: Change this setting from High Level Format to Low Level Format / Full Scan4 . This step forces the utility to systematically map out broken NAND blocks.
Toggle the dropdown option and set it to Capacity Optimize . This commands the system to map around failing hardware blocks rather than aborting.
The "FA00" code is not a standard model name but an internal designation often associated with the AU6989SN-TA .
Before downloading any software, you need to know the exact hardware inside your USB.
In some embedded Linux or custom firmware logs:
Navigate to the or Driver button and enter your specific VID/PID.
This is the most promising approach for logical corruption. Mass Production (MP) tools are factory-level utilities designed to flash the controller's firmware.
Alcor Micro makes controllers for USB flash drives, SD card readers, and hubs. If you see this in with a yellow exclamation or in chip testing tools like ChipGenius , it often means:
To resolve this, you must "force" the drive into a mode where it can be reflashed with the correct firmware. Repair of damaged flash drives - elektroda.com
For instance, the is a single-chip USB hub controller supporting four downstream ports, allowing a single USB connection to branch out to a mouse, keyboard, scanner, or printer. The AU6254 is a USB 2.0 hub controller built with a Transaction Translator (TT), which helps optimize performance when devices of different speeds are connected to the same hub.
), the drive likely has a terminal hardware failure or is a low-quality counterfeit that cannot be permanently fixed. Do you have the ChipGenius
Technically, a controller with the model number "FA00" does not exist; this code is often a firmware-level error message or a placeholder used when the mass production tool (MPTool) cannot correctly identify the specific chip model. Recovery and Repair Steps
In the realm of USB flash drive repair and data recovery, encountering an "Unknown" device with a Vendor ID (VID) of and a Product ID (PID) of FA00 (or sometimes FA04) is a very common occurrence. This state indicates that the flash drive's controller has entered "Factory Mode" or "Safe Mode."
The Alcor Micro FA00 / FA04 error is a classic example of a simple hardware component getting lost in the shuffle of modern operating systems. It is rarely a hardware failure; it is simply a communication breakdown between your SD card slot and Windows.
