I don't like posting help topics all the time, but I really need some help here guys. A couple of months ago, my main hard drive started to act up when I recently installed a new battery. Unfortunately, it just died all together, and would not boot up. It took a while for me to get everything situated on the back up drive, and I found out that I can still explore the other drive from my back up drive, and manually delete most things..... Except for some files, which seem to be important files for that drive's installed OS. (Both have Windows 7. I was given 2 keys for it when I paid for one.) My problem is this. I would like to keep both drives, but no matter what I do, windows will not allow me to format it, even though I am the administrator. I can't even do it while in safe mode, and with command prompt. I would greatly appreciate some help. I've searched for weeks on the internet but have found no solution.
