Powered eSATA Enclosure Does Not Mount
Certain eSATA enclosures/drives may experience difficulty mounting onto the desktop when “hot plugged” into
the eSATA Hub. For example, an eSATA enclosure connected to a powered eSATA Hub is not available on the
desktop. Further, it cannot be mounted from the Mac Disk Utility. If you encounter such a case, please follow the
instructions below:
Confirm that the eSATA enclosure power switch is set to On rather than Auto. Certain eSATA enclosures

include an Auto mode that powers on the device when it receives a signal from the computer. This setting
will effect performance when connected to the eSATA Hub.
