My dvd writer can read and write DVDs but can't recognize any kind of CDs. When I insert a CD the disc just keep spinning and doesn't load. The writer is a LG GH22NP20. I have Windows 7 64 bits and Windows XP SP3 installed in my pc and both have the same problem.
check Data Cable. If writer is connected to middle socket of cable then,
connect it to end socket of data cable. or vise-versa.
