The "Alcor Micro Unknown FA00 F/W FA04" error typically indicates that your USB flash drive's controller (often the AU6989SN-TA
or similar) is not being correctly identified by standard operating systems or generic repair tools. This can happen due to firmware corruption or physical memory chip failure. 1. Identify Your Chip Details
Before attempting a fix, you must confirm the exact hardware specs.
Download ChipGenius: Use this tool to find the exact VID (Vendor ID), PID (Product ID), and Controller Model
Verify the Controller: While the error shows "FA00," this is often an alias for the Alcor AU6989SN-TA or AU6989SN-GT chips. 2. Use the Alcor Mass Production (MP) Tool
The primary way to fix firmware issues is through a dedicated "Mass Production" tool designed for Alcor chips.
Download the Correct Tool: Look for AlcorMP versions specifically compatible with the AU6989 series (e.g., AlcorMP AU698x Configure Driver Settings: Open AlcorMP and click the Driver button. Enter your device's VID and PID (e.g., 058F and 1234). Click Add VID/PID, then Save InstallDrive.
Connect in Test Mode: If the drive is still not detected, you may need to manually switch it to Test Mode by shorting specific pins on the controller chip while plugging it in (advanced users only). Flash the Firmware: Press Refresh until the tool detects your drive.
In Setup, ensure Factory Mode and Auto Disc Size are selected.
Click Start to begin the low-level format and firmware re-write. Note: This will erase all data. 3. Alternative Recovery Options If the MP Tool fails, try these standard Windows utilities:
Diskpart Clean: Open Command Prompt as admin, type diskpart, then list disk. Identify your USB number and type select disk X (replace X with your number), then clean and create part pri to reset the partition table.
Check for Physical Errors: If the tool reports "No FID" or "898989898989," it often indicates a permanent hardware failure of the flash memory chip rather than a software error.
The phrase "Alcor Micro Unknown FA00 F/W FA04" refers to a specific error state in Alcor Micro USB controller chips (typically the AU6989 series), where the device is not recognized properly by the operating system or flash repair tools. This often occurs when the flash drive's firmware is corrupted, leading to "No Media" or "0 Byte" errors. Understanding the Error
FA00: This is a common error code reported by Alcor recovery software (like AlcorMP) indicating that the controller chip is detected but the flash memory (FID) is unknown or not responding correctly.
F/W FA04: Refers to a specific firmware version or state that the recovery tool expects or has identified during a failed operation. How to Fix "Unknown FA00"
To resolve this, you typically need to use a Mass Production (MP) Tool to reflash the controller's firmware.
Identify the Chip: Use a tool like ChipGenius to find the exact Controller Part Number (e.g., AU6989SN) and the Flash ID (FID).
Download the Matching Tool: Search for an AlcorMP or Alcor recovery tool version specifically compatible with your controller and Flash ID. Reliable sources for these tools include community sites like USBDev.ru.
Use "Test Mode" (If Not Detected): If the tool does not see the drive, you may need to manually short two pins on the controller chip while plugging it in to force it into "test mode," allowing the software to recognize it. Configure VID/PID: In the AlcorMP settings: Click Driver. Add your device's VID/PID (often 058F/6387 or 058F/1234). Save and refresh the tool.
Start Repair: Once the drive appears (often showing a "CAP" or capacity error), press Start to begin low-level formatting and firmware restoration.
Note: Reflashing firmware is a "destructive" process that will permanently erase all data currently on the USB drive.

When your Alcor Micro flash drive displays "Unknown [FA00]" with firmware (F/W) "FA04," it indicates that the Alcor Mass Production (MP) tool recognizes the controller but cannot identify the specific flash memory chip (FID) or its configuration. This usually results in a "No Media" or "0 Byte" error. The Meaning of the Error
[FA00]: This is a placeholder code often associated with the AU6989SN-TA or AU6989SNCS-TA controller series.
Unknown F/W FA04: This means the current firmware version is unsupported or corrupted, and the utility lacks the necessary binary (.BIN) files for that specific controller-flash combination.
Root Cause: Either the flash chip is physically damaged, the controller is in a "hung" state, or the MP tool version is too old to support the newer flash memory used in your drive. How to Fix the [FA00] Error
Switch to Test-Mode (Manual Reset)If the software cannot "see" the flash chip, you may need to force the controller into test-mode. Carefully open the drive's casing.
Locate the flash memory chip and use a needle or tweezers to briefly short the data bus pins (typically pins 29-30 or 30-31) while plugging the drive into the USB port. Once detected as a "generic" device, release the short.
Use the Correct AlcorMP VersionStandard versions often fail on [FA00] chips. Look for "Modified" editions by NAT27 on USBDev.ru which have expanded flash lists. Download several versions of AlcorMP or FC MPTool.
Ensure you run the utility before plugging in the flash drive. Configure Driver & VID/PID Open AlcorMP and click the Driver button. Enter the default Alcor VID: 058F and PID: 6387 (or 1234). Click Add VID/PID, then Save InstallDrive. Press Refresh(R) to see if the drive appears.

The glowing green light on the flash drive was mocking him. Leo starred at his monitor, where Device Manager displayed a dreaded yellow triangle. The label read: Alcor Micro USB 2.0 Card Reader - Unknown Device (Error Code: FA00).
All of his client's wedding photos were trapped on that SD card. 🔍 The Rabbit Hole
Leo was a freelance photographer, and this was his worst nightmare. He had inserted the card, heard the chime, and then... nothing.
He had spent the last four hours scouring the deepest, darkest corners of the internet. He tried rebooting his PC. He tried three different USB ports. He tried updating the drivers automatically.
Every attempt was met with that stubborn, cryptic error: FA00. 💡 The Breakthrough
It was 3:00 AM. Leo's eyes were bloodshot. He found himself on an archived Russian tech forum, translating pages of text via his browser.
A user named SiliconSage had posted a thread five years prior.
"Alcor Micro chips throw FA00 when the internal firmware loses its pointer. It is not dead. It is just confused."
Leo held his breath. SiliconSage had attached a custom, modified firmware utility labeled "ALCOR_FA04_FIX.exe". 🛠️ The Operation
Leo downloaded the sketchy-looking zip file. His antivirus immediately flagged it. He took a deep breath and overrode the warning. Desperate times called for desperate measures.
He opened the tool. The interface looked like it was designed for Windows 98. He selected the bricked drive from the dropdown menu. He loaded the custom FA04 firmware payload. He clicked the button labeled simply: FLASH.
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
