You can try restoring the USB drive to a standard format. There is a utility called mkusb
. Look at this link. Add the ppa, update apt and then sudo apt install mkusb
and when done, run mkusb
.
Step by step instructions. Run these commands:
sudo add-apt-repository ppa:mkusb/ppa
sudo apt-get update
sudo apt-get install mkusb
mkusb
and select option d see below:
if prompted for root password, enter it. Follow the insturctions on the screen:
and then select the Restore to a Standard Storage Device option (WARNING: you will loose all your data on the USB drive):
That should do it.
dmesg -w
when you plug the usbdmesg
shows the kernel messages.dmesg -w
leaves these open and live updates. What it might help you is to disconnect the USB, typedmesg -w
and then connect the USB. You will see new messages appearing related to your USB and you might see an error message if the device is damaged. Ubuntu configuration often states that if there are errors reading a system, is mounted read only and this is what I was trying to figure out. If you don't mind losing the information in the drive, reformatting it may help. Have a look atfdisk
,gparted
or others.
