My G4 will not read/import files from certain burned cds. It makes a loud, whirling sound when I put them in and I have to force quit all programs. This doesn't happen with regular CDs. Are the cds burned at too high/too low a speed? Is this going to wreck my computer? Can I change the speed that I am reading them at? I'm at the end of my rope I don't know what to do. Running OSX, 867 mhz, 512 mb, etc. Please help. Feel Free to email: MM62@aol.com Thank you so much!
