Mac Pro CD/DVD Drive not Reading Data discs

Hello,

I'm trying to install some drivers on to the computer so I can use an Icon Q Pro X interface.
I put the CD in to the drive and after a few times of trying to read it, it spits it out. I've tried a DVD installation disc and the same thing happens. When I put an audio CD in, it reads the disc fine.

Icon have not put the OSX drivers on their site yet so the CD is the only way of getting them at the moment.
I Have recently updated the OS to El Captain from 10.8 and I did a Time Machine before and after the update.

I saw on some forums that it could be the permissions but El Captian has kindly got rid of that button.
Any ideas on what to do next?

Here is my setup if it helps:

Mac Pro Early 2008
El Captain 10.11.6
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 3 GHz
Number of Processors: 2
Total Number of Cores: 8
L2 Cache (per Processor): 12 MB
Memory: 12 GB
Bus Speed: 1.6 GHz
Boot ROM Version: MP31.006C.B05
SMC Version (system): 1.25f4
Hardware UUID: 2D7FCCC9-DF25-5764-AC05-D0D5FBBF5BAD

Thanks!

Hello Tobias. Since the drive seems to read some disks & not others. Here are a couple things to try if you haven't already:

- Clean the drive with some compressed air (canned air).
- Clean the disks that are unreadable (maybe there is foreign matter on them, fingerprints, smudges, etc.).

HTH,

Hi Nick,

Thanks for the quick reply.

The CDs and DVDs I've tried are brand new or spotless so not the issue.
It reads the audio CDs on the first spin or two. It seems to consistent for it to be dust imo

Your Mac Pro is approaching its ninth or tenth birthday. Maybe the optical drive is shot. Easy job to replace and Pioneer DVD-RW are easy to fit and pretty cheap. They are also native to Macs.

Nick also advised you to clean the drive with compressed air. Did you do that?

all original components too, which is not bad going.

Today I have had some success! Tried a few other data DVDs and CDs and they worked so I tried the original CD in question and after a couple of goes, it loaded

chscag, I will be giving it a clean next weekend.

Thanks to all of you for your help on this problem

Congrats Tobias.
