Windows 7 64 bit doesn't recognise some dvd's

November 14, 2010 at 07:48:53
Specs: Windows 7 64 bit, amd phenom II / 8gb ram

first I have:
windows 7 64 bit on my machine. I have had it installed for over a year. Recently I went to reinstall a game and the dvd looks like it is trying to acces the dvd but windows does nothing. Now its not every dvd just certain ones. I can also take the dvd thats not recognised to another computer running windows 7 64 bit and it loads. Now one of the dvd's that won't play is from a game thats already installed. This is really puzzling me. I've tried shutting off my virus suite no joy. Any help would be appreciated.

There is nothing wrong with your computer. You just need to adjust some settings in Autoplay.

Go to Control Panel> Autoplay and set according to your needs.

If a disk doesn't open you can always use Windows explorer to start an action.

I personally do not like autoplay and usually have my optical drive set to do nothing for most types of disks.

well I've been there and no joy. Everything is set to ask. Now i've noticed that when I have my computer up and I click on my E:\ drive rather then popping up with " please insert a cd into drive E:\" and opening the dvd drive bay it pops up with "application not found" . Now I have two dvd drives drive F:\ pops up with the normal pop up when clicked if a dvd is in the bay or not. I've checked for driver updates . I've removed the drives and reinstalled them. I haven't installed any new software. This really peculiar to just all of a sudden quit working for certian dvd's

Make sure the disk is clean and free of major scratches. Makes/models vary regarding their ability to read a scratched disk - e.g. LG drives are poor for that - Plextor drives are very good at that. .

Your laser lens may be "dirty".

If this is a laptop, or a netbook computer that has a built in optical drive, eject the drive's tray, and with no disk on it, clean the obvious laser lens with a tissue or a soft cloth.

If you're using an external DVD drive, if it's a smaller "portable" drive that has no external power adapter, do the same thing.

If this is a desktop computer (or for any optical drive), use a laser lens cleaning CD in the drive. If you don't have one, most places that sell CDs and DVDs have them, or even some "dollar" stores have them for a buck or two.

If you're using an external DVD drive, if it's larger drive that has an external power adapter, use a laser lens cleaning CD in the drive.
.......

Some burning or optical disk related software installs a "virtual" optical drive - the drive letter of it is usually of no use except for with the software (you have more optical drives in the operating system than you have physical optical drives).

E.g.
It's created in more recent Nero versions that use a module called Imagedrive. E.g. Search for Imagedrive in this:
http://www.lib.utexas.edu/help/libs...
If you don't think you'll use Imagedrive, you may be able to un-install it in Add/Remove Programs if it's listed separately, and/or by changing something in Nero's configuration or Properties, and that will get rid of the virtual DVD drive and it's driver listing in Device Manager.

I'm sorry I messed up my explanation. I have two lite-on dvdrw's installed on my computer. I think my last post confused things by sounding like I have two F;\ drives I don't. I should of put a period at the end of the sentence. Now I believe the problem is the dvd players or win7 not sure which, is seeing cd's but not dvd's. The dvd player will load software "cd's" like the ones you get with your sound card or video card, but not game software which I believe are probably on dvd's. I've tried system restore but no help there. It may be my motherboards sata ports. I'm grasping at strings here.

Combination CD/DVD drives have two separate lasers that work at different wavelengths. These lasers are mass produced and considered disposable hardware. Frequently one laser or the other will fail. Sometimes, as explained above the lens on the laser can become dirty (sooty), and result in diminished power.

The power of each laser can be modulated. to simplify the explanation high power is used to burn and lower power to read. The type of disk, rotational speed, etc. come into play when the drive is calibrating the necessary power.

Long and short is that if the drive works partially then the issue is either a dirty lens or a failed/failing laser. Optical drives are cheap. Look at newegg.com for a replacement if necessary. Be sure to buy the correct type of data connection (ATA/IDE or SATA).

Despite the way your second post was worded, we know you don't have two optical drives assigned the same drive letter - that's not possible.

If cleaning the laser lenses doesn't help, if all the disks are original disks, then at least one DVD specific laser and/or it's associated circuitry is malfunctioning. It's extremely unlikely that would malfunction on two drives at the same time.

