If you own a drive with this controller:
| Scenario | Description | |----------|-------------| | | The controller has no valid firmware or partition table loaded. Must run Alcor MP Tool to initialize NAND and create a standard FAT32/exFAT volume. | | Failed firmware upgrade | A corrupted or interrupted mass production process left the controller in recovery mode. | | Manual recovery mode | Shorting specific NAND pins or jumping the controller’s test point forces UFDISK enumeration for low-level repair. | au87101a ufdisk
