I wanted an exploded diagram of an external HP dvd 940 drive, and of an external Plextor PX-610u drive, so that I could decide to try and repair it myself or not. I could not even find out how to take the outer case of the external HP drive (It seems to snap together, but I don't want to break it) apart. An internet search came up with lots of hits, but no real mechanical details. Many ads touted 'experts are on line' and 'quick answers to your technical questions' but of coarse for a fee. A repair manual search for the devices found nothing. Is there any internet site that is dedicated to suppling detailed mechanical information on electronic products?
