Ubuntu – USB stick shows up as two drives!

fdiskgpartedusbusb-drive

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.:)

Best Answer

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.
