[Solved] Flipping the Removable Media bit — alternatives to BootIt? [closed]

There’s a utility called the Lexar BootIt utility that flips the Removable Media Bit on certain USB flash drives.

I want to flip the bit on my USB flash drive (it’s supported) but really am not too comfortable downloading this utility from random file-sharing sites, nor do I see a license anywhere for it.

The end goal is to recommend a tool for corporate customers so they may flip the bits themselves.

Are there any free or open alternatives to this tool?

Solution #1:

Why would you want to flip the removable bit on your USB Drive?
Which USB Drive do you have?

If you want to partition your USB Flash Drive then you can use Bootice

If you really want to flip the removable bit then you have use Mass Production tools to reprogram the microcontroller in your USB Flash Drive. However this procedure varies for all USB Flash Drives. Most Mass Production tools are used to repair USB Flash Drives or to add or remove CDFS Partition; However, some MP Tools provide the option to Flip the Removable bit.

The general procedure to reprogram your USB Flash Drive to Flip the bit or make other changes is as follows:

Download and Run Chipgenius and find out the VID and PID of your USB Drive.
Edit: (Archived download of chipgenius), (Alternatively use Nirsoft’s USBDeview to get the drive’s VID and PID)

Go to http://flashboot.ru/iflash.html and enter the VID and PID of your USB Drive.Check if there are any MassProduction tools available and download them. Then you will have to figure how to use it.

Check this for detailed guide on how to do this.(In this guide the MPtool is being used to repair a fake USB Drive)

Warning – The procedure varies for different USB Flash Drives and you may end up with irreparable USB Flash Drive.


I have tried flipping the bit of Transcend Jetflash USB Drives with good success. The MPtool for JetFlash USB Drives is called AlcorMptool and this MpTool has the option to flip the removable bit.
Another reason why I feel comfortable to use JetFlash USB Drives is because it can be fixed easily if something goes wrong.

Solution #2:

If you do not want to download a utility from a website that you don’t know, how about compiling your own.

See the codeproject.com article Hooking the kernel directly by Anton Bassov,
containing the sources for a USB filter driver.

I would suggest reading very carefully the entire article and all comments.

The article dates from 2006. It looks like it may still pertain to the latest Windows versions,
but I cannot guarantee this.

Anton Bassov himself seems to be available on LinkedIn (I haven’t tried to contact him).
