I have a new one for ya concerning eSATA; anyone using eSATA yet?

I'm using an eSATA enclosure for backups and it seems that the drive doesn't appear in the 'Safely Remove Hardware' option in the systray. I know it's not USB, but in older systems I've seen it where you can add/remove SATA devices this way (namely the nForce-based systems).
Does anyone think that by just turning off the enclosure that it will screw up the drive/data at all? The only other thing I can think of would be dismounting it via command prompt, but it still shows up under 'My Computer' that way.

Any thoughts/ideas/suggestions?
TIA!
