MP 7,1 Fusion Flex J3i disconnecting on Mac Pro 7,1

[typecase]

Hi,

I just got the Mac Pro and installed the Sonnet Fusion Flex J3i. This allowed to install 3 drives from my cheesegrater MP to the new machine. The two SATA drives stay connected but some of them don't mount occasionally (like one in 5 reboots, one of the drives won't mount). The other problem and the more urgent issue I'm facing is that the SATA-->USB connected drive keeps disconnecting. I have a feeling it's related to an energy saving setting or something. Anyone else with this configuration experiencing this or have any solutions. I have emailed Sonnet's support line but haven't heard anything back yet. Any help appreciated.

Lou thanks for pointing me in the right direction. That helped a lot.

As flowrider pointed out, the problem with the USB connection is almost surely the cable, as some J3is shipped with faulty USB to SATA adapters, so buy a new one or ask Sonnet for a free replacement. About the SATA drives, are they the same brand / model? I also had a problem with one drive (a WD gold) not mounting after restart (but it did after cold boot). In my case I think it was the drive itself that had problems, maybe due to slightly incompatible firmware. Using a different HDD (in this case: 2x WD Red) solved this problem.

Sonnet is being great about it and shipped me a new cable overnight. Hopefully this solves the problem. The SATA drive not mounting isn't too big a deal as reboot usually solves it and it never disconnects again while the PC is on or sleeping. The only risk of a disconnect is at another fresh boot, and it usually mounts. Thanks for the tip on the drive though. I will look into replacing it soon.
