| Cause | Explanation | |-------|-------------| | | Pulling the drive out during a write operation corrupts the FTL (Flash Translation Layer). | | Bad block accumulation | Over time, the drive’s spare block count depletes, causing firmware panic. | | Power fluctuation | USB port voltage drops mid-operation, corrupting controller metadata. | | Physical cell degradation | TLC/QLC NAND cells fail to retain charge, leading to firmware checksum errors. | | Firmware mismatch | Attempting to update with the wrong tool bricks the controller into safe mode. |
