- Unsafe removal: Yanking the drive out while writing data (especially during a format or partition operation).
- Power fluctuation: A sudden voltage drop or surge while the drive was active.
- Failed firmware update: Attempting to flash new firmware that was incompatible.
- Physical wear: The NAND cells degraded, and the controller’s translation layer crashed.
