I have the Corsair 512mb flash drive and hooked up a USB floppy drive to make the USB drive bootable. I used the HP drive key boot utility and was able to boot from the flash drive but now from windows explorer when I click on the flash drive it says "please insert a disk in drive x"

you may have to format it. Right click drive and select format. See if that helps.
I tried to format first thing...didn't work.
I did install the memtest utility on this flash drive if that means anything.
