If you connect an eSATA device after the computer has already been
turned on, it will take about ten seconds for it to be recognized by the
computer.
Do not attempt to disconnect and reconnect the drive before this period
has elapsed.
A connected eSATA device may not be recognized if it is connected to the
computer's eSATA/USB combo port while the computer is in Sleep Mode
or Hibernation Mode. If this occurs, disconnect the eSATA device and then
reconnect the device while the computer is turned on.
