Q: I just found a long lost cd and was all excited. I went to put it in my computer but the hole wasn't big enough in the cd.
A: No, not an actual CD anyway. I have had some CD's which were a very tight fit on the spindle. It used to be that there were magneto-optical disks which were in a caddy, much like older CD drives which used a caddy. However, the spindle was different. In the magneto-optical disk the spindle was in the disk, not the drive. So, NO, I have never had a CD that did not bit, but I have had some which were very, very tight and barely fit without some measure of pressure to get the disk over the ball bearing detents which hold the CD center on the drive spindle.
