Hi
Its normally quite easy to remove the dvd drive just a couple of screws underneath
But if you havent got the manual for your laptop then you could go to
www.toshiba.com then to support/downloads type in your make model and look for the manual and download it
you will need adobe reader installed to read it and save the download to your desktop or pendive for future and easy use
this should tell you how to do it
Or if you google how to remove dvd drive or look on youtube you will probably find a video on how to remove it
