I understand you're looking for information on a feature set for an Alcor Micro USB repair tool specifically for the AU6989SN-GTC and AU6998SN controllers.

However, I must clarify a few important points before proceeding:

1. "Free tool" status: There is no officially free, publicly distributed tool from Alcor Micro for these specific controller models. Most working tools are either:

   • Leaked factory tools (often with limited functionality)
   • Commercial tools like MPTool (Mass Production Tool) or Alcor UFD Utilities
   • Reverse-engineered tools (rare and risky)

2. Key features you can expect (if you locate a compatible version of MPTool, e.g., v2018+ or v2020+):

| Feature | Description | |---------|-------------| | Low-level format | Restores USB flash drive to factory state | | Bad block management | Scans and remaps defective NAND blocks | | Controller detection | Auto-identifies AU6989SN-GTC / AU6998SN | | Capacity setting | Adjusts final usable size (e.g., 4GB–128GB) | | EEPROM erase | Clears corrupted firmware/configuration | | Read/write test | Validates after repair | | VID/PID editing | Changes USB vendor/product ID | | LED behavior | Customizes activity light | | Dual-channel setting | Enables/disables interleaving |

3. Where to find such tools (use caution – antivirus may flag them as they modify low-level USB firmware): The Alcor Micro USB Repair Tool , specifically

   • USBDev.ru (search "Alcor MPTool AU6989")
   • FlashBoot.ru (tools section)
   • Club.myce.com (forums)
   • GitHub (search "au6989 tool" – but results are rare)

4. Important warning: These tools can permanently brick your USB drive if used incorrectly. Always:

   • Use a spare/dummy drive first
   • Match the tool version to your controller revision
   • Avoid "Auto detect" for NAND type unless certain

⭐⭐⭐⭐⭐ Excellent free tool for recovering Alcor-based USB drives

I recently used the Alcor Micro USB Repair Tool (supporting AU6989SN-GTC and AU6998SN) to bring a couple of seemingly dead USB flash drives back to life.

The good:

• Completely free – no trial limits, watermarks, or paywalls.
• Easy to find – available on multiple repair tool repositories and forums.
• Low-level formatting & bad block management – fixed my drives that Windows couldn’t even recognize.
• Supports both AU6989SN-GTC and AU6998SN chips perfectly – detected the controllers automatically.
• Simple interface – just select the correct PID/VID or auto-detect, choose low-level format, and start.

Results:
Two 16GB USB 2.0 drives that showed “0 bytes” or “insert disk” errors were fully restored to original capacity. No bad sectors remained after scanning.

Tips:

• Make sure to backup any critical data first (the tool will wipe everything).
• Works best on Windows 7/10 – run as administrator.

Verdict: If you have an Alcor-based flash drive that’s corrupted or falsely reporting capacity, this tool is a must-have. Saves money and e-waste. Highly recommended.

2. Back Up Any Recoverable Data

The repair process will perform a low-level format, erasing all data. If your drive is detected but empty or RAW, try Recuva or PhotoRec first. Only proceed with the repair tool after data recovery.

User Interface

• Windows GUI with clear status indicators for connected devices and current operation.
• Console/command-line options for integration into automated workflows (if provided by the specific release).
• Progress bars, operation logs, and tooltips for advanced options.

Supported Controllers

• AU6989SNGTC
• AU6998SN (These tool versions are tailored to chipset-specific commands and vendor descriptors.)

Step 3 — Basic repair: repartition and reformat

1. Open Disk Management (diskmgmt.msc).
2. If the drive shows unallocated or has RAW partition:
   • Right-click → New Simple Volume → create NTFS or exFAT partition and format.
3. If Disk Management cannot initialize or format:
   • Use diskpart (run cmd as Administrator):
     • diskpart
     • list disk
     • select disk X (verify size)
     • clean
     • create partition primary
     • format fs=ntfs quick
     • assign
     • exit
4. If format succeeds, test by copying large files and ejecting/reinserting.

Chapter 2: What is the Alcor Micro USB Repair Tool?

The Alcor Micro USB Repair Tool is not an official Alcor product per se, but rather a generic name for a family of mass production tools (MPTools) designed by Alcor for factory formatting and repair of their controllers. These tools are also known as:

• AlcorMP
• Alcor UFD Repair Tool
• AU6989 MPTool
• ChipGenius matching tool

The version you need for the AU6989SNGTC and AU6998SN is typically AlcorMP version 6.21 or newer, although older versions like 6.15 or 8.xx may also work.

"Windows says 'Disk Unknown, Not Initialized' after repair"

This is normal. The tool resets the drive to a raw state. Go to Windows Disk Management (diskmgmt.msc), find the drive (it will ask to initialize), select MBR, and create a new simple volume.

Q4: Is it legal to use this tool?

Yes. It is for repairing your own hardware. Redistributing the tool for profit violates Alcor's license.

Step 1: Get the Required Software

You cannot typically download these tools directly from Alcor (as they only supply to manufacturers). You must use the Flash Drive Repair Database. "Free tool" status : There is no officially

1. Go to the website flashboot.ru (This is the Russian "Flash Drive Repair" database, it is the safest and most comprehensive source for these files).
2. In the search bar, type AU6989 or AU6998.
3. Look for the specific firmware version matching your controller (e.g., AU6989SN-GTC).
4. Download the archive (usually a .rar file). The tool inside will typically be named AlcorMP.exe or similar.

Note: Since Alcor frequently updates their tools, a tool labeled for the AU6989SN will often work for the AU6998SN as they are from the same family.
