I want to revert the flash drive to one single volume but could not. When I right-clicked on the two small volumes, the function 'Delete Volume' is slightly greyed. Nothing happens when I click on it......When I tried to Format, it would only format to its current volume size of 49 MB. The Format button for the 99 MB volume is greyed and not working. - Microsoft
