You don't need to know any commands whatsoever - everything you need is right there. I'm guessing that you can't format the drives because they're using some funky Linux file system. To make use of them through the installer, you'll have to:No I tried,but I don't know command prompt at hirens boot cd format disk area.
- Delete the partition/s
- Create a new partition/s using the free space
- Format it/them to NTFS
