Strange behavior from optical drives

I have two optical drives installed in my computer but they do not work properly. During and before the computer posts the optical drives receive power, open when the button is pressed, and function as intended. Once the Avago Technologies MPT SAS3 BIOS shows up all of the hard disks and solid state drives are initialized but the optical drives aren't. From this point on the optical drives are completely unresponsive and don't open when the button is pressed. Neither of the optical drives show up in Windows. These optical drives worked just fine on a SAS2 RAID card in a different computer. Both computers have identical MPT SAS BIOS settings. Removable media support was turned off for the SAS2 machine but the optical drives were still fully functional. When I turn removable media support on for the SAS3 RAID card the optical drives still don't work! What do I do? Plugging the optical drives into the SATA ports is not an option.

Windows. You said it works in BIOS but not in windows, right?

The optical drives work before post but do not work in the SAS 3 BIOS or any operating system. The optical drives don't show up in the BIOS settings either.

Perhaps they're just not compatible with the SAS card you have to use (either on the drive side or the card side). That's really the only logical thing I can think of.

 

If you have any other optical drives you could try out on it, you might as well give that a go to see if they work or not.

Does your drive show up in bios if you just plug one in? I'm not too familiar working with whatever the SAS 3 bios is... could you provide a link to what you're working with? Optical drive brand as well as your mobo/bios?

The optical drives do not show up in the BIOS. I can't find a link that describes what SAS BIOS is and how it works but I have attached a picture of the SAS 2 BIOS on my old computer with working optical drives. The SAS 3 BIOS on my new computer looks the same except it is missing the optical drives. I can flash the BIOS but I am unsure how to do that. https://www.broadcom.com/support/knowledgebase/1211161501344/flashing-firmware-and-bios-on-lsi-sas-hbas

It could be a possibility but it is very unlikely. The optical drives worked just fine on the SAS 2 RAID card. I have tried three different optical drives and none of them worked.

Welcome to technology. Things that should work don't, and things that shouldn't work do. :P

The bios is only showing bootable devices? I think that is why the optical drives aren't showing possibly? What version of windows are you using? If you are using windows 7.. and these optical drives happen to be USB connected, make sure they aren't USB 3 because windows 7 doesn't support usb 3 on clean installs.

The optical drives are connected by SAS, not USB. I am using Windows 8.1.
