Why can't I see HDDs connected to my IBMServRAID M5014 controller?

I purchased an IBM ServRAID M5014 controller card and am trying to connect it to 8 drives via two SFF-8087 breakout cables. All drives have power and good SATA cable connections. This RAID controller card, from what I have read, is identical to the LSI MegaRAID 9260-8i card. The drives I am using are  1 TBWD 1003FBYX Enterprise class drives that were pulled from a working system, so I feel confident that the drives are good.

So all cables attached, I can feel motion inside the drives, latest Windows 2008 drivers have been installed. Card is shown in Device Manager and I can get into the RAID utility on pre-boot when I start my computer. I can also get into the card's software via the MegaRAID Storage Manager application. I can browse through the software and see that the card is online and functioning.

However, the card does not see any of the 8 drives that I have attached to it. As I mentioned, I can feel heat from the drives and can feel the spinning motion, so I know the drives are powered on. I have downloaded and attempted to install the latest firmware from both the LSI and IBM websites, but when I try to update the firware, it tells me that it is not the correct version.

I can't seem to figure out why the card cannot see the drives.

Any suggestions?

Thanks in advance.
