Somehow I messed up and accidentally made my usb stick into a read only file system. I have tried a bunch of things to delete the files, including the basic (
rm -f myfile) and attempting to allow writing (
sudo chmod +w myfile) and then deleting, but none of this seems to work. Any ideas on what I can do. I don't have anything on the usb stick that I need, but I don't want to throw away an otherwise perfectly good piece of equipment.
How can I make it work? Am I going about this completely the wrong way?
