25) Can I install FreeNAS on a hard drive?
FreeNAS isn't intended to be installed on a hard drive, you can do it, but if you do you can't resize the partitions or use the disk for any other purpose. The partition sizes with FreeNAS are fixed and no matter what the size of the disk you install it on, *anything* after 2G is unusable. FreeNAS doesn't just live on 1 partition, it creates/uses 4 partitions, but they are not the standard DOS filesystem type. It's a completely different partition table type than DOS/Window/Linux, so they're not compatible or able to be shared.
