Upgraded to OSX Lion 10.7.4 & optical drives are no longer recognized

HELP!!

I have a MacPro 1,1 with a 2 x 2.66GHz Dual-Core Intel Xeon and I just upgraded to OSX Lion 10.7.4. Upon upgrading my system stopped recognizing the two optical drives I had installed. Is there a patch or are there drivers that I can download to fix this? Has this happened to anyone else? I was prepared to lose access to some older software but not my optical drives!!!

When I do a "system report" through "About this mac" both of the drives are listed but they dont show up on my deskop. I have an Optiarc DVD RW AD-7170A and a TSSTcorp CDDVDW SH-S202N

Mac Pro, Mac OS X (10.7.4), 2 x 2.66 GHz Dual-Core Intel Xeon

Try SMC Reset

- Apple changed the page, has the 'new' layout rather than all the tech articles, troubleshooting, how to and FAQs.

Thanks! The OPtiarc DVD RW drive is being recognized now. The 2nd drive, the TSSTcorp is still not being recognized by the Finder but shows up in the "About This Mac" window.
