Prevention: How to Avoid “Unknown Device” Errors in the Future

• Always safely eject your USB drive.
• Avoid cheap, no-name flash drives from online marketplaces — they often use fake controller IDs.
• Back up important data to cloud storage or an external SSD.
• Update your motherboard chipset drivers regularly.

10. Frequently Asked Questions (FAQ)

Q: Is AU87101A UFDISK a virus? A: No. It is a symptom of firmware failure. However, a virus can cause the corruption that leads to this error. au87101a ufdisk

Q: I ran the MPTool and now the drive is even smaller (e.g., 32GB became 8GB). Why? A: The MPTool detected bad blocks on your NAND chip and "blocked them out." Your drive's usable cells have degraded. It is time to buy a new drive.

Q: Can I fix this on a Mac? A: MacOS will also show the drive as unidentified. Use Disk Utility -> First Aid. If that fails, you must use a Windows PC for the MPTool, as MacOS does not support these low-level USB flashing utilities.

Q: Does this work for SD cards? A: No, "AU87101A UFDISK" specifically refers to USB flash drives. SD cards have different controllers (though they can also show generic errors like "Generic Storage Device").

Step 4: Fix USB Root Hub Power Settings (Overlooked but Effective)

Windows sometimes cuts power to unrecognized devices.

1. Go to Device Manager → Universal Serial Bus controllers.
2. Right-click each USB Root Hub → Properties → Power Management tab.
3. Uncheck "Allow the computer to turn off this device to save power".
4. Click OK and restart your PC.

7. Method 3: Fixing via DiskPart and Windows Utilities

If the Mass Production Tool is too intimidating or the drive still shows the correct capacity (e.g., 32GB), you might simply have a partition table error, not dead firmware. High-Performance Controller : The AU87101A UFDisk features a

Step-by-step guide:

Step 1: Identify the true controller. Download ChipGenius (Windows). Run it. Look at your AU87101A drive. It will reveal:

• Controller Vendor: Alcor Micro
• Controller Part-No: AU87101A (or similar, like AU699X, AU87102)

Step 2: Download the correct MPTool. Search Google for: Alcor AU87101A MPTool. Look for version 1.2.x or newer. Be careful of virus-laden sites; use reputable firmware repositories (like USBDev.ru or FlashBoot.ru).

Step 3: Run MPTool as Administrator. Extract the zip file. Right-click MPTool.exe -> Run as Administrator.

Step 4: Configure the settings.

• Click "Setup" or "Parameter Setting."
• Password is often blank, 123, or 320.
• Uncheck "Auto Run" if present.
• Under "Flash Type," let the tool auto-detect if possible. If not, match the NAND ID seen in ChipGenius.
• Crucially: Ensure that "Erase All" or "Full Factory Format" is selected. Do not select "Test Only."

Step 5: Flash the firmware. Click "Start" or "Run." The tool will: Benefits of AU87101A UFDisk

1. Erase the corrupt firmware.
2. Write the new low-level firmware.
3. Re-initialize the NAND flash.
4. Re-verify the drive.

The process takes 5–20 minutes. Do not unplug the drive during this process.

Step 6: Post-repair. Once the tool says "OK" or "Pass," close the tool. Unplug the USB drive. Reboot your PC. Plug it back in. Your drive should now appear with its correct name and capacity.
