Okay, just the other day, I was trying to install Ubuntu on an 8GB flash drive. Near the end of the installation process, the install failed. The flash drive is now entirely dysfunctional.
At first, the flash drive would mount on Windows, but not on Ubuntu. In Ubuntu, by Disk Utility, GParted, and Terminal, I was not able to format the flash drive, it only returned errors. When I took it to Windows, it will mount it, but I can't move any files because it will return an error that the flash drive is write protected. Same thing happens when I try to format it, both by the formatting tool and Command Prompt. I tried another format tool I found online after searching elsewhere for this problem, but the program crashed, and now Windows won't even mount the flash drive, saying that I need to format it.
