Unplug all other USB drives so you do not accidentally erase the wrong one. 3. Run AlcorMP as Administrator
: If the tool detects many bad blocks during repair, your drive's total capacity may decrease (e.g., a 32GB drive might become 6GB) to ensure the remaining memory is stable. Operating System : These tools are often highly sensitive and work best on Windows 7 or 10 (32-bit) environments. identifying your specific Flash ID
| Issue | Likely cause | Solution | |-------|--------------|----------| | Tool shows “No Device” | Wrong PID/VID, or USB 3.0 port | Use USB 2.0 port; edit AlcorMP.ini to add VID/PID | | Format fails at 99% | Bad NAND or wrong tool version | Try older/newer AlcorMP version | | Capacity shows 8 MB after repair | Firmware mismatch | Find exact match using Flash ID in tool database | | Drive still read-only | Physical NAND write-protect or dead chip | Replace drive |
Physically open the USB casing and look for the chip identification number. AU6989SNGTC Go to product viewer dialog for this item. alcor micro usb repair tool au6989sngtc au6998sn link
(database + tools):
The tool should show a box representing your USB port (e.g., FC1-CH1). If it is purple or white, it detects the drive.
: Curated by independent developers, these builds offer automated VID/PID reading, preset optimizations, and multi-language support. These are highly effective for consumer repair scenarios and are hosted directly on the AlcorMP MD Modification Directory . ⚙️ Step 3: Configure the Flash Utility Unplug all other USB drives so you do

The Alcor Micro USB Repair Tool—frequently referred to as or AlcorMP_UFD —is a low-level factory flash-programming tool. Unlike standard formatting tools, this software interacts directly with the flash controller (e.g., AU6989SNGTC Go to product viewer dialog for this item.
和 AU6998SN 是同一家族中紧密关联的两个型号。在实际检测中，ChipGenius等工具往往会将二者并列为同一行输出，例如 “AU6989SN-GTC/AU6998SN [F500]”。这是因为AU6998SN实际上可以看作是AU6989SN系列的衍生产品——它集成了非常相似的核心架构，但在固件支持和闪存兼容性方面针对更新的NAND Flash颗粒做了优化。两者共用同一套量产工具生态，在量产操作和修复方法上基本完全一致。
