I recently bought a SansDigital TR4M eSata enclosure and installed four drives and conntected it to one of the (NewerTechnology) ports on the back of my early 2008 Mac Pro. I am not using this enclosure for RAID, only to mount four SATA II drives. The problem is only one drive mounts. I have reseated the drives and eSata cable and rebooted several times, but each time, only one drive (the bottom drive in the enclosure) shows up on my desktop. In the product features it says "Access to 4 Hard Drives while using only one cable" so I'm assuming it should be able to mount four drives via the single eSata cable. Note: With the case open and my fingers resting on the top drive, it doesn't "feel" like it's getting power, so I'm wondering if only one drive is mounting because the rest aren't getting power! Any thoughts would be appreciated.
