How to format USB stick showing CDFS

[phr4n]

I found a 16gb USB when I was sorting through a drawer, stuck it in my pc expecting to format but the option isnt there. the stick shows as a CD Drive with a U3 system installed on it. It shows 6mb of space with 0 free. Tried looking at it in the Disk manager, no options for format. Anyone got any ideas on how to free up the space on here / format?

My U3 drive shows up as 2 drives.
1 is the U3 boot drive and 1 is the actual storage drive.
Are you seeing 2 drives when plugging it in?

In my computer it shows another removable disk on my USB hub, but there's nothing there when I try to open or click properties.

Also in Disk Management it only shows the 6mb partition, nothing else.

If the U3 was password protected you might not be able to see the storage partition.
If you run the U3 drive, do you get the U3 software popup?

You can remove the U3 system: http://u3.sandisk.com/launchpadremoval.htm
Once you've done that you should be able to treat the stick like any other.
