My laptop doesnt read disks

Insert a disk. Wait for the disk-spinning to stop.
Open "My Computer".
Double-click the icon for the CD/DVD drive, to see if Windows can read anything from the disk.

Put a DVD disk into the drive.
Open "My Computer".
Right-mouse click on the icon for the CD/DVD drive.
Click "Explore".
If a window opens, then your hardware can read the DVD media.
If not, then you need to replace the CD/DVD drive.

Then, you need software, such as the _free_ 'VLC' software,
downloadable from the Internet, to play DVD-videos on your computer.

This simply indicates that your DVD drive lense is faulty/dirty, try using a cleaner to clean the lense, if it doesnt solve the problem, then i think you need to look for a change for it.

Hello my friend, try to clean your DVD Disk drive . You can use Liquid CD Cleaner to ensure the cleaning of your Disk Drive is properly clean. If you don't have a CD/DVD Disk Cleaner kindly check it in the nearest Computer or Video Shop in your place in order to buy and clean your Disk Drive.

I have this video camera. It seemed like a good deal at $200 at Christmas time. It is suppose to be able to record on DVD-R, +R disks. (re-writable and write disks) I have had issues with not being able to finalize the disk. I found you needed to keep at least 5 minutes on the disk to finalize it. It will not play in any DVD player or a Computer till it is finalized. The info stored on the disk is in RAW form. Finalizing it will create a "lead in" and "lead out" and a menu for your computer and/or DVD player to understand. A large part of whether it will play or not, is what is your DVD Player or DVD Drive on you computer capable of? DVD Players usually will play anything that has been finalized, same with your DVD drive on your computer. BUT! Yep there's a but, sorry. DVD players and DVD Drives sometimes can only read one type of disk. Either a DVD-R or DVD+R, some may not be able to read a re-writable disk too. Look through your manuals on your Laptop and your DVD Player(s) and try to match the correct media (i.e. DVD-R or DVD+R Write or Re-Writable) I found that between my PC and my DVD Player, that DVD+R would work without a hitch for both electonics. Download that software that Samsung gave you in with the video camera. It may end up loading the driver software to help you're computer to recognize the video DVD you are trying to play. Oh, and make sure you really do have a DVD player/burner drive installed. I went to play a movie on my wife's Laptop and found it came with a CD drive and no DVD drive. That's not what I ordered and I was about a year to late to complain to the company. :( Hope that helps.

ON a computer than can read the disk and has CD/DVD burning software installed on it, check the status of the media sessions. If this was writtien as a multi-session disk and the session has not been closed, many older drives will have difficulty reading it.

The disk should actually show up in the My Computer window as a removable drive. Right click on the icon, and select explore.

You should be in the file now.

It sounds like Vista has recognized the device as a CD-ROM drive, but NOT as a DVD-ROM drive, and the disk you have inserted is a DVD.

Try getting an updated driver and possibly a new firmware from http://www.lge.com/support/software.jsp

If you have both the DVD and CD drives connected to the same ribbon cable you want one set to Master and the other to Slave, or both set to CS (cable select). Good luck.
