Flash Drive

I'm using mac most of the time, but I have a small pc laptop. So, my flash drives are automatically formatted to mac os journaled. I tried to reformat it into FAT32 but it doesn't work...When I plug in into my pc, it only says removable disks and asked me to format it...After I formatted my flash drive, it will create a 200mb partition on my thumb drive...

Any solution?

It seems like you already know the answer to this.

No..I mean...how to format it back the whole drive back to FAT32...cause when I'm using disk utility it will show different kind of format for a drive...

ex: 8 GB Kingston - the format is mac os journaled
Untitled - the format is FAT32

Even if I format the whole drive...only the untitled part is becoming FAT32...
I need the whole capacity of my drive available for both my pc and mac...cause I need it for uni...

Have you tried formatting it on a Windows machine?

On a Windows machine try using Disk Management (right-click My Computer, choose manage, and then click Disk management on the left side of the resulting window). Hopefully you can figure it out from there.
