Troubleshooting Alcor Micro "Unknown [FA00]" Firmware Errors

The Alcor Micro Unknown [FA00] error typically appears when a flash drive's controller is bricked, or the production software cannot identify the firmware (often showing as F/W FA04 or FA05). This usually indicates a firmware mismatch or a fake drive where the reported capacity doesn't match the hardware. Why the FA00 Error Occurs

Controller Mismatch: The production tool (AlcorMP) is looking for a specific controller ID (like AU6989SN), but the chip returns a generic or corrupted "FA00" code.

Hardware Failure: Physical damage to the USB port or the flash chip itself can prevent the controller from sending a proper "Device Descriptor".

Fake Flash: Inexpensive drives often use modified firmware to report fake sizes. When these fail, they revert to a raw "Unknown" state. How to Fix the "Unknown FA00" Issue

To resolve this, you must "force" the drive into a mode where it can be reflashed with the correct firmware. Repair of damaged flash drives - elektroda.com

The error "Alcor Micro Unknown [FA00] - F/W FA04" indicates a firmware or controller issue on a USB flash drive, typically identifying it as an AU6989SN-TA or AU6989SNCS-TA controller. This error usually occurs when the drive's firmware is corrupted, leading it to report generic identifiers like VID 058F and PID 1234 instead of its actual specifications. Troubleshooting Steps

To resolve this using AlcorMP (Mass Production Tool), follow these specific actions: Configure Driver Settings: Open AlcorMP and locate the Driver button.

Manually enter the VID/PID as 058F and 1234 (or the specific IDs shown by your device). Click Add VID/PID, then select Save InstallDrive. Detection & Test-Mode: Plug the USB drive into your computer.

If the drive is not detected, you may need to manually switch it into "test-mode" (this often involves shorting specific pins on the controller chip, though this is risky and usually a last resort). Click Refresh (R) in AlcorMP if it still doesn't appear. Firmware Repair:

Once detected, use AlcorMP to perform a High Level Format or Low Level Format.

Note: Low-level formatting may significantly reduce reported capacity if the tool detects bad sectors. Common Causes

Firmware Mismatch: The controller "FA00" is often a placeholder for unknown or generic Alcor controllers.

Hardware Failure: If AlcorMP cannot identify the Flash ID (FID), the drive may have a mechanical or electrical failure that software cannot fix. alcor micro unknown fa00 f w fa04 work

Counterfeit Hardware: Some drives reporting these generic IDs are "no-name" or fake capacity drives that use Alcor controllers to spoof storage limits.

For standard drive errors without firmware corruption, tools like DiskGenius can be used to check for bad sectors or rebuild partitions.

To get your Alcor Micro unknown FA00 F/W FA04 device to work, you generally need to address a firmware identification error or a driver conflict. This specific combination of identifiers (FA00 controller with FA04 firmware) often appears when a USB flash drive or card reader is in a "stalled" state, showing 0 bytes or "No Media" in Windows. Understanding the Error

The "FA00" identifier is often a generic placeholder for Alcor controllers like the AU6989SN-TA or AU6989SNCS-TA

when the system cannot properly read the Flash ID (FID). "FA04" typically refers to the specific firmware version loaded onto that controller. When these appear together as an "unknown device," it usually means the hardware is functional, but the software communication has broken down. Step-by-Step Fixes to Get It Working 1. Reinstall the Driver via Device Manager

Before attempting complex firmware flashes, try a clean driver reset: Open Device Manager (Win + X). Expand Universal Serial Bus controllers or Memory technology devices. Right-click the Alcorlink USB 2.0 Card Reader or the "Unknown Device" and select Uninstall device.

Check the box to Delete the driver software for this device if available.

Restart your computer. Windows will attempt to reinstall a fresh generic driver upon reboot. 2. Use Manufacturer-Specific Drivers

Generic Windows updates can sometimes cause Alcor devices to stall. If you are on a laptop, download the official OEM driver:

HP Users: Visit the HP Software and Driver Downloads page. Search for "Alcorlink Card Reader" under the Storage or Chipset category for your specific model.

