CD-RW drive intermittently will not eject - ThinkCentre A30, A50, A50p, M50, M50e, S50 / ThinkPad R51, R52, T42, T42p, X40


After inserting a program CD or DVD, the drive will not eject. The cause of this problem is a conflict between IMAPI and IBM DLA.

How to recreate the problem

The following procedure will cause an Autorun program CD or DVD not to be ejectable. The frequency of failure is approximately 1 in 10 reboots:

  1. Power on the system.
  2. When you reach the Window XP desktop, insert Autorun CD media.
  3. Cancel installation menu, then press eject button or select S/W eject on drive property. The disc will not eject.
