Reformat

My problem is as stated in previous post. I want to reformat my fat32 partions to get rid of windows 2000. I find no 'reformat' in the partions menu. I want to keep them as fat 32, so can install another OS. I  am a first time user of gparted, but just using the format fat32 in the partions menu does not do away with 2000. Since I loaded the gparted live cd my western digital diagnostic disk will not reconize it as a WD drive, so that I can reformat the drive. If there is a way to undo gparted and return the drives orginal format before installing gparted that would be alright also.
thanksfor the reply, I hope I have explained it a little better this time. I down loaded the live cd 3 days ago but didn't write the version on the cd.

Did not run from a os. Booted from the live cd.

I guess that I must try once again to explain my problem or question as mentioned in my posts.
HARDWARE DETECTION BY QPARTED IS NOT MY PROBLEM. It works fine but when I booted my machine with the live cd, and qparted was installed on the hard drive, it reads the partitions.
What I want to know is there a way to reformat the fat32 partitions that appear on the gparted screen that will remove the os windows 2000 pro, so that i have a blank fat32 partitions, using gparted???

Thanks, for the complement,(young man) by the way my birthday is 3-3-33, how old are you anyway? LOL. 
Thanks your 2nd sentence in your last post was the'how to' I needed. My problem is fixed.
Sorry about the Qparted, sometimes my arthritis isn't as bad as my eyesite.
I am just new to gparted not DOS or Windahs, but have switched to Ubuntu on my 5 puters. Had just cleared the partitions with a dos boot disk, when your post came in. You saved me some time, Thanks, I dont like to make mistakes.
Again THANKS!
