The Alcor Recovery Tool (often referred to as AlcorMP or Alcor Micro MP Tool) is a specialized low-level utility designed to repair, format, and restore USB flash drives that use Alcor Micro controllers. Unlike standard Windows formatting, these tools work at the firmware level to fix deep-seated errors. What is the Alcor Recovery Tool Used For?
This tool is primarily used to "unbrick" USB drives that exhibit the following symptoms:
Write Protection: The drive is "locked" and cannot be formatted or edited.
No Media / 0 Bytes: The computer recognizes the USB stick but shows it has no storage capacity.
Firmware Corruption: The drive is not recognized by the operating system due to software errors.
Fake Flash Removal: It can sometimes identify and fix drives that report a higher capacity than they actually have. How to Use the Tool
Using Alcor recovery tools requires caution because selecting the wrong firmware can permanently damage the hardware.
Identify Your Controller: Use a tool like ChipGenius to find your USB’s VID (Vendor ID), PID (Product ID), and Controller Part Number (e.g., AU6989SN).
Download the Matching Version: AlcorMP has many versions. You must download the one specifically matching your controller model (e.g., AlcorMP v16.02.19 for the AU6989SN-GT chip). Reliable repositories include USBdev.ru. Run the Utility: Open the .exe file (usually AlcorMP.exe).
Plug in your USB drive. If the drive is not detected, you may need to use "Test Mode" by shorting specific pins on the flash chip.
Click Start to begin the low-level format and firmware rewrite.
Finalize: Once the process finishes (often indicated by a green light or "OK" status), you may need to perform a standard Windows format to make the drive usable again. Important Warnings
Data Loss: Using these tools erases all data on the USB drive permanently.
Manufacturer Specific: This tool only works for drives with Alcor Micro chips. It will not work for Phison, Silicon Motion (SMI), or Sandisk controllers.
Risk of Bricking: If you use the incorrect version or the power is interrupted during flashing, the drive may become permanently unusable.

The Definitive Guide to the Alcor Recovery Tool: Revive Your "Dead" USB Drive
We’ve all been there: you plug in your USB flash drive, and instead of your files appearing, you’re greeted with a "Disk is Write Protected," "Please Insert Disk," or "Format Error" message. Before you toss that drive in the trash, there is a specialized solution that technicians have used for years: the Alcor Recovery Tool (often referred to as AlcorMP).
This article explores what the Alcor Recovery Tool is, how it works, and how you can use it to perform a low-level repair on your flash media. What is the Alcor Recovery Tool?
The Alcor Recovery Tool is a specialized "Mass Production" (MP) software designed specifically for USB flash drives that use Alcor Micro controllers.
Unlike standard Windows formatting tools that only touch the file system, AlcorMP interacts directly with the drive's firmware and controller chip. It is essentially the same software used in factories to initialize the drives before they are packaged and sold. Because it operates at such a deep level, it can often bypass "write protection" errors and logic failures that render a drive unusable to the average OS. When Should You Use It?
You should reach for this tool if your USB drive exhibits the following symptoms:
Write Protection Error: You cannot add or delete files, and Windows won't let you format it.
Zero Capacity: The drive shows up in Device Manager but reports 0MB of space.
Controller Errors: The drive is recognized as "Generic USB Hub" or "Unknown Device."
Firmware Corruption: The "brains" of the USB have glitched, and the hardware needs a factory reset. Step 1: Identify Your Controller (Crucial Step)
The Alcor Recovery Tool is not a universal fix. It only works if your USB drive contains an Alcor Micro chip (e.g., AU6981, AU6983, AU6989, etc.). Using the wrong software on a different controller (like Phison or Silicon Motion) can permanently "brick" the device.
To verify your chip, download a free utility like ChipGenius or Flash Drive Information Extractor. Look for the "Controller" or "Chip Vendor" field. If it says Alcor Micro, you’re good to go. Step 2: How to Use AlcorMP to Repair Your Drive
Once you have confirmed you have an Alcor chip, follow these steps:
Download the Correct Version: Alcor releases many versions of their MP tool. Look for the version that matches your specific chip model (found via ChipGenius). The Alcor Recovery Tool (often referred to as
Run as Administrator: Right-click the .exe (often named AlcorMP.exe or Load.exe) and run it with admin privileges.
Insert Your USB Drive: The tool should automatically detect your drive in one of the numbered "slots" on the interface. If it shows a yellow or green box, it has recognized the hardware.
Configure Settings (Optional): Most users should stick to the default settings. However, you can click "Setup" (password is usually blank) to adjust the "Scan Level" or "ECC" settings if the drive is heavily corrupted.
Start the Process: Click the Start (S) button. The tool will begin a "Low-Level Format." It will scan for bad blocks, re-write the firmware, and create a fresh partition.
Completion: Once the box turns green and shows "OK," unplug the drive and plug it back in. Windows should now recognize it as a brand-new, empty drive. Risks and Limitations
While the Alcor Recovery Tool is powerful, keep these points in mind:
Data Loss: This is a destructive process. It wipes everything. Do not use this if you are trying to recover files; use it only to repair the hardware.
Hardware Failure: If the NAND flash memory chip inside the USB is physically cracked or "burnt out," no software can fix it.
Complexity: The interface is often technical and sometimes lacks an English translation, making it a bit intimidating for casual users. Conclusion
The Alcor Recovery Tool is the "last resort" for Alcor-based USB drives. When Windows formatting tools fail, this factory-level software provides a way to re-initialize the controller and squeeze more life out of your hardware. By correctly identifying your controller and using the appropriate version of AlcorMP, you can turn a "paperweight" back into a functional storage device.

Industrial Maintenance: Mass-configuring multiple drives with specific vendor or product IDs.
This document outlines the features and technical specifications for an Alcor Recovery Tool.
Given that "Alcor" most commonly refers to the Alcor Micro USB Card Reader controller (widely used in USB flash drives, SD card readers, and embedded storage solutions), this specification focuses on a utility designed to diagnose, repair, and recover data from storage devices running on Alcor Micro (Alcorlink) chipsets.
Before using the Alcor Recovery Tool, you must confirm that your USB drive contains an Alcor Micro controller. Using the wrong manufacturer’s recovery tool can permanently brick your device.
Method 1: Use ChipGenius (Windows)
Download and run ChipGenius (a free utility). It will display:
Method 2: Check VID/PID
Open Device Manager → Universal Serial Bus devices → Right-click your USB drive → Properties → Details → Hardware Ids.
Alcor controllers typically have VID = 058F (Alcor’s vendor ID). For example, USB\VID_058F&PID_6387.
Common Alcor Controller Models:
If you see VID: 058F, you are likely safe to proceed with the Alcor Recovery Tool.
This is the most confusing part for beginners. There is no single "Alcor Recovery Tool." The correct version depends on your controller chip model.
Via “Set LED” under Advanced settings, you can change how the activity light behaves (e.g., always on, blink on read/write).
No. The Alcor Recovery Tool is a factory-level utility. It is not meant for routine formatting. It should only be used when:
Using it on a healthy drive can unnecessarily wear out the flash memory and reduce its lifespan.
