How to Repair a Write-Protected Flashdisk in v2.9.1.1 Format Using a Zip File

A write-protected flashdisk is a USB storage device that cannot be modified or deleted by the user. This can be caused by various reasons, such as a physical switch, a virus infection, a corrupted file system, or a software setting. If you have a write-protected flashdisk in v2.9.1.1 format, which is a proprietary format used by some USB flash drives, you may encounter difficulties in repairing it using conventional methods. However, there is a possible solution that involves using a zip file to bypass the write protection and format the flashdisk to a standard format.


What You Need

  • A write-protected flashdisk in v2.9.1.1 format

  • A computer with Windows operating system

  • A zip file containing the following files: Ufix-V.exe, Ufix-V.ini, and Ufix-V.dat

What You Do

  • Download the zip file from [this link] and extract it to a folder on your computer.

  • Insert your write-protected flashdisk into a USB port on your computer.

  • Run the Ufix-V.exe file as an administrator from the extracted folder.

  • Select your flashdisk from the drop-down menu and click Start.

  • Wait for the process to complete. It may take several minutes depending on the size and condition of your flashdisk.

  • Once done, you will see a message saying "Format Complete". Click OK and exit the program.

  • Eject your flashdisk safely from your computer and check if it is working normally.

What You Should Know

  • This method will erase all the data on your flashdisk, so make sure you have a backup of any important files before proceeding.

  • This method will also change the format of your flashdisk from v2.9.1.1 to FAT32, which is compatible with most devices and operating systems.

  • This method may not work for all types of write-protected flashdisks in v2.9.1.1 format, depending on the cause and extent of the write protection.

  • This method is based on the USB Flash Driver Format Tool Ufix-V, which is a freeware developed by PNY Technologies Inc. for their flash drive products.


In this article, we have shown you how to repair a write-protected flashdisk in v2.9.1.1 format using a zip file containing the Ufix-V tool. This is a simple and effective way to bypass the write protection and format the flashdisk to a standard format that can be used normally. However, this method may not work for all cases and may result in data loss, so use it at your own risk and discretion.
