cd drive wont open/eject

ok so after recently installing ubuntu 10.10 i ran into a problem that needs to be resolved in a timely matter, so I turn to the community for some support. I'm having a issue with my dvd/blueray drive in my laptop. it is a acer aspire 5745 with a core i3 processor 500gb hard drive and 4gb ddr3 memory. So back to the problem my drive will not open for some reason. It is recognised in disk utility and in the bios and also I checked the plugs and everything inside the computer so that is defiantly not the problem because it will open when I boot into ms windows. I have also tried booting into safe mode which of course failed. If someone could point me into the right direction of solving this issue that would be amazing.
