    I bought a new SATA Blu-Ray burner for my Mac Pro 3,1, and connected it to one of the two "extra" SATA ports on the motherboard.(you know, the ones behind the fan assembly)
    I booted up the machine running 10.7.3 and inserted a DVD disc into the drive. Nothing happened, no disc visible in Finder. I tried ejecting the drive using the keyboard eject button, nothing happened. I opened the system profiler application, and looked at the SATA devices list. I see my hard drives on the list, but not the Blu-Ray drive. There are 6 AHCI interfaces listed, 4 of them are occupied by hard drives, and the other two I'm guessing are the 2 "extra" ports on the board, one of which I used to connect this new drive.
    Why doesn't the system see the drive? What do I need to do to make this drive work?

    Drive model: LITE-ON IHBS112-04

    Thanks in advance!

    No offense meant, but . . . power cable to the drive?

    None taken. I use a Molex to SATA power adapter :D
    I did say that I inserted a disc... Which I assume would imply that drive has power, in order to open the disc tray.

    As Apple does not support BluRay, maybe the system drivers don't cover your particular drive model?! You could try to zap the NVRAM after having upgraded (found that helpful after graphic cards upgrades) - don't put your hopes too high though.

    I have an LG Bluray drive connected to one of the two extra sata connectors in my Mac Pro 3,1 no issues here. Open the case back up and make sure the sata cables are connected at both ends properly, are you using an extra long cable? It should work.

    It's likely a broken SATA cable OR an unsupported drive (unlikely). Also remember that Apple's ports aren't hot-pluggable (shut down when installing drives).

    The SATA cable is long enough. I'm going to test this drive with this SATA cable on a PC to verify that everything is good.
    Yes, the machine was turned off when I connected the SATA cable.

    Well... This is embarrassing. :eek:
    I tried the drive in my hackintosh, and sure enough, the drive works with OS X.

    I then tried it again in the Mac Pro, and noticed the problem, the low profile right angle SATA cable connector has trouble going in all the way into the Mac Pro's extra SATA ports, obviously I didn't see that the first time I did it, since these ports are obscured by the fan assembly. With a little bit more force I got it to click all the way in and the drive is recognized when I booted up the Mac Pro.

    Now... The hard part. How do I fish the SATA cable to the upper optical drive cage, you know, where the IDE cables are going?
    I want to remove as little parts as possible.

    Its tricky but doable, I removed my IDE cable because I have no need for it and it takes up room. Fish it right through where the IDE cable goes.

    Got it in there... Maaan. I will never do this again. I did it without removing the fan assembly.
    The more time my hands spend inside this case the less I like it. PC cases aren't as nice looking, but they are hella more convenient to work in.
    Also I kept the IDE cable for the original DVD-RW drive, cause Mac Pro has two bays, so I figured to just keep both.
    Any way to change the order in which the keyboard Eject button ejects them?
    Pushing the Eject button by itself ejects the IDE drive, and pushing Option+Eject ejects the SATA drive. Can I reverse that?

    Uhh... Trouble. The machine doesn't go to sleep all the way. The fan on the 2600XT stays spinning when I send the machine into sleep. Before I installed the SATA drive, the machine would sleep entirely, including the video card.

    Well... I installed the GTX285 back into the machine, which I removed because the PCIE power cables were in the way while installing the SATA cable. With the GTX285 instead of 2600XT, the machine does got to sleep, but does so in a very strange manner. When I choose Sleep from the Apple menu, the screen goes black, but the mouse pointer remains. The machine stays on for another minute and then it finally shuts off into sleep. Oh well, at least it sleeps now.

    Nope, more trouble. The machine wakes up by itself and is in an endless drive power up and power down cycle. It's like it wants to go to sleep but then changes its mind halfway through the ordeal. Should I try updating the firmware on the SATA Blu-Ray drive?

    Did you make any progress with this?
    I ended up disconnecting the old superdrive, which improved reliability. Mine still has a 30 second to minute think before sleeping, but i never linked it to the BD burner.
