A friend of mine has a 52 speed writer. As I am unfortunate enough to have the services of a humble 4 speed one I wonder if anyone can confirm that you have to be careful which CD's you use to burn at a full 52 speed.
He has given some CD's to friends which have crashed their computers. If he burns at a slower speed (like 16x) would this help.
The CD's have to be capable of being burnt at the higher speed. Most burners will detect the maximum speed capability of the CD and adjust the rate accordingly, but you can still find errors occurring, so it is best to set it to burn at a slower speed than maximum for a particular CD to ensure the best possible recording.
It is the CD disk itself that governs the write speed. For example a CD Disk with a maximum speed of 24x won't write at 52x. I always set my write speed one below the highest speed on the CD disk. The same applies to CD/RW disks, but I never write to a CD/RW faster than 4x
