The keyword "Alcor Micro USB Repair Tool AU6989SNGTC AU6998SN link" is so specific because generic versions fail.
The phrase "Alcor Micro USB Repair Tool AU6989SNGTC AU6998SN link" is your entry ticket, but success depends on understanding the controller's firmware zones. The AU6989SNGTC stores bad block tables in a volatile area. If power is lost during erase, the drive may permanently enter "Safe Mode" (2MB detected only).
Pro Tip: If after using the tool your drive shows only 4MB or 8MB capacity, you have successfully revived the controller but failed to map the NAND. Re-run the tool with "Erase All Blocks" (not just "Erase Bad Blocks").