Dell Users: Use the Dell Support site to identify your system and download the "Memory Card Reader" driver under the Chipset section. 3. Firmware Restoration (For USB Flash Drives)

If the device is a flash drive showing 0 bytes, you may need a Mass Production (MP) tool to "re-stitch" the firmware: Identify the exact controller using a tool like ChipGenius. Download the corresponding version of AlcorMP (e.g., AlcorMP 16.11.01.MD Scenario 1: USB Drive or Card Reader Not

In the tool settings, try setting Scan Mode to "Low Level Format" and MP Mode to "Capacity Optimize". Warning: This process will erase all data on the device. 4. Disable USB Selective Suspend

Power management settings can sometimes prevent Alcor readers from "waking up" properly: Go to Control Panel > Power Options > Change plan settings. Click Change advanced power settings.

Expand USB settings > USB selective suspend setting and set it to Disabled. Quick Troubleshooting Checklist Potential Solution 0 MB / No Media Use AlcorMP tool to reflash firmware. Yellow Warning ! Uninstall driver and restart. Not Detected Try a different USB port (preferably USB 2.0). Code 47 Physically unplug the device and plug it back in.

The identifier Unknown [FA00] — F/W FA04 (or similar variations like FA02) typically indicates that a USB flash drive with an Alcor Micro

controller is in a corrupted state or has been identified as a "fake" drive.

Technically, a controller with the model number "FA00" does not exist; this code is often a firmware-level error message or a placeholder used when the mass production tool (MPTool) cannot correctly identify the specific chip model. Recovery and Repair Steps

To fix a drive displaying this "Unknown [FA00]" status, you can attempt the following recovery procedures using specialized tools: Identify the Real Controller : Use a tool like ChipGenius

to get the actual hardware details (VID, PID, and Flash ID) since the software report "FA00" is unreliable. Use AlcorMP (Mass Production Tool)

: Download the version specific to your controller series (often the AU6989SN-GT/TA series) from specialized repositories like FlashBoot.ru Configure Manual Detection AlcorMP.exe (Run as Administrator). or click the Manually enter your device's Save the settings and reconnect the drive. Deep Scan Settings

: If the drive is detected but fails to format, change the scan level in settings to Full Scan4 and set the mode to Capacity Optimize to force a thorough repair of corrupted memory cells. Test-Mode (Hardware Fix)

: If software detection fails entirely, you may need to manually enter "Test-Mode" by short-circuiting specific pins on the flash memory chip (NAND) before plugging it in, which forces the controller to be recognized by the Windows OS. : These procedures will wipe all data

on the drive. If the Flash ID (FID) appears as a repeated sequence (like 898989898989 FA00 = Unknown flash type or bad NAND ID F

), the drive likely has a terminal hardware failure or is a low-quality counterfeit that cannot be permanently fixed. Do you have the ChipGenius

Solving the Enigma: How to Make "Alcor Micro Unknown FA00 F W FA04 Work" in Windows
Why is it Showing as Unknown?
The main reason this happens is the evolution of Windows Update.

Legacy Hardware: Many of these card readers are slightly older hardware revisions. While Windows 10 and 11 are excellent at finding drivers automatically, they sometimes miss specific proprietary controllers like the Alcor FA00 series if the generic Microsoft driver database doesn't match the specific Hardware ID (PID_0039).
Generic Drivers: Windows might try to install a generic USB driver, but it fails to initialize the specific read/write protocols of the Alcor chip, leaving the device "bricked" in Device Manager.

Step 2: Check for Microsoft Native Drivers (Windows 10/11)
If you are on Windows 10 or 11, try forcing Microsoft’s generic driver.

Right-click the unknown device → Update driver → Browse my computer → Let me pick from a list.
Select Smart card readers or Universal Serial Bus devices.
Choose Microsoft Usbccid Smartcard Reader (WUDF).
Click Next. If it works, your device follows CCID standards. Many FA04 devices do not.
