Check your computer drivers for that drive. It may be a driver error. It has happened to me before and I fixed it by reinstalling the drivers. It should be a software issue if you can still read CD disks.
- first try to clean the lens (use only a cleaner disk, no other stuff) - second try to read a cd or dvd written by this unit on LOWEST speed alowed, let's say 24x for cd and no more than 8x for dvd - if that does not solve the problem, a firmaware update for your drive will fix that
Are you sure it is a DVD writer, the specs for this laptop has a number of different drives one of which is a DVD/CD combi drive meaning it can read and write CD's but only read/plays DVD's.
Check the drive fascia if it says DVD-rom then it only reads them.
Try using a good wuality dvd cleaner. After that use a known good dvd to see if the drive will play it. If it does then try burning a dvd. Hopefully this will fix it. If not then there may be internal lens issues with the drive and it would be cheaper to replace than to fix. Hope this helps.
Let me explain some things for you to understand what happened with the dvd drive.
A laptop (or desktop) dvd writter drive is actually build around 2 separate optical systems each specialised to deal with either a cd or a dvd type of disk.
A cd has normally around 650mb - 700mb.
A dvd has normally around 4,3gb - 4,7 gb.
But both disks have the sime size. So the larger capacity disk, the dvd has higher data density as related to the disk surface. Therefore because these disks are being read using laser diodes, each diode must be tuned to a specific frequency for each type of disk. A cd is read/written by a 860 nm diode (infrared) and a dvd is read written by a 630 nm diode (red). These are separate optic subcomponents (by the way, a blue ray disk and reader is called blue ray because of the diode that is used to read them, it's on 437nm and it's emitting blue light).
If your drive will read only cd's and fail to read a dvd then it means that the coresponding optic block for dvd reading has failed. The cd optic system will continue to function as it's not linked to the dvd part.
In this situations there is little to do to save your drive so you should consider the replacement or assistance in a service center for your problem. I'm sorry as we aren't able to fix this without having to dissasemble things and use some service equipment.
How old is the notebook? There is 3 possibilities to get it fixed:
1. It might be the CD you're trying. Did you try another CD? or DVD to see if it does the same? -If yes you might have the read/write head dirty and all you have to do is buy a lens cleaner follow the instructions and clean the drive. This is worth a try. - If you are referring to CD's that you are BURNING with the same drive and the drive would not read it. Then most probably you did not get a brand of CD's / DVD's which are suitable for your drive. Check your drive's laptops manual to see the reccomended media.
2. Upon doing this check if you installed any software which might affect the drive. Such programs include. ASPI dirvers Daemon Tools copiers such as Nero and Alcohol 120% or others such as Clone CD. If so uninstall the offending program and reboot to see what happens. Sometimes even games might cause the problem.
3. Is the PC / Laptop old? As i did not have any details. And if it made any "funny noises" most probably its a hardware problem and it compromises reliability so if you tried all the above. You best bet is to check for a replacement drive. They do not cost much.
