DVD/CD-RW Drive not reading DVD-R  

Hardware errors are most likely due to functionality failures
Look for any likely cause like if you haven't cleaned the drive yet, it might be dirty.
Else check the disc if its the faulty one, try other disc to read/write.
Hmmm, as of now that is what is best to check out.

Your drive is a combo drive: it can read dvd discs but it can only burn cdr's and cdrw's. Combo drives cannot read blank DVD-R's, because it is essentially a blank media that has yet to be formatted into a media type it can read. It's capability as far as DVD's are concerned is limited to reading DVD discs that already has data and/or media content in it. The only blank disc it can read and format would be blank CD-R's and blank CDRWs. If you want to burn your data on blank dvd's, you have to buy a DVDRW drive. What you have is a combo drive.

As previously mentioned here, if you have combo drive then you cant burn dvd'd but only cd's. try loading a cd rewritable to test if it works. if it does then you got a combo drive, and even try loading a dvd which already has data. if it fails to read than its hardware problem, try using lens cleaner and try again. as the cd/dvd is used many time its lens(laser) power decreases and hence cd /dvd device find difficult to read cd/dvd's or even fail to read..

Of course it will stop because your current drive will not support DVD burning. It can only support cd reading and burning plus DVD reading. You should buy a DVD RW drive, here are some good brands: Sony, Samsung, Asus, LG, Lite on. When you buy a DVD RW drive there is a third party software included for you to use in DVD burning. Hope this helps...

Is this the first time that you have experienced this? Or has the same thing happened with other CDs/DVDs? If the same thing is happening with different disks then it's likely that your DVD/CD-RW drive is slowly starting to fade out. However, there are things that you can try like cleaning the drive. Also, check device manager and have a look to see if you have any graphic symbols being displayed in relation to your drive. Good luck anyway. Andrew
