is perfectly happy to give
you enough rope to shoot yourself in the foot, so be careful! :-)
