I AM NOT RESPONSIBLE FOR ANY MISUSE OF THIS FILE OR DAMAGE DONE TO YOUR HARD DRIVE!
1.download the fat32format from here
2.extract to some where easy to find like c:\ or d:\
3.run cmd (start>search bar>run>cmd)
4.and put this c:\fat32format.exe f:
C is the drive you put fat32format in and f is the drive you want to format to FAT32
5.when it asks you to format, press Y and enter
6.it should finish in few minutes
The cmd may not show any progress and stay like a frozen state.
This is what happened to me so just wait patiently.
