I have an unusual stuff here. I have plugged in my USB which is 8G of storage. And the gnome-disks utility can see that there are free space as shown bellow:

Free 7.8 space

But when I try to create a FAT32/NTFS partition, I get an error bellow : Error when creating partition

Error creating partition on /dev/sdb: Command-line `parted --align optimal --script "/dev/sdb" "mkpart primary ext2 1MiB 7750287359b"' exited with non-zero exit status 1: Error: The location 7750287359b is outside of the device /dev/sdb. (udisks-error-quark, 0)

More troubling is the fact that when I use gparted to try to resize th thumb drive, I get something like this where gparted can only see that my USB drive has 1.8G of space: only 1.8G of space

So what can I do to reclaim my space ?


I ended up wiping the whole USB with dd : sudo dd if=/dev/zero of=/dev/sdb bs=1M and deleted all with sudo gdisk /dev/sdb ( = launch gdisk, then type x, then type e, then type w to save your changes).
