I have been using a USB Thumbdrive on my pi 3 for many years now, and I see that it is busted. I can no longer modify anything in it anymore. It got write-protected status on all files. I tried format it on a Windows Machine, but it also said it is write-protected.
Anyway, I got all data from the USB Thumbdrive already, and then I removed the USB Thumbdrive, but then I see that DietPi still has a mounting directory for the thumbdrive in /mnt so I decided to go to DietPi-Drive_Manager to remove it.
But when I access the drive manager, all I got is a black blank screen and nothing else. If I press any key on keyboard, I got those weird character codes like in older programs. After I hit Ctrl+C, I have to wait for about a minute before DietPi becomes responsive and goes back to the terminal screen.
In this case, where can I tell DietPi to remove that directory? Is there a manual method instead?
