I have a 16GB flash drive that I have used to install SUSE linux on multiple computers, but now I want to use it for the new update image. The trouble is however, that no disk management tool I have sees the EXT4 partition (4.2GB) that is on the drive, not even the Linux tool. when I plug it in to a linux computer it sees it as a 4.2GB usable drive, but when I use the disk manager it appears as 14.8GB of unpartitioned space. When I plug it into a windows machine it tells me to format it but it isn't able to format it.
The first time around I deleted it with a DOS boot floppy but even dos doesn't see any partitions now.
