I'm trying to format a 1TB HDD secondary drive but the option is not available through Disk Management. When I right-click on the "healthy" volume, the format option isn't available. I only get Open, Explore, Shrink Volume, Change Drive Letter, Properties, and Help

I also can't get the two unallocated sections to combine, even after creating a new simple volume with one, they both turn to simple volumes. I do anything to one of the unallocated section, and the other does the same.

I try using the format option from right-click on the drive through My Computer and I get:

"Windows cannot format this drive. Quit any disk utilities or other programs that are using this drive, and make sure that no window is displaying the contents of the drive. Then try formatting again."

I don't have anything open for it or running from it, that I know of. I deleted all visible contents from the drive, but there is still 3.93 GB of something hidden from me. I just want to completely wipe the whole drive and start over with it.
 
Please make sure you select the right Disk or you will loose all data


run diskpart

list disk //this should show you a list of all disks currently connected to the computer
select disk # //this will collect the disk you want to work on, substituted the # with the number of the drive you want
clean //this will delete all data and partitions of the currently selected disk
exit //this will exit diskpart
