So, today I was trying to format my Patriot Supersonic Mega 256GB FDD, in Gparted on Linux, when Gparted suddenly reported that the drive was unavailable while formatting a partition. Unplugging/replugging did nothing, Linux couldn't see it, either in Gparted, a file manager, or terminal. In Windows 10, it does register a driver, but diskpart gives the error "Virtual disk service error: There is no media in the device" when attempting to run the 'clean' command. In Device Management it registers as "13FE USB DISK 50X USB Device". This is not the correct name, it used to be different before.
I'm not even sure what caused this. How can I determine if the firmware controller is corrupt? I don't even know where to begin looking. I've had this less than a year and it has worked fine until now. Other USB devices don't have this issue for me. But maybe my USB ports are going bad? Unlikely, I think. If it can't be recovered then I will see if Patriot will send a warranty replacement.
