| The problem is that the controller you've plugged into (the one on
| the motherboard) is not designed for "hotswap" devices.  It's expecting
| a hard-installed drive and thus doesn't have the eject support NOR does 
| it have necessary power supply glitch protection since it's expecting
| its drives to be on the same power supply the motherboard is using.
| 
| It is VERY dangerous to simply connect a motherboard connector to the
| outside world unless it was actually intended for it.  In your case,
| it is quite possible to blow your motherboard if there's an adequate
| ground loop between your computer and the power supply feeding the
| eSATA drive.  An actual eSATA (external SATA) port IS designed for
| hotswap and has the requisite protection.  THOU HAST BEEN WARNED!

Wow.

The drive is installed in a Vantec NexStar 3 NST-360su enclosure:

This enclosure came with an eSATA bracket intended to be connected to
an internal SATA socket.  See page 8 of the users guide (available
from the web page):

	An internal SATA port can be converted to an eSATA port with
	the included adapter.

Do you suspect that the manual is wrong?
