Re: my drive cannot detect dvd disc but can read and...
Check device manager in control panel under
hardware to see if you have a problem with anything (a big yellow
check). The most likely casue is that your DVD burning software (not the microsoft programs) did not install properly. Find out the exact info about yours by downloading a freeware program called Belarc Advisor (Googe it),
Oddly enough, you don't need drivers for the CD/DVD drives. They
aren't even recognized unless you have a non-microsoft burning
program. After you find out what burning
software you have-- you have to seek a download at the computer manufacturer's
website, if it came with the computer, as it may be a special program not related to the burning
software if you purchased from the software manufacturer---go to their
website for downloads or upgrades,and that should get you going.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

First reinstall the DVD driver to see if the DVD drive works. If not then - Try removing the DVD drive and inserting it back to make sure it properly connected then boot up the laptop and go into the BIOS and see it the DVD drive is detected, if the DVD drive is not detected then the DVD drive is faulty and needs to be replaced.
Try to open control panel then click add hardware. If you have entered the dialogue box, answer whatever is asked according to what you're searching.

HI, THERE ARE CD PLAYER THAT REQUIRED ONLY CD+R, DVD+R. IF LOAD CD-R NO GUARANTY THAT WILL WORK. i HAVE A PC THAT HAS DVD/CD ROM DRIVE IT DOES NOT WORK TO ANY DVD /CD -R. I HOPE THIS WILL ANSWER YOUR PROBLEM I BOUGHT LOT OF BLANK DVD-R WHICH I CAN'T EVEN USE. TILL BOUGHT A DVD/CD WRITE CAN READ THE + AND -.
These discs that are written on other systems, were they finalized or are they multi-sessions discs that have been left open? Some drives have difficulty dealing with multi-session discs created by other drives. By telling it it is OK to format the CD, it is writing a new TOC (Table of Contents) that is blank since it did not see anything on the disc previously (so it didn't know there was anything to carry over from previous sessions). Now all other drives that try to read this disc are now reading an empty TOC and figure it is a blank CD.
You can try writing a disc on another computer and making sure it finalizes it, then try reading it with your laptop. You can also try to burn data to a CD on your laptop making sure the disc is finalized and try to read it on another computer to verify these suspicions.
what do you mean not recognized? not detecting the drive or not reading? if not recognized by windows you can check the driver for drives in the windows if not reading it is the lens problem..if the lens problem, the solution only is to replace the lens or to replace the whole drive
CD drives work by reflecting a laser to a sensor, where the existance or absence of a reflected signal corresponds to a 1 or a 0 in the binary code.
Prefessional "pressed" CD have a much greater level of "contrast" between 1 and 0, while CD-Rs have a lower contrast and CD-RWs lower still. This is why many older CD players that were not designed to read CD-Rs will either not read writable disks, or will read only CD-Rs and not CD-RWs.
Since you are able to read "high contrast" CDs but not lower contrast CD-Rs, it sounds as though your drive is getting a poorer signal than it did when it was new. This could be:
The laser is old and fading out.
The system is mis-aligned.
The lens is dirty and the signal is not all passing through to be detected.
You can't do much about the first two, other than buying a new drive (you could get a replacement internal one, or an external USB CD drive). However, before you do that, try very carefully cleaning the lens. A laptop CD drive usually has a try with the lens mounting in it which spits out with the CD, so you could either clean it manually with a little rubbing alcohol (isoproyl alcohol), or meths on a cotton-wool bud, or preferably get a lens-cleaning CD and run that in the drive.
I wanna ask one thing, does your compter show CD/DVD drive in My Computer menu? If yes, then its hardware of DVD/CD drive problem, not a virus. Clean the lens of drive with fine cotton swab, hope it works/ reads.
