External drive - wrong size af free space
I have an external usb drive with a 20 Go size formatted in fat32. My computer is a linux fedora core 3.
My problem is that only 11 Go are used (I can see it with the 'du' command ). I have verified the used space under windows also: it's the same, 11 Go. Normally the free space should be 9 Go.... But linux detects only 600 Mo of free space. So I can't write big files on the drive with linux. Everything is ok with Windows which can use all the available space.
I have done a dosfsck -a /dev/sda1 but it doesn't changed anything.
What can I do to recover all the free space with linux ?
