cMP 1,1 / inatek 4006 problems

[Ultracyclist]

Hi,

Im having some trouble with the USB 3.0 on my cMP.

OS: 10.11.5
Mac: cMP 1,1 (2,1)
SSD: 250GB Samsung Evo 850
RAM: 32GB
GPU: Sapphire 7950 3GB

-------------------------------------------------------------------

Upon installing the PCI - no problem
When inserting a USB 3.0 external SSD or thumb drive it see's them and i can format the drives, but when i try writing to them they crash. Ive done the same steps on a USB 2.0 port and the drives are fine.

When crashing the drive become "unusable" and are faulty removed (not by me, but by the Mac)

Anyone with the same problems? Or better yet a solution?

Jeroen

Check the cable, I've seen similar situation. End up is the connector's problem. Once I PULL the connector 1-2mm away from the USB 3.0 port (not fully inserted). The external work perfectly.

What connector do you mean? the USB connector from the external drive?

The connector on the cable that plug into the card's port.

Same result over and over again. Please help!

Dear Jeroen,
these SSD/thumb disks use the power of the USB-connection, I suppose. Might that be the problem? Maybe Your PCI-USB-Card does not supply enough power to write to those disks.

Perhaps you just have a faulty card.

Do you have another OS to try? Either Windows, or a fresh install of OS X (preferably not El Cap)? To rule out software as the problem.

About two months ago, I had one of these cards go bad on me. Sometimes external drives would mount, sometimes they would not. I ended up just getting a new non-branded USB 3 card based on the FL1100 chipset from Ebay.

Thanks for your input,

Could give a external power cord I have lying around a try. I had an Usb 3.o card before but that wasn't supported at all when i tried the external power I got kernel panic at boot.

I don't have a other partition on the Mac, and I don't use windows , so checking a software error won't go.

Just did the same after reading your post. But will check with the power cable non the less.
