This is the definitive solution for "13fe USB Disk 50x" devices that are bricked.

| Do | Don't | |----|-------| | Always use "Safely Remove Hardware" | Pull the drive while a file is saving | | Keep backups on cloud or HDD | Store the only copy on a USB stick | | Eject before sleep/hibernation | Use the drive as an OS paging drive | | Test the drive every 6 months | Leave it plugged in 24/7 |

When these devices fail, it is rarely the NAND memory itself that has spontaneously failed; rather, it is the translation layer (firmware) on the controller that has become corrupted, severing the link between the USB interface and the stored data.
