Part 4: Advanced – Extracting from Linux Firmware

If no Windows driver is found, consider that Linux supports Alcor FA04 with the generic usb-storage or ccid driver. You can extract the firmware from a Linux installation:

  1. Boot a Linux live USB (e.g., Ubuntu).
  2. Run lsusb – note the bus and device ID of the FA04.
  3. Dump the firmware: sudo cat /sys/bus/usb/devices/X-Y/firmware > alcor_fa04.bin
  4. Back in Windows, use a tool like Alcor Firmware Loader (available from FlashBoot.ru) to load this binary into the device's temporary memory.

Warning: This is for advanced users only. Incorrect firmware can brick the device.

Conclusion: No Longer Unknown

The string "alcor micro unknown fa00 f w fa04 work" represents a classic Windows driver odyssey. But by decoding the hardware ID, sourcing OEM-specific packages, and understanding mode-switching behavior, you can transform that yellow exclamation mark into a functioning device.

Remember: Always back up your current driver state before forcing INF installations. Use System Restore or DriverBackup. And when in doubt, the Linux kernel (drivers/usb/storage/alauda.c or drivers/ccid/ccid_usb.c) holds the canonical implementation – use it to reverse-engineer the correct Windows INF.

Now go ahead – make that FA04 work.

The identifier Unknown FA00 f/w FA04 typically appears in AlcorMP mass production tools when a USB flash drive's controller is corrupted or incorrectly identified. This specific error often maps to the Alcor AU6989SN-TA or AU6989SNCS-TA controller series. Core Technical Profile

Controller Identity: The "FA00" code is not a standard model name but an internal designation often associated with the AU6989SN-TA . alcor micro unknown fa00 f w fa04 work

Common Symptoms: The drive may show as "No Media," display 0 bytes of capacity, or fail to show a Flash ID (FID).

Flash ID Error: A common red flag is a fake or missing FID (e.g., 898989898989), which suggests a communication failure between the controller and the NAND memory chip. Recovery and Repair Procedures

To resolve the "Unknown FA00" status, you must force the controller into a state where it can be reflashed using a compatible Alcor Micro Mass Production Tool (AlcorMP).

Identify Exact Hardware: Use tools like ChipGenius or Flash Drive Information Extractor to confirm the VID (Vendor ID) and PID (Product ID). Standard Alcor values are often VID: 058F and PID: 1234. Enter Test Mode (Hardware Reset):

If the software does not detect the drive, you may need to manually short the pins on the NAND flash chip (typically pins 29-30 or 30-31) while plugging it into the USB port to force "Test Mode". Software Configuration: Run AlcorMP.exe as an administrator.

Navigate to the Setup or Driver button and enter your specific VID/PID.

Select High Level Format for a quick fix, or Low Level Format if the NAND has bad blocks. Flashing the Firmware: Ensure the tool version supports the series.

Press Start to begin the mass production process, which will rewrite the controller's firmware (FA04) and re-partition the drive. Technical Challenges

BGA vs. TSOP48: Many modern Alcor-based drives use BGA memory chips, which makes manual pin-shorting difficult compared to older TSOP48 chips.

Firmware Mismatch: Using the wrong version of AlcorMP can result in "Load Firmware Error" or permanent bricking of the controller. AI responses may include mistakes. Learn more Alcor [Fa00] Aka Au6989sn-Ta - Usb Flash Drive - Scribd
