Fa00 F W Fa04 Fixed: Alcor Micro Unknown

The phrase "Unknown FA00" is a common sight in flash diagnostic tools like ChipGenius or Flash Drive Information Extractor. It usually indicates that the controller firmware is either corrupted, generic, or unrecognized by older software databases.

The transition to FA04 (Fixed) implies a successful intervention:

This is the most reliable solution and likely what is referred to in your search string.

The string “alcor micro unknown fa00 f w fa04 fixed” is a status message from a flash drive repair tool. It indicates the drive is in an unrecognized state (FA00), but the user/technician applied a forced fixed-disk configuration using firmware profile FA04. Without the correct MP tool and flash database, the drive will not function normally.

Recommendation: Obtain the exact AlcorMP version matching your drive’s controller (e.g., AU6989SN) and repeat the process with “Auto Detect Flash” disabled, manually selecting a FA04 entry if available.

If you have additional context (e.g., tool name, error log, or drive model), I can refine the analysis further.

Getting the "Unknown [FA00]" error on an Alcor Micro USB controller typically indicates a firmware mismatch or a controller that has entered a "read-only" or "no media" state due to corrupted instruction sets. This specific code, often associated with the AU6989SN-TA or AU6989SNCS-TA controller, means the mass production tool (MPTool) sees the hardware but cannot identify the specific firmware profile needed to initialize it. Why "Unknown [FA00]" Happens

The error usually appears when using diagnostic tools like ChipGenius or Flash Drive Information Extractor. It occurs because:

Version Incompatibility: The version of AlcorMP you are using doesn't have the configuration files for that specific controller revision.

Firmware Corruption: The existing firmware (F/W) on the chip is damaged, leading it to report a generic or "unknown" ID like FA00 instead of its true model number.

Write Protection: The controller may lock itself into a "fixed" read-only state to prevent further data loss if it detects NAND flash errors. Step-by-Step Fix for Alcor Micro [FA00]

To resolve this, you must "re-flash" the controller using the correct AlcorMP or FC MPTool. 1. Identify the Exact Hardware

Before downloading software, confirm your VID and PID. For Alcor Micro, these are typically 058F and 6387 or 1234. Use ChipGenius to find the Flash ID (FID) code (e.g., 453E9803). This code is critical for picking the right tool version. 2. Find the Right Tool Version

The "FA00" error is picky. If one version of AlcorMP fails with an "Unknown Flash" error (Error 30400), you must try a different release.

Search for versions tagged specifically for AU6989SN on repositories like USBDev.ru or FlashDrive-Repair.

Commonly successful versions for this error include AlcorMP_UFD 13.xx.xx or AlcorMP v15.09.15.00. 3. Configure the MPTool Run as Administrator: Open AlcorMP.exe.

Load the Driver: Click the Driver button, enter your VID/PID (e.g., 058F 1234), and click Install. Setup/Configuration: Go to Setup (password is usually blank or "888888").

On the Flash Type tab, if your drive is a "fake" or low-quality generic, set Optimize to "Capacity Optimize" and Scan Level to "FullScan4".

On the Mode tab, ensure "Pure Disk" is selected unless you specifically want a "Fixed Disk" partition.

Start the Process: Click Start (A). The tool will format the NAND and write new firmware. This may take 5–30 minutes depending on the "Scan Level" chosen. 4. Post-Fix Verification

Once the status bar turns green, unplug the drive and plug it back in. If the drive shows the correct capacity but remains "Fixed" (Local Disk) instead of "Removable," you can toggle this setting in the Mode tab of the AlcorMP settings before running the flash again. Troubleshooting "Invalid Device"

If you get Error 20000 (Invalid device), it means the software version is too old for your hardware. You must find a newer version of the AlcorMP suite that specifically supports the F/W FA04 or FA00 instruction set. Alcor Micro - USBDev.ru

**Cons:

The Alcor Micro "Unknown [FA00]" error indicates a communication failure between the controller and the flash memory chip.

The error signature Unknown [FA00] F/W FA04 is a classic symptom of a corrupted, unsupported, or physically damaged USB flash drive utilizing an Alcor Micro controller (such as the AU6989SN-TA series). 🔍 Technical Analysis of the Error

Unknown [FA00]: This is not a real Alcor controller model. The AlcorMP mass production tool returns FA00 as a generic fallback code when it cannot communicate with the NAND flash memory to read its unique Flash ID (FID).

F/W FA04: This denotes the specific firmware version the tool is attempting or failing to read/write during the detection process.

No FID (Flash ID): When this error occurs, the software usually reports an FID of 00 00 00 00 00 00 or fails to read it entirely. Without an FID, the mass production tool does not know what type of memory is on the board and cannot reflash it. 🛠️ Root Causes & Fixed Solutions

The table below outlines why this happens and how specialized technicians and forum communities (like the Alcor Micro section on USBDev) address it. Technical Explanation Resolution / "Fix" Physical/Soldering Failure

A severed data line or fractured solder ball on the NAND chip prevents the controller from reading the FID. Requires hardware reflow or resoldering of the chip pins. Controller Logic Freeze

The controller is stuck in a loop reading corrupt data and ignores external software commands.

Put the flash drive into Hardware Test Mode by shorting specific pins on the NAND chip. Incompatible Software

The version of AlcorMP being used does not possess the parameters for your specific NAND memory.

Download a community-modified version of the software, such as the editions by NAT27. ⚡ Step-by-Step Recovery Procedure

To fix this specific error, users typically follow standard mass production recovery procedures. Note that this process will completely wipe all data on the drive. 1. Identify the Physical Controller

Do not rely on software readouts since they are giving false FA00 data. Crack open the plastic casing of the USB drive.

Read the physical laser-etched model number on the small square chip (e.g., AU6989SN-TA, AU6989AN). 2. Force Hardware Test Mode

If the drive still shows FA00 or no FID, you must force the controller to ignore its corrupted firmware: Locate the large rectangular NAND flash chip.

Use a needle or precision tweezers to short circuit two data pins (usually pins 29-30 or 43-44 on a standard TSOP chip) right as you plug it into the computer.

Once the software detects the drive with a proper generic status (and hopefully reads a real FID), remove the short. 3. Use the Correct Mass Production Tool

Visit a database of production tools like the Alcor Micro Downloads on USBDev.

Download a modified version of AlcorMP or FC MpTool that matches your physical controller.

Open the program, insert the flash drive, click Setup, configure it to your flash type, and hit Start to overwrite the corrupted firmware. Alcor Micro - USBDev.ru
