Once you have the VID and PID, you can search for the specific manufacturer. For example, a VID of 058F usually indicates Alcor Micro, while 1E3D often points to ChipsBank. You will need the "MMP" (Mass Production Tool) associated with that manufacturer, which typically includes the needed to talk to the NAND controller. Step 3: Manual Installation
Select and click Next to reinstall it. 2. Manage Drive Letter and Partitions
The phrase refers to a specific hardware identifier often seen in Windows Device Manager when a USB flash drive is connected. While "NAND" is the standard non-volatile storage technology used in almost all modern flash drives, the "USB2DISK" string is frequently associated with generic or unbranded storage controllers.
By following the troubleshooting and repair steps outlined in this guide — from checking physical connections and removing conflicting drivers to running ChipGenius and applying the appropriate mass production tool — you can salvage many NAND USB2DISK devices that would otherwise be considered e‑waste. Remember that prevention is the best strategy: verify new USB drives immediately, always eject safely, and purchase storage media from trusted sources. nand usb2disk usb device driver exclusive
I can give you the specific download name and settings needed to reflash your controller. Share public link
Download and run a partition tool like or MiniTool Partition Wizard . Locate your NAND USB2Disk drive in the visual disk map. Right-click the partition and select Wipe Data or Format .
Remember: When a driver claims "exclusive" access, it is telling you that something else is holding the door shut. Your job is to find that lock and cut the key. Once you have the VID and PID, you
Check the manufacturer's website (if known) for the specific driver download. Update Driver via Device Manager: Open Device Manager. Locate the device under "Universal Serial Bus Controllers". Right-click and select "Update Driver" . Choose "Search automatically for drivers."
Do you have the values for your device, or would you like help identifying the manufacturer based on those codes?
Using an MP Tool to flash or low-level format the NAND memory controller will permanently delete all data on the device. If data recovery is your primary goal, avoid flashing tools and instead use direct physical NAND extraction services. Step 3: Manual Installation Select and click Next
When a driver is marked as it means the operating system or a specific application has locked the device to prevent other processes from accessing it simultaneously. Key Characteristics
Here is a comprehensive guide to understanding, troubleshooting, and installing the NAND USB2Disk driver safely. Understanding the NAND USB2Disk Architecture
Have you successfully recovered a drive using this method? Let us know your controller chip ID in the comments below
For advanced users, tools like ChipGenius can identify the exact "Controller Vendor" (e.g., FirstChip). You can then search for "MpTools" (Mass Production Tools) specific to that controller to try and re-flash the firmware. Warning: This will permanently erase all data on the drive.
