The identifier "Unknown FA00" with firmware (F/W) version 3613 refers to a specific state encountered when using recovery tools for USB flash drives powered by Alcor Micro controllers (such as the AU698x series). This usually happens when the software (AlcorMP) cannot fully identify the flash memory chip or the controller’s current state is corrupted. Best Tools for Recovery
To fix a drive showing "Unknown FA00" or "F/W 3613" errors, you must use a production utility (MPTool) that is compatible with your specific controller-memory combination.
AlcorMP (Standard Version): This is the primary utility for flashing Alcor USB 2.0 chips. You can find the latest versions, such as ALCOR U2 MP v23.08.07.00.H, on specialized sites like USBDev.ru.
AlcorMP MD (Modified Editions by nat27): These are often better for "unknown" errors because they include updated flash lists and additional driver support to force identification of generic or fake chips.
FCMPTool: Originally for counterfeit or "fake" drives, this tool is now largely integrated into modern AlcorMP versions but remains useful for drives that the standard tool refuses to recognize. Steps to Resolve "Unknown FA00 / F/W 3613"
Identify the Chip: Use a hardware info tool like ChipGenius or Flash Drive Information Extractor to find the exact Controller Model (e.g., AU6989SN) and Flash ID (FID).
Download Compatible Software: Locate a version of AlcorMP that explicitly lists your controller and memory type (e.g., MLC-8K, eD3, or TLC) in its description. Adjust Scan Settings:
If the drive is still "Unknown," go to the Setup menu (usually no password or "0000"). Change Scan Level to "Full Scan" or "High-level Format".
Set MP Mode to "Capacity Optimize" for the best chance of recovery.
Manual Driver Installation: If the tool does not see the drive, use the LoadDriver.exe utility (often found in the tool's folder) to manually install the Alcor bus driver for your specific VID/PID. Common Causes
Bad Sectors: If the tool shows "Bad Block" errors, the memory chip may be physically failing.
Wrong Software Edition: Alcor tools are highly specific. A version meant for eD3 memory will likely fail on TLC memory.
Write Protection: This "Unknown" state often triggers a write-protection error, which only a low-level format via these tools can clear.

The identifier Alcor Micro Unknown [FA00] F/W 3613 typically refers to a specific state of a USB flash drive controller, often encountered during firmware recovery or when a drive has become "bricked." The
code is not a standard controller model but rather a status indicator (often signifying "Fixed Address" or a specific boot mode) used by mass production tools. Key Technical Aspects Controller Identity
: While listed as "Unknown," this firmware signature is most commonly associated with Alcor Micro AU6989 series chips, specifically variants like the AU6989SN-GT/GTA Flash ID (FID)
: In a healthy state, the drive should return a 6-byte Flash ID (e.g., AD DE 94 EB 74 44 ). If the tool shows 89 89 89 89 89 89
or similar repeating patterns, it usually indicates a hardware failure or a "fake" drive that has lost its mapping. Firmware (F/W 3613)
: This specific version identifies the microcode required to manage the NAND flash. When a drive shows "Unknown [FA00]," it means the software cannot automatically match the firmware to the physical memory chip. Recovery Potential To restore a drive showing this status, users typically use AlcorMP (Alcor Micro Production Tool) . For firmware , the following steps are generally used by technicians: Chip Selection
