How do you find out if it ain't workin anymore? It still reads discs fine though I can't seem to get it to burn CDs properly anymore, and that's writing with data from a HD on a separate IDE channel. In Nero, the buffer goes erratic (usually it's 98-99% full, now it goes from 99-0-50%)
An aside question, what's the difference between Cable Select compared to hard setting it to Master or Slave?
