CD-Rs bake in the sun!
OK, I had a silver CD-R (Imation 80min if you care) with MP3s. I left it in the car too much in the sun (now I flip the jewel cases over). One edge of it turned a nice golden color like the older CD-Rs are.
It had 5 CDs on it.
I have randomly sampled the files in my audio player, and they all sound fine and are as happy as can be.
Checked the SFVs of 4 of the 5.
Even though my sampling sounded fine, EVERY SINGLE FILE had a CRC failure.
Keep yer CD-Rs in the shade!!!
