This error typically occurs when an Alcor Micro USB controller (common in flash drives and card readers) has corrupted firmware or is a generic/fake drive that the computer cannot identify. Understanding the Error
Unknown [FA00]: This is a generic status code returned by the controller when it fails to identify its model or flash memory chip (FID).
F/W FA04: This refers to the specific firmware version (or failure state) currently reported by the device.
Symptoms: The drive may show up as "No Media," "0-byte capacity," or "Disk is Write Protected". Potential Fixes
To recover the drive, you generally need a "Mass Production Tool" (MPTool) compatible with your specific hardware.
Identify the Real Chipset: Use a tool like ChipGenius or Flash Drive Information Extractor to find the actual Controller Part-Number and Flash ID (FID). Download the Correct Utility:
Visit specialized databases like USBDev.ru to find the version of AlcorMP that supports your specific FID.
For Transcend-branded drives, use the Transcend Online Recovery Tool which often resolves these "FA00" errors automatically. Run AlcorMP: Open the tool before plugging in the drive.
If the drive is not detected, use the "Driver" button in the tool to manually add your device’s VID/PID (Vendor and Product ID).
Perform a "High Level Format" or "Full Scan" to re-flash the firmware.
Warning: Re-flashing firmware will permanently erase all data on the drive. If the FID shows a nonsensical value like 898989898989, the hardware likely has a physical electrical failure and cannot be fixed.

The designation Alcor Micro Unknown [FA00] with firmware FA04 typically refers to a specific state of a USB flash drive controller, often identified by diagnostic tools like ChipGenius when the device is corrupted or running a generic firmware revision. Technical Identification The FA00 tag is frequently an alias for the Alcor AU6989SN-TA or AU6989SNCS-TA
controller series. When a drive displays as "Unknown [FA00]," it often indicates that the standard Mass Production (MP) tool cannot fully communicate with the NAND flash memory chip, sometimes resulting in a "No FID" (Flash ID) error. This can happen if: The drive has suffered electrical or mechanical failure.
The controller is a newer or "fake" variant not yet documented in older diagnostic databases.
The firmware (e.g., FA04 or FA00) is a factory-level revision intended for mass production rather than end-user updates. Troubleshooting and Recovery
If your device is showing 0MB capacity or "No Media," you can attempt recovery using specialized Alcor tools:
Identify the Chip: Use ChipGenius to find the exact VID (usually 058F) and PID (often 1234 or 6387).
Mass Production Tools: Download the specific version of AlcorMP or ALCOR U2 MP
that supports the AU6989 series from repositories like FlashBoot.ru or USBDev.ru.
Driver Installation: Some tools require you to manually add your VID/PID into the tool's InstallDrive configuration to force detection.
Low-Level Format: Using these tools to "re-burn" the firmware can sometimes restore functionality, though it will erase all data. The "Fake Drive" Context
In many community reports, the "Unknown [FA00]" identifier appears on high-capacity advertised drives (e.g., 512GB) that actually contain much smaller, poor-quality NAND chips (e.g., 16GB). Testing such drives with H2testw often reveals massive sector errors, indicating the firmware was spoofed to report false capacity.
Are you trying to recover data from this drive, or are you looking to reflash the firmware to make the device usable again? Alcor Recovery tool for repairing Alcor chip controllers
If you have encountered an "Alcor Micro Unknown Device" in your Device Manager, often accompanied by the firmware (F/W) codes FA00 or FA04, you are likely dealing with a controller-level error in a USB flash drive or a smart card reader. This specific error typically indicates that the device's firmware has become corrupted or is in a "factory" state where the operating system cannot recognize its basic parameters. Identifying the Problem: FA00 and FA04
In the world of Alcor Micro controllers, firmware codes like FA00 or FD00 are internal identifiers that appear when the device is stuck in a bootloop or low-level communication mode.
FA00: Often seen when the controller is functional but cannot communicate with the flash memory chip.
FA04: Generally indicates a specific firmware version mismatch or a hardware-level read failure during the initialization process. How to Fix Alcor Micro "Unknown Device" Errors 1. Locate the Correct Production Tool (AlcorMP)
Standard Windows drivers will not fix a firmware-level "Unknown Device" error. You must use a "production tool" specifically designed for Alcor chips.
AlcorMP (Alcor Micro Production Tool): This is the primary utility for re-flashing and repairing Alcor-based drives.
Find your Chip ID: Use a tool like Flash Drive Information Extractor or ChipGenius to find your specific VID (Vendor ID) and PID (Product ID). Common Alcor VIDs include 058F. 2. Using AlcorMP for Repair | Item | Verdict |

An essay regarding "Alcor Micro Unknown FA00 F/W FA04" explores the intersection of hardware identification, firmware failure, and the limitations of modern plug-and-play operating systems. This specific error string typically appears in device diagnostic tools like ChipGenius
when a USB flash drive or card reader equipped with an Alcor Micro controller suffers from a firmware corruption or a "No FID" (Flash ID) error. Understanding the Component
The core of this issue lies with the controller, often identified as the Alcor AU6989SN-TA
or similar variants. In a healthy state, these controllers manage the data flow between a computer and NAND flash memory. However, when the controller returns a status of "Unknown FA00" or "F/W FA04," it signifies that the device is in a bootloader or "test mode," unable to communicate with the internal flash memory chip. This is frequently accompanied by a "0 Byte" or "No Media" status in Windows Disk Management. Causes of "Unknown" Identification
The "Unknown" status and the specific "FA00" firmware string are symptomatic of several failures: Firmware Corruption
: The low-level instructions (firmware) that tell the controller how to read the flash chip have been damaged. Hardware Malfunction
: A physical break in the circuit, such as a cold solder joint on a BGA (Ball Grid Array) flash chip, prevents the controller from detecting the memory's Flash ID (FID). Driver Mismatches
: On the software side, the Windows operating system may fail to identify the device, labeling it an "Unknown USB Device (Device Descriptor Request Failed)" Recovery and Maintenance
Fixing these devices usually moves beyond standard Windows troubleshooting. While basic steps like uninstalling the device in [Device Manager](microsoft.com or disabling "EnhancedPowerManagementEnabled"
in the Windows Registry can resolve software-level glitches, true firmware issues require specialized mass-production tools. Utilities such as allow users to manually input the Vendor ID (VID) Product ID (PID) —typically
for Alcor devices—to attempt a low-level format and firmware re-flash. For integrated hardware like card readers found in laptops, manufacturers like offer dedicated Alcor Micro USB Smart Card Reader Drivers
to ensure the operating system can correctly translate these specific hardware strings into functional services.
In conclusion, the "Alcor Micro Unknown FA00 F/W FA04" error is a technical signal that a device is functionally "brain-dead" but electrically present. Resolving it demands a precise combination of official manufacturer drivers for system integration or specialized firmware recovery tools for portable storage. specific download link
