Re: Mounting CDs

I would try them on a different device to see if they still work.  The 
coatings in some discs wear down over time, sometimes just after a few 
years.  It could also be that your drive is bad or dirty.  You could try 
cleaning it, usually just touching the lens with a q-tip(don't rub it or 
anything) will do the trick.  I should also mention that from what I 
understand, LG drives are some of the worst.  Mine will burn discs just 
fine, but is starting to have issues reading DVD's.  Its actually 
managed to lock up my whole system trying to play a DVD.  It may simply 
be time to upgrade.
