: Scanning the NAND memory to identify and isolate physically damaged areas (bad blocks), allowing the rest of the drive to function. Capacity Restoration
However, because it is frequently paired with cheaper or "downgrade" memory modules, the drive's internal translation layer (the flash translation layer, or FTL) is highly susceptible to corruption over time. When the controller loses communication with its firmware or encounters an unmanageable cascade of bad sectors, it locks the drive into a safety state to prevent physical damage. This is when a standard user notices that their flash drive has suddenly become unusable. 2. Pre-Requisites: Hardware Diagnostics with ChipGenius | Feature | SM3271AD | SM3257EN | SM3268P
