So i have an 8gb usb flash drive and when i try to create a partition in it on Disks but it says: "Error creating partition on /dev/SDB: Failed to meet partition size on device '/dev/SDB'(u disks-error-quack-error-quack, 0).Now the thing is when i go on GParted it says that my usb is 965,80 mb but its 8gb . I dont know what to do . Also when i try to format it using terminal commands nothing happens.Nothing changes . I type : "sudo mkfs.vfat /dev/sdb1" , the command doesn't give me an error but it doesn't do anything. Please i need help. I think there is a problem and the os things its a 1gb usb or i changed something accidentally and I don't know how to fix it .

  • Start by showing us the screenshot from GParted, and the output of sudo fdisk -l when the device is connected

  • That sounds a lot more like the USB stick has died and is broken - that's a hardware failure in the stick and not something we can fix.

  • I tested it by adding files in it plugging it out and in the computer . Nothing happened on the computer but the file was still there on my phone.

Try to erase the MBR of your USB disk:
