This report details the technical specifications and repair procedures for USB flash drives utilizing the Alcor Micro controllers AU6989SN-GTC and AU6998SN. These controllers are commonly found in generic, OEM, and branded USB storage devices. The focus of this report is on the "Mass Production Tool" (MP Tool), which is the primary software utility used to restore, format, and repair these devices when they become corrupted or unusable.
| Feature | AU6989SN-GTC | AU6998SN | |---------|--------------|-----------| | Interface | USB 2.0 | USB 2.0 | | NAND support | SLC, MLC, TLC, 3D NAND | Older MLC/SLC | | Max capacity | Up to 256 GB (theoretical) | Up to 128 GB | | Common uses | Generic USB drives, card readers | Older USB 2.0 drives | | Tool family | AlcorMP (version 6.21 – 6.24+) | AlcorMP (version 6.18 – 6.21) |
These chips are often misdetected by Windows as a generic “Alcor Micro USB Reader” or “USB Mass Storage Device.”
If you cannot find a working Alcor Micro USB Repair Tool AU6989SNGTC AU6998SN link due to DMCA takedowns, consider usbflashinfo to read the exact firmware version, then use nv3_flasher (Linux only) which supports Alcor controllers via reverse-engineered USB commands.
The Alcor Micro USB Repair Tool is used for repairing, formatting, and configuring USB devices that utilize Alcor Micro chipsets. The tool can help resolve issues such as:
The Alcor Micro AU6989SN-GTC and AU6998SN are mature USB 2.0 controllers whose repair requires the correct version of AlcorMP. Successful restoration depends on identifying the exact controller and flash type, using the matching tool build, and following low-level formatting procedures.
For reliable repair:
Report compiled March 2025 – AlcorMP versions evolve, but core principles remain unchanged for AU6989SN and AU6998SN controllers.
Do not rely on the sticker on the USB casing. Open the drive carefully or use software:
If ChipGenius returns VID 058F PID 6387 or Controller: Alcor Micro AU6989SN-GTC / AU6998SN, you are in the right place.
Alcor Micro Corp. is a prominent Taiwanese fabless semiconductor company specializing in USB flash drive controllers.
When a flash drive using these controllers fails (e.g., "Please Insert Disk" error, 0 bytes capacity, or write protection errors), it is typically due to firmware corruption or a mismatch between the controller and the NAND flash parameters. The repair tool re-flashes the firmware and reconfigures the controller parameters.
Step 1: Install the Driver
Step 2: Open AlcorMP.exe
Step 3: Configure Settings (Crucial)
Step 4: Start the Repair
Step 5: Eject and Replug
