I was given a free 1GB USB at an event a few months ago - however, when I plug it in to my Ubuntu laptop, the USB shows up as two drives (/dev/sdb and /dev/sdc). I have checked it isn't just partitions - it isn't, since GParted also shows the USB as two drives.

Is it possible to merge the two drives using fdisk or GParted?

The USB was free, so I really don't care if the thing ends up broken. I just want to experiment and see if it is possible to merge the two drives and have a working 1 GB USB.:)

You just need to remove a partition. You can use GPART for this.

Here is a guide to help you with that, https://askubuntu.com/questions/824880/how-to-remove-a-partition-on-a-hard-disk#:~:text=If%20you%20right%2Dclick%20on,the%20partition%20as%20you%20wish.

Suggest you use Gparted to delete the FAT12 and FAT16 partitions and then create one FAT32 partition. Pick your USB device from the spin box at upper right http://www.zimagez.com/zimage/screenshot-01262014-025522pm.php then delete the old partitions http://www.zimagez.com/zimage/screenshot-01262014-025931pm.php by right-clicking on each partition and selecting Delete. Then reformat it as the current preferred FAT32 partition type for maximum utility.
