[vox-tech] HD Repartition frustration

[Donald Greg McGahan]

I have a 100Gb Seagate 2.5 inch hard drive that currently has a ntfs
partition, and extended partition with a fat32 partition within it. I
wanted to repartition it to a single fat32 partition. I removed it from
it's (third party) external enclosure and installed it as an secondary
IDE slave (adapter) in my AMD K7 (1.33MHz) Ubuntu OS box.
I cannot seem to accomplish this task?!?
I've tired deleting all of the partitions and then writing but no joy.
I've been fussing with this on and off for a few days and thought I get
some help.
Here is what I'm doing.
I pop open a terminal window and 

fdisk /dev/hdd (i've tried both with sudo and sudo su)

then

Command (m for help): p

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.
dig at vill:~$ sudo fdisk /dev/hdd

The number of cylinders for this disk is set to 12161.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
