Hi everyone, I have a gigabyte GA-Z77-DS3H motherboard and it only has 4 SATA ports. I would like to add some more, and I have a Rosewill RC-216 RAID card with 2 internal and 2 external SATA ports. It is recognized by the BIOS along with drives I connect to it, but they don't show up in OSX.

Does anyone have any recommendations on how to make this card work, or another card that I could buy that would be compatible?

It was recommended to use Multibeast to install the 3rd Party SATA driver, which I did to no avail. However, when looking in the system profiler/system report, the card actually does show up as JMicron JMB363 AHCI now, with a 3 GB/s speed. Just no drives showing up in OSX. Here's a pic of the SATA section of system report:

Thanks a lot
