Disc Utility refuses to format usb to fat32

[NPhillips]

I get this every time I need to format the usb, I can do it perfectly fine on my cousin's computer, but here it always greys out and prevents it.. I need it to be fat32 as my wii can only read that type of format..

Need some additional pertinent information that you did not supply:

1. What exact Mac model do you have?

2. What exact Mac OS are you using?

You should be able to format a device as either MS-DOS (FAT; = FAT32), or ExFAT. Here is how to do it:

1. Launch Disk Utility, and select the USB drive at the "top" level.

2. Click on Erase.

3. On the pop-up screen that appears, click on the arrow on the right side of where it says "Format", and select "MS-DOS (FAT)".

4. Also on that pop-up screen, click on the arrow to the right where it says "Scheme", and select "Mater Boot Record".

5. Click on "Erase" on that pop-up window.

Disk Utility will then Erase and Format the drive as MS-DOS (FAT), ie, FAT32.

I have needed to go through this exact procedure in order to format a 32 gig Flash Drive for use on a slightly older LG TV, on which I have copied movies to. It works flawlessly.
