Formatting a Flash Drive

I have a 1 GB flash drive I wish to format.
When I insert it into the USB port, it comes up in "My Computer" as two separate icons.

One icon is as I would expect, but the other icon is as a disk drive. How can I get rid of the disk drive icon and format the whole thing as one drive with one drive letter?

Nope - sorry.
That didn't work.
I've tried Disk Management and the HP USB Format Tool but neither have solved the problem.

Try going into Control Panel> Admin Tools> Computer Management> Disk Management and format from there.

That's what I just did, rawprawn.
It doesn't format the entire drive, and deleting the unwanted partition is greyed out.

By the way, the unwanted partition comes up as a CD-ROM drive, not as a hard drive.

Have a look at this,Open up your device manager (from control panel) select cd/dvd drives, and then right click the virtual drive that you are having problems with and select unistall then reboot.

Nope - it's still there!

how to remove the CDFS partition & reformat it.

Download this click here,
do a virus scan then run umptool2090.exe, click "settings", tick "need format"
then click the button 2nd from the right at the bottom of the form (the form isn't sized properly as I could only see the top few pixels of the buttons so just tab until you get the correct button).
The settings form will close and the scan mode will show as "high level scan format".
Click the button that displays the drive letter & you should now have a clean drive with 1 partition.

What's the button "2nd from the right at the bottom of the form" labelled?

I don't really know which one you mean.
