I got a problem with my 8 GB Cruzer recently. I used UltraISO to create a bootable disk with Windows 7 setup on it, everything worked fine. Then I decided to reformat it, so I could use it in my car’s radio. The thing is it must be FAT16, else the radio won’t read it. I used a small program called Bootice to format is as FAT16, but due to its limitation, the created partition was only 4 gigs and the radio still couldn’t read it. The flash drive works fine on computers and a ps3.
The radio was able to read the flash drive before and I remember the partition was around 7.5 GB. The car is a Honda Civic 2007.
I tried to figure out where the problem lies, unfortunately without a success.
