My mother has a radio that can play MP3s on a USB key. I noticed something strange. When I format it with diskpart from Windows 8.1 my mother's radio has no problems playing the MP3s on a USB key, but if I do the same with fdisk, the radio just says that there are no files on the USB key.
So, this is what I did to make sure, I was not just imagining things:
First, I did a quick delete of all the files in the USB key with:
sudo dd if=/dev/zero of=/dev/sdb bs=4M count=1
Well, that deletes the MBR, partition table thoroughly. (I know I do not need to delete 4M to delete everything, but I was not sure about gpt and stuff.)
I formatted the USB key with Windows diskpart
diskpart list disk select disk 1 clean create partition primary select partition 1 active format fs=fat32 quick exit
It works perfectly on my mother's radio!
Now I format it with fdisk after deleting everything like above with
sudo fdisk /dev/sdb n p (return 3x) a w sudo mkfs.vfat -F 32 /dev/sdb1
Now for some reason it doesn't work!
And here is the information when formatted with diskpart:
Please tell me if there is a way to make the USB key work on my mother's radio without having to boot up Windows all the time. Thanks!
