WIn 7

I want to delete the WIn 7 files off my 2nd HDD (use to be my main in my other computer) with out having to lug the 400 GB over to 1 HDD, format, then move it all back. It won't let me just manually remove the folder with a simple right click/delete. Everything else I wanted off worked fine, but nothing windows based...

i used this to remove any un needed partitions on my old HDD should work for u too...

try to use super admin account if windows wont let you do it from there too then use portable linux ( http://www.pendrivelinux.com/ ) I use it when can't remove or move some windows files), take a few mins to download it, there are versions for cd and pendrive as well, no need to install on hdd quite usefull when windows is dead and I got important files which would be gone after OS reinstallation.
