I have a Mediasonic ProBox HF2-SU2S2 4-bay USB 2.0 external enclosure with four 1-terabyte hard drives inside. I tried plugging this unit into the red eSATA port of my Z77 Extreme6 board, but it would not activate (it checks for a proper connection, and if not, it automatically shuts down).
This enclosure will only operate with my board when I use a USB plug. As it turns out, they specify that the motherboard must be port-multiplier-compatible:
So, is the eSATA architecture of the Z77 Extreme6 board port-multiplier-compatible, or is the eSATA port capable of handling only one eternal hard drive?

Note: Motherboard's SATA port MUST support Port Multiplier in order for your computer to recognize multiple hard drive if the unit is connectd via eSATA.
Important Note: When connecting via eSATA interface, customer's computer hardware needs to have Port Multiplier w/ FIS-based switching in order to access multiple HDDs simultaneously.
