AlcorMP works best on Windows XP (32-bit).
On Windows 7/8/10/11, you must:

  • Run as Administrator.
  • Disable antivirus real-time protection (AlcorMP writes directly to disk sectors – AV may block it).
  • Do not run from a network drive or cloud-synced folder (use C:\AlcorMP).

    • In the world of USB mass storage controllers, few names are as ubiquitous yet as cryptic as Alcor Micro. For technicians specializing in flash drive recovery, low-level formatting, or PID/VID customization, the string "alcor+mp+200717+install" represents a specific, critical junction. This combination of keywords points directly to a particular firmware version (200717) of the Alcor MP (Mass Production) tool.

    If you are staring at a bricked USB drive, dealing with a “Write Protect” error that won’t go away, or trying to resurrect an old 2.0 or 3.0 flash drive, you have likely landed here. This article will walk you through the exact installation process, driver configuration, and operational nuances of the Alcor MP tool dated 200717.

    What this guide covers:

    If AlcorMP 200717 fails repeatedly:

    AlcorMP 20.07.17 is a specialized firmware flashing and mass production tool (MPTool) used primarily for repairing corrupted USB flash drives equipped with Alcor Micro controllers. Prerequisites & Safety Warnings : This process performs a low-level format and will permanently erase all data on the USB drive. Driver Warning : During operation, the tool installs a temporary driver ( mpszfilt.sys

    ). If the program crashes or is closed incorrectly, this driver may stay active and disable other USB devices like your keyboard or mouse. If this happens, reopen and close the tool correctly to uninstall the driver. Compatibility

    : Ensure your drive uses an Alcor Micro chip (e.g., AU698x series) using a tool like ChipGenius before proceeding. Installation & Execution Steps Download and Extract : Obtain the version from a reputable source like Alcor Infotech . Extract the file to a dedicated folder on your desktop. Run as Administrator : Right-click AlcorMP.exe and select Run as Administrator Select Mode : If prompted upon startup, choose between (for basic repair/bad block scanning) or (for standard production/formatting). Connect Device

    : Plug your corrupted USB drive into a direct motherboard port (avoid USB hubs). The tool should automatically detect it in one of the numbered slots. Configuration (Setup) . The default password is often blank or Flash Type tab, ensure "Auto Detect" is checked.

    tab, verify the VID and PID match your chip's specifications (usually Start Flashing

    to begin the firmware reinstallation. The status bar will turn green once the "OK" message appears. Common Troubleshooting Tool doesn't see USB : Try a different USB port or restart the software. Write Protection

    : This tool is frequently used to fix "The disk is write protected" errors by overwriting the corrupted firmware flags. Error Codes : If you see codes like

    , it often indicates a hardware failure or an incorrect firmware version selection. USB controller's part number to confirm this is the right version for your hardware?

    This guide outlines how to set up and use the utility to fix common issues like "disk is write protected" or drives that are no longer recognized by Windows. 1. Preparation and Prerequisites

    Before starting, ensure you have the correct software environment to avoid driver conflicts.

    Operating System: It is highly recommended to use a 32-bit version of Windows (e.g., Windows XP or Windows 7), as these utilities often have stability issues on 64-bit systems.

    Identify Your Controller: Use a tool like ChipGenius to verify that your flash drive actually uses an Alcor Micro controller.

    Warning: This process involves a low-level format. All data currently on the flash drive will be permanently erased. 2. Installation and Initial Setup

    The AlcorMP tool usually comes as a portable application in a .zip or .rar archive.

    Unpack: Extract the files to a local folder on your hard drive (avoid running it directly from a zip file).

    Configuration Backup: Before the first run, it is wise to backup the default AlcorMP.ini file located in the program folder.

    Driver Warning: The tool may install a temporary driver (mpszfilt.sys). If the program crashes, your USB ports might stop working until you restart the tool and close it properly to trigger the uninstallation of this driver. 3. Running the Tool

    Launch: Run the executable (usually AlcorMP.exe) before plugging in your flash drive.

