My girlfriend recently dropped her laptop while the dvd tray was out which bent it and it won't open now. Is it possible to change the DVD-Drive on a Toshiba Satellite L305D-S5874. If so where I can purchase the part from so I don't have to pay the heinous repair costs. I have done a lot of work with desktop computers and some with laptops I just don't know where to locate this info.

Thanks to anyone who can help.

Yes. There are several available on eBay... Most of the drives are of equal quality and work well, but you may have to change the peripheral hardware to fit... If handy with small tools and logic, you can do it yourself... otherwise find a talented tech friend.
You should totally remove the optical drive and partially disassemble the Toshiba to make sure nothing else is damaged that will make repairs difficult.
Any impact damage great enough to bend parts in an optical drive, could have done other very severe damage.
