Hi, I've got a 1tb spare HDD and was using it for a backup drive. I wanted to delete the contents and did so. The usual message of "this file is too big to transfer to the recycle bin, do you want to permanetly delete it" came up and I clicked delete. Now in my computer it's showing that there is still 33gb still being used, but nothing in the drives contents ... what do I do from here to erase everything on that drive ???