If any of the disks are burned copies, CD-R and DVD-R disks should read fine in nearly all drives that can read them, but other types of disks made in a different make and model of burner drive may not read properly in your drives. Also, I know of a case where a CD-RW disk initially worked fine, but later on (a couple of years) the same disk, same data (it was only burned to once) would not read reliably in the same drives it worked fine in intially.

Well I tried the dvd cleaning disk. I've blown them out with compressed air and no joy. I just can"t believe that they would both go at the same time. With the same problem. But like someone back in this thread said they're cheap so buy two. Thanks for all the help everyone.

So, I am not really clear here. Are you stating the drives will or will not play some DVD media? If so, what kind.

Are the optical drives listed in Device manager by their model numbers?

The drives won't play any DVD media commercial or otherwise. Now i'm assuming they will play cd's because I just installed 2 video cards in crossfire mode and it worked to install the drivers disk for them and I presume that that disk is cd media not dvd. I've tried commercial movie dvd's I've tried game disks like Far cry2 , Crysis, Tom Clancys Splinter cell no go. I tried software disks, all driver disks that came with the hardware on my computer and they work. They wouldn't load a win7 disk. I just burned a bunch of music cd's a couple of weeks ago. The drives are just over a year old and its not like I was constantly using them to burn disks or play movie and game disks. I'm listening to a music cd as I type but put any type of dvd in and it won't recognise it. The player will spin the lights will go on ,the curser will change to a spinning disk for a second then the player light will go out and nothing. In my computer both players show up, in device manager they are listed by name. In my computer click on them and they come up with please insert a disk and open the tray to the player, even though theres a disk in the player. I guess its the era of dispose-a-player.

Then the issue may be either ASPI layer drivers, or upper & lower filters.

Did you recently install or uninstall any burning programs, scanners, AIW printers, etc?

Did the drives ever work for DVD media with the current installation of Windows 7 64 bit?

"I can also take the dvd thats not recognised to another computer running windows 7 64 bit and it loads"

That statement early on is what has confused us. You indicated that some DVDs worked. Now you state none work. Much different causes.

The confusion on my part was the player loaded a ROTK game disk and I assumed it was dvd but its in cd format. I have also taken them to another computer running Windows 7 64 bit and they play no problem. Haven't installed any new burning programs. I have just recently downloaded and installed software for steam and some games from there. But nothing else.

I haven't seen this issue with Windows 7 but it was common with XP.

Are the drives internal SATA type connection or something else?

I had an issue somewhat like this a good while ago. I use a dvd recorder to record shows from television. I burn these shows to a dvd+rw and transfer to the computer to edit. First the drive in the computer would no longer read the dvd burned in the recorder but would read and write to a blank dvd+rw. I figured it was because the discs I was using had been used many times and a I bought new discs. The new ones would not be seen by either my recorder or my drive in my computer. I tried almost every brand on the market locally and several different brands from newegg. None would work. Tried replacing the dvd drive in the recorder but I am assuming some propriatory issue prevented that from working. End of story I bought new recorder and dvd drive for computer and all is good. Still have the old drive in the computer. After taking it apart and cleaning the lenses with alcohol and making an adjustment it will read cd's and commercial dvd's and dvd+r that I have burned. It will not read any but two of the oldest dvd+rw's. So I am at a loss and just decided from that point that I must have worn them out.

Likely

"Did the drives ever work for DVD media with the current installation of Windows 7 64 bit?"
Yes all the game disks had worked with windows 7 64 bit before. None of these aare burned disks all are commercial disks. Yes both drives are sata. I've got two new drives coming now so we'll see how they go.

Windows has a problem with 2 identical optical drives so I recommend you run two different brands. I currently have 2 DVD burners and 1 CD burner all in a full tower with no issues. All are different brands and models though.

Normally I would tell you to start your own thread here. In this case I will tell you what is wrong. Your laser that is used to read and write CD media is either dead, dying or the lens is dirty. Try a lens cleaning kit. If that doesn't solve the problem then replace the drive. I consider optical drives disposable hardware.

If you are in the USA or Canada look at newegg.com for good prices and service.
