Based on user reports across tech forums (Reddit r/techsupport, Tom’s Hardware, and Microsoft Answers), the FA00 error appears in these specific devices:
The FA00 chip is often a masked variant of the AU6370 or AU6371 series. You can try the driver for those:
This "Unknown [FA00]" designation typically appears when ChipGenius
or similar USB diagnostic tools fail to find a matching entry in their local database for an Alcor Micro controller.
Based on community research and technical teardowns, here is a write-up on what this device likely is and how to handle it. Identity: The Alcor Micro "FA00" is a specific identifier (often paired with firmware like ) that generally points to the Alcor AU6989SN-TA AU6989SNCS-TA ) controller. Common Use Case:
These controllers are standard in low-cost or "generic" USB 2.0 flash drives, often found in 1GB to 32GB capacities. Controller Vendor: Alcor Micro Corp. (VID = 058F, PID = 1234). Flash Type: It is frequently paired with QLC/TLC NAND flash. Why it shows as "Unknown" Database Gap:
Diagnostic tools use internal lists to name chips. When the controller reports "FA00," and it isn't explicitly mapped to "AU6989SN," the tool defaults to "Unknown". Counterfeit Risk: In some cases, drives showing "FA00" alongside an invalid Flash ID (FID)
like "898989898989" are indicative of fake or damaged hardware. Repair and "Mass Production" (MP) Tools
If the drive is "Write Protected" or showing 0MB capacity, you must use an
tool. Because "FA00" is a variant of the AU6989SN series, you should look for tools specifically supporting the AU6989SN-TA Basic Recovery Steps: AlcorMP (Mass Production Tool) for the AU6989SN-TA. Configuration: AlcorMP.exe and enter the VID/PID (usually Add VID/PID Save InstallDrive Plug in the drive. If detected, hit
to re-flash the firmware. This will wipe all data but typically restores the drive's functionality.

If your computer reports this exact "Unknown [FA00]" status, it typically indicates that the drive’s firmware is corrupted, the controller is entering a "test mode," or you are dealing with a counterfeit device. What Does the Identifier Mean?
When a flash drive's internal software (firmware) crashes, it stops identifying itself correctly to Windows. Tools designed to read the hardware details will then report the following:
Controller Vendor: Alcor Micro (a common manufacturer of USB controllers).
Controller Part-Number: Unknown [FA00] — This means the diagnostic tool cannot find a matching chip in its database, or the chip is reporting a generic "fail" code.
F/W (Firmware): FA04 — This refers to the version of the low-level instructions currently active on the chip. Common Causes of the "FA00" Error
Firmware Corruption: The most frequent cause. A sudden power loss or improper ejection can "scramble" the firmware, making the drive appear as "No Media" or "Unknown Device".
Controller Malfunction: The Alcor AU6989SN-GT or similar series controllers sometimes default to this "FA00" state when they cannot communicate with the NAND memory chip.
Fake/Counterfeit Drives: Many "high capacity" cheap drives use Alcor controllers. If the fake capacity is exceeded, the controller may crash and report an unknown status.
Hardware Damage: If the physical connection between the controller and the memory chip is broken, the controller has nothing to report but a generic error. How to Fix Alcor Micro [FA00] Firmware Issues
Fixing this requires "re-flashing" the controller using Mass Production (MP) Tools.
Warning: Using these tools will permanently erase all data on the flash drive. 1. Identify the Real Chip Impact on Computing Experience While the exact function
Since the "FA00" code is generic, you need the Flash ID (FID) to find the right repair tool. Use ChipGenius to look for a string of letters and numbers like EC 3A 94 C3 A4 CA. 2. Download the Alcor MP Tool
Search for the specific version of the Alcor MP tool that supports your Flash ID. Reliable repositories for these specialized tools include: Alcor Micro - USBDev.ru
The identifier Alcor Micro [FA00] typically refers to the Alcor AU6989SN-TA
(or AU6989SNCS-TA) USB controller. This specific firmware string usually appears in diagnostic tools like ChipGenius or AlcorMP when a flash drive is corrupted, showing "No Media" or "0 Bytes". Understanding the Codes : This is the controller ID, often linked to the AU6989SN-TA : Refers to the current firmware version (FA04) flashed onto the controller. Unknown / No FID
: This status indicates that the mass production (MP) tool cannot identify the Flash ID (FID) of the memory chip, meaning the controller is working but cannot communicate with the NAND memory. Potential Fixes for Corrupted Alcor Drives
If your drive is showing these "Unknown" or "0 Byte" errors, you likely need a specific repair utility to re-flash the firmware: Identify the Exact Hardware : Use a tool like ChipGenius to confirm your VID (usually ) and PID (usually Download AlcorMP (Mass Production Tool) Search for a version compatible with the AU6989SN-TA controller. Reliable community repositories like host various versions of the Alcor Micro MP tools. Basic Troubleshooting Registry Edit : Clear write protection attributes via
or the Registry Editor if the drive is recognized but "Write Protected". Hardware Check
: If the MP tool still shows "No FID," the physical connection between the controller and the memory chip might be broken. Content Draft for Technical Support/Forums
If you are asking for help on a technical forum, use this format:
: Help Needed: Alcor Micro [FA00] Unknown Firmware FA04 - 0 Bytes Error Device Info Controller Alcor AU6989SN-TA (ID: FA00) : 058F / 1234 (or your specific codes)
: The drive is recognized by the system but shows "No Media" or "Unknown" in AlcorMP. Flash ID is not being detected.
Because "Alcor Micro unknown FA00 F W FA04 top" resembles a USB Device ID (VID/PID) or a firmware revision string, a traditional academic "paper" does not exist for this specific phrase. Instead, this is a technical identifier used in hardware diagnostics and driver development.
Below is a comprehensive technical white paper constructed to explain this specific hardware identifier, its function, and its relevance to computer hardware engineering.
The OS (Windows/Linux) issued a vendor-specific SCSI command or USB control transfer to the Alcor device. The device responded with a pattern the host driver did not recognize—either a malformed response or a debug stub left active in production firmware.
