Hello, I am a student working for a university physics lab, and we have a worthless IT guy, so I'm pretty much on my own to deal with this. I recently built a computer for my boss with two hard drives for which we want to set up a RAID Mirror Array. After putting the parts together, my boss managed to get our IT guy to install Windows 7 on the machine. This was a one-in-a-million occasion, as our IT guy is impossible to get a hold of, never in his office, and just generally avoids work. He said that he would set up a RAID array on the computer, but instead he just set one hard drive to back up to the other every day at noon, which leaves me to try to set up the hard drives correctly. I've been following the tutorial here: How to Create a Software RAID Array in Windows 7 - How-To Geek and got to the step where I would right-click on the unallocated space and click "New Mirrored Volume..." However, I can't do this because even though I've deallocated most of the space on the disk, it still has a System Reserved 100MB NTFS partition which I can't do anything about: http://img18.imageshack.us/img18/7533/dskmngscrcap.png Is there any way I can deal with this other than reformatting the hard drives and reinstalling Windows 7? I don't have the disks, and our IT guy is so difficult to get to do anything, that could take weeks. Thank you for any help.