    Connect Drive: Insert the flash drive into a USB 2.0 port (front-panel ports or USB 3.0 ports can sometimes cause detection failures).

    Detection: The drive should appear in one of the numbered slots in the main window.

    Setup (Optional): Click Setup (S). If prompted for a password, it is typically left blank. Here you can: Change the VID/PID identifiers.

    Set the ECC (Error Correction Code) level to optimize for speed or reliability.

    Configure partitions (e.g., creating a virtual CD-ROM partition). Start: Click Start (A) to begin the recovery process. 4. Troubleshooting Common Errors

    Flash Drive Not Detected: If the utility doesn't see your drive, you may need to manually add your drive's VID and PID to the AlcorMP.ini configuration file.

    Too Many Bad Blocks: If you receive a "50400: Too many bad block" error, try increasing the ECC level or reducing the "Optimization" settings in the Setup menu.

    Safe Removal: Always wait for the process to complete fully before unplugging the drive. Use the Eject button within the AlcorMP interface if available. Resources

    AlcorMP (Последняя версия ALCOR U2 MP v23.08.07.00.H)

    The AlcorMP 20.07.17 is a specialized mass production (MP) tool used to format, repair, or restore USB flash drives that use Alcor Micro controllers. This specific version is often sought out to fix "Disk Write Protected" errors or to restore "Generic USB Flash Disk" devices that are no longer recognized by Windows. Prerequisites Before Installation

    Identify Your Chip: Use a tool like ChipGenius or Flash Drive Information Extractor to confirm your USB drive uses an Alcor controller (e.g., AU6989SN, AU6989AN).

    Backup Data: This process will permanently delete all files on the USB drive.

    OS Compatibility: These tools run best on Windows 7 or Windows 10 (run as Administrator). Step-by-Step Installation & Setup

    Extract the Files: AlcorMP typically comes as a .rar or .zip archive. Extract the entire folder to your desktop. Avoid running it directly from the zip.

    Launch the Tool: Look for AlcorMP.exe or LoadDriver.exe in the extracted folder. Right-click and select "Run as Administrator."

    Insert the USB Drive: Plug in the faulty flash drive. The software should automatically detect it in one of the numbered slots (e.g., "01").

    Note: If it doesn't appear, try clicking the "Refresh" (R) button or check the "Setup" menu to ensure the driver is loaded. Configure Settings (Setup):

    Click the Setup (S) button. If prompted for a password, leave it blank and hit Enter. Under Flash Type, most users can leave this as "Auto."

    Under Optimize, choose "Capacity Prior" (for maximum storage) or "Speed Prior" (for better performance).

    In the Mode tab, ensure "Normal Flash" is selected unless you are creating a bootable partition.

    Start the Process: Click Start (A) to begin the low-level format. Green Bar: Success. Your drive is repaired.

    Red Bar: Error. This usually indicates a hardware failure or a mismatch between the software version and your controller chip. Troubleshooting Common Issues

    "30500: No support flash error": This means the 20.07.17 version does not have the firmware database for your specific NAND chip. You may need a newer or "Online" version of AlcorMP.

    Device Not Found: Ensure you are using a USB 2.0 port. Alcor tools are notoriously unstable when used through USB 3.0/3.1 ports or external hubs.

    Load Driver Failed: Run the LoadDriver.exe found in the folder first, then restart the main application.

    If your drive is completely dead (not detected by Windows but appears as "Unknown Device"), you can perform a boot-circuit install:

    The MP tool requires raw USB access. You must disable Windows’ automatic driver installation:

  • Right-click → Update driver → Browse my computer for drivers.
  • Browse to the folder containing the extracted 200717 files (including the .inf).
  • Click Next – installation should complete in seconds.
  • If prompted about unsigned driver, choose Install this driver software anyway.
