How do I get rid of "U3 System" on my USB drive?

The solution came from u3_tool (universe), which can:

• uninstall the U3 software
• reclaim the CD-ROM disk space
• run on Ubuntu

I ran sudo u3-tool -p 0 /dev/sdb and then repartitioned the drive. Now it mounts like a "normal" USB drive.

U3 is proprietary software that SanDisk loads on it's USB drive. It runs in a partition you can't reformat, or really detect, and it'll likely always be there.

If you have a Windows machine you can run the Un-installer using the guide in the SanDisk KB.

U3 Uninstaller is windows only. Available here:

I know of no way to do this in Linux.
