Click start control panel administration tools computer management device manager scroll down cd-dvd rom drives you might see a yellow question /exclamation mark ? ! or a red X right click to update driver

You might have to physically unplug the leads for this cd/dvd restart your computer then plug them back this should activate the found new hardware wizard

If this does not fix the problem it might be a registry problem
"you only need to do the following"
if you cant see your disk drive in windows explorer


Close all open programs

Click on Start, Run, and type regedit and press Enter
Click on the plus signs (+) next to the following folders

HKEY_LOCAL_MACHINE

SYSTEM

CurrentControlSet

Control

Class

{4D36E965-E325-11CE-BFC1-08002BE10318}

This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

Upper Filters

Lower Filters

Upper Filters.bak

Lower Filters.bak

If any of the above keys shown in step 4 are listed, right-click on them and choose Delete

After deleting the keys, close the registry editor
Reboot your computer

Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.


Hope this helps.

My DVD/CD+RW will not recognize CD or DVD (Lite-On DVDRW SHW-H65)


It sound like your DVD/CD+RW has a problem with the read/write head. So u can use some cleaning liquid to clean the head. After cleaning hope it will work on CD. Most of the time DVD are not played or read properly when you eject the disk while in use.

OS is Windows XP Professional CD drive will not reconize a DVD+R for recording data. The drive is a HL-D-ST CDRW/DVD GCC4244.


A CDRW/DVD is a CD-burner and DVD-ROM combined unit. It is not meant to record DVDs only CDs.

It will not recognise a blank DVD as it is unable to read any file system.

No sound output and will not reconize Dvd's, but will reconize cd's


I'll take that as a no,

In fact the default for most types of media is media player but it doesn't include all of the relevant codex's you require for every type of media by default.

Most manufacturers include this software with their computers/DVDROM's but not always.

The reason I assume it is your codex not being installed is simple, you can play CD's, that means the drive works, media player works, sound card works and speakers work. The only common problem that would cause this is a missing or corrupted codex.

try something for me and let me know if it solves the problem.

Install VLC player http://www.videolan.org/vlc/download-windows.html

Then try to play the DVD using VLC player. If it asks to update itself, let it.

Comment back here once you have tried and let me know how you make out.

Latitude C840 wont reconize optical drive in BIOS


When you get no disk error, that is usually because of a problem with the optical laser lens that is dirty, faulty or opaque, and will start operating on certain disks better than others.

In that case you will hear disk spinning, whirring and clicking, but the TOC (table of content track at start of CD/DVD will not be read, therefore the error.

Whe this problem is starting you may be able to read only CD, DVD or Blue ray, or for example only DVD-R and not +R , or only to read and not to write and so on. After more prolonged usage , often the unit goes losing the rest of functions, and ends up not reading anything at all.

If instead there is no noise, and disk does not spin at all , then there is a faulty motor, or the motor micro-switch is bad. This situation is far less common than the lens problem.

Try first using a CD/DVD or Blue ray lens cleaner disk to clean the lens. If that does not work you will need to disassemble the drive , and clean lens directly with q tips and isopropyl alcohol, or to replace the the whole drive unit.

DVD and CD devices not reconized.


Did you add or remove any CD/DVD burning software recently? If so then there may be is a registry edit you need to perform.

More simply, though, if the problem is recent you may try to do a System Restore back to the time before you had the problem.

Won't read dvd


i'd say that this is caused by whatever program was used to do the DVD backup..you'll need same program, to most likely unencrypt that data, no?
