Okay, so I have configured freenas a while ago just to check it out and see if it was right for me. Everything was working, and I was happy. I tested the power usage, and I didn't like that at all. I installed it on an old iMac and I couldn't get the screen to turn off either. Now, this was fine by me, not the fault of FreeNAS, just my personal preference, so I stopped using FreeNAS. But when I tried to use the Hard Drive that I had used for FreeNAS on my windows machine, I couldn't get it to work, I've tried multiple software to repartition it so I can use it on windows, and when those didn't work, I tried using the command prompt, I've searched though half of the internet by now, but can't find anything. I used the hard drive for FreeNAS 9.3.1 Stable, and I think that would format it in the ZFS file system, but i'm not sure. If anyone could help me, I'd be more than happy to provide any other info if necessary.
