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.
Low-Level Format SettingsIf the device is detected but fails to flash: Go to Setup (S) (password is usually blank or "888888").
In the Flash Type tab, ensure the flash chip is correctly identified. If it still says "Unknown," the tool is incompatible. In the Other tab, set the "Current" to 200MA. It looks like a short descriptor of a device/firmware entry

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. If you want help troubleshooting or decoding this (e
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.
We will approach this in two phases: Phase A attempts to recover the drive without losing data. Phase B is a destructive repair (you lose data, but get a working drive).
