Having been using them a long time, when they are about to die, they normally become read only - but it does sound like some kind of electrical or mechanical fault.Yes, it is a misswriting, sure it was "'disk removed without ejecting".
But I didn't remove the usb flash drive!!!
But for some reason Raspberry gave just such a message. Moreover, on a PC these flash drives worked for a long time and without problems.
Are you using the official power supply, or a (phone) charger (which doesn't give a constant voltage)?
