If you're running a "standard" Fedora 14, somewhere in your "Applications" menu (probably in the "System" section) you should find the
gparted command. (There may, in fact, be a "Search" function in the Application menu. If so, just search for the
gparted command.) When you run it (and after you enter your "root" password), you should get a screen that (by default) will show the partitions on your first hard drive. In the upper, right, part of the screen is a drop-down window that you can use to find other drives. (They are called "sda," "sdb," etc. If you want to know why "hda" became "sda," just ask. But expect "jargon" as an answer.) Anyhow, one of the drives
should, I guess, have a single partition and be the one you want to reformat. (If it's not obvious which drive is the one you're looking for, close
gparted, unplug the drive, and restart
gparted. The drive that's not there is the one you're interested in formatting. Plug it back in, and press the control-R key combination to have
gparted refresh its device information list. Then select the device, and highlight the partition you want to format.
Once you've got the correct partition highlighted, select the "Format to" item under the "Partition" item in the main menu. That should pop up a list of format options, from which you should select "fat32." You will - of course - be warned that reformatting the partition will destroy all data in that partition - which is, of course, obvious, but a CYA that the developers feel they need to put in. Anyhow, after you accept the warning, the "check mark" at the right end of the menu under the main menu should turn green. Click on that (now green) check mark, and the partition will be reformatted. (If you
don't press the check-mark, nothing will be done to the drive.)
By the way, before you push the check-mark, note the "Label" item, also under the "Partition" main-menu. If you click that, you can add a label to your drive.
Hope this helps.
Good luck.
P.S.: If
gparted is not installed, use the "Add software" function to add it to your system.
