I'm thinking about picking up an eSATA enclosure and sticking a drive in it for backup. I have 6 SATA ports on my motherboard. If I use one of those internal to external adapters, will windows see the eSATA drive as removable like a USB or Firewire drive? I want to turn this drive on only when its being used and turn it off when I'm done, without having to shutdown/restart the computer. I'm running Vista.
