might be a power issue, try a different power supply and see wat it does.
normally the cd drives should open even tho it doesnt POST so check the Power Supply.
do this to transfere data:
1. pull out the HD that u want to transfere data and connect it to the second IDE (ribbon) cable slot from where the primary HD is sitting at
2. set the jumper to slave since its the secondary HD
3. go to the BIOS (hit Del, or F1 or watever it is ) and under the primary slave change it to AUTO instead of NONE
4. save and exit, load it up, then just drag watever u need to the other HD
do Vis-Versa if want to use start from the beginning
