t633a dvd-RW keeps ejecting dvds when inserting

My alienware laptop m17x which iv'e had for about a year now, has had this weird problem where it ejects the dvds i insert into it immidiately. sometimes when i get frustrated i keep on trying and after tons of tries it actually works (it seem to work permanently til i manually eject it). Now i thought it was somekind of a sensor error or something and i dont use it often, so i didnt care, but then i read somewhere that if the dvd drive works perfectly fine when your in the BIOS it can be due to software related issues. Im using windows 7 with all the newest drivers avilable from dell's sites, and on my dvd drive (tsst t633a) i've also tried one earlier driver as well, but it doesnt seem to solve the issue. I also have two uknown devices listed in my device manager located at pci bus 1, device 7, function 2 and 3.

Does anyone know if i can get my dvd RW not to act this way?

 

i remember my brother had a similar problem when he was working on a laptop for a client, and this client reported that, fortunately, he found out the child stuck a million other CD's in there all at once, but i digress.

the way he fixed it was take it all out (the whole dvd drive) and clean it, though it may not fix the full problem, but it would be worth a shot.

 

After getting all my drivers and bios updated, the only way i thought i can deal with this problem was to buy a new dvd drive, which i did. But still, the same problem is accuring. I think i can safely say that the problem is not software related or the drive itself. Those anyone have opinions on this? maybe parts connecting to the drive or something?

 

Well what you've done including the drive swaps, and updates, leaves very little room to point your finger at anything you can fix yourself. Based on your troubleshooting we can rule out the optical drive and the BIOS. What's left to do is to restore to the factory image so we can rule out the possibility of wonky drivers and OS installs. If it still fails to work at that level, then we can point the finger at connectors and the motherboard, components that, unfortunately, most consumers won't have the time, knowledge, or tools to fix or repair themselves.

So really after restoring to the factory image and verifying that all your drivers are working, the only thing left to do is to have a technician try and diagnose the problem since it would likely be outside the scope of what we as consumers can attempt to fix ourselves.

Oh I forgot one thing, you can also try updating the firmware on the drives themselves; that's something you can do on your own.
