I tried to repair it, but after an hour of clearing bits out and putting the thing back together, testing, dismantling, rinse, lather, repeat I decided it wasn't worth the hassle. I still have it in case I magically run out of CD drives in some far distant future ... Antonio ------------------------------------------------------- One of the last projects we did at Philips US, was a study to see how fast we could spin the disk before it shattered. A friend of mine, a mechanical engineer, did the testing. He had a blast. It was like a mini version of Mythbusters. Even had the high speed television camera. To accelerate the process he would often nick or chip the edge of the inner hole. When they split - literally - it was right through the front door of the drive. He finally got his own lab so the rest of us would feel safer. But what a fun job he had! He loved his work. Billy
