Macbook pro will only read audio cds

Question

My MacBook Pro2,1 17" will no longer read anything other than Audio CDs in its drive. Any other format and it says the CD is empty. It never used to do this. I wonder if upgrading to Mac OS 10.7 (Lion - which is as far as this hardware will go) will fix this problem, or has the firmware gone awry? (What a great pity they don't make 17" laptops anymore.)

Answer 1

This is not related to my CD problems, for which you have been very helpful, but you may be interested as you seem to be au fait with the older MacBook Pros.
Some time ago, I purchased a new power supply for my Mac which came with a MAGSAFE 1 L-Tip magnetic adapter. The original had been a MAGSAFE 1 T-Tip but it had worn out and the coaxial screen was looking very exposed. All went well until, inevitably, the laptop was dropped. The L-Tip stayed in place and because of its sausage shape, dented the side of the casing. It [the L-Tip] would no longer make contact (because of its long body) so I reverted, very gingerly [an English expression?] to the original T-Tip which still worked. I then ordered what I thought was a new T-Tip supply but when it arrived, turns out there is now a MAGSAFE 2 T-Tip (which of course would not work). Maybe they have abandoned the L-Tip because it is self destructive. I have now finally returned the MAGSAFE 2 and await a MAGSAFE 1 T-Tip. A cautionary tale for those looking for a new power supply.
