Hi, my laptop seems to decide to turn certain USBs into read-only file systems, even overnight, while I was downloading a file straight onto a USB and paused it, the next time I tried to use it, the USB was read-only.
I tried opening my file browser in root, but it's still read-only.

If it helps, the two USBs are a Sandisk 16GB Cruzer and an Integral 4GB mini USB.
