Problem: After resuming from Hibernate mode the DVD-ROM (Pioneer DVD-115 ) can not be accessed, attempts to use Explorer or browse My Computer will freeze the program and prevent shut-down.

Happens when you use Nvidia nForce 2 IDE (2.5) drivers. You will need to swap back to standard IDE controller in system/Devices.

Unfortunately the nVidia IDE drivers seemed to be the only ones which let me burn CDs properly.
