Lacie USB3.0 PCIe + WD MyBook - Not working

[TomTomTuning]

I recently had another thread talking about issues with a generic NEC USB3.0 card. I never did get it working, so I wound up selling that card and buying a Lacie card, unfortunately I'm still having issues. The only USB3.0 devices I have are WD MyBook Essentials external drives....So here's whats going on.

Installed the most recent Lacie Drivers :

Updated MyBook Firmware and installed WD Mac+Turbo Driver: http://support.wdc.com/product/download.asp?groupid=125&lang=en

The drive does not mount when connected to USB3.0 port. Nor does it show up in System Info or Disk Utilities.
As soon as I turn the drive on my wireless Magic Mouse starts lagging horribly.
When I connect the drive to a USB2.0 port it works fine.

I called WD and they've decided to send me a new "correct" USB3.0 cable.
I have three of the same drive which mean I have three cables and none of them worked..

Any help is appreciated.

EDIT: Agh, I just called Lacie and they told me their PCIe card will only work with Lacie hard drives.
Anyway around this?

Hmmm... I was able to get the drive to mount, but still having issues.

I installed patched .Kext 1.0.10

But I could not perform any speedtest (Black Magic) or even write files to the drive, it would just lock up.



So I then tried patched .Kext 1.0.8
http://www.osx86.net/downloads.php?do=file&id=2870

And the drive would not mount, but showed up only in System Information.

I decided to try Multibeast to see what version of the patched .Kext file it was using but unfortunately it was 1.0.10, so no improvement.


Before I called Lacie I posted on their facebook page and they replied:

Tom, The card can and will mount any non LaCie drive as USB 2.0. Our drivers are for LaCie USB 3.0 drives but any should mount anything as at least USB 2.0. Have you downloaded and installed the 10.8 drivers? If you had the card installed before you updated to ML then the drivers need to be updated manually. The process involves rebooting the computer and reseating the device. After that we would need to confirm the card with another drive and/or another computer to ensure it hasn't become defective or damaged.
