@^DVD-Roms wont Read Dual Layer^@

[Varchasve]

Greetings!

this my first post,hope wont be dissapointed,As i dont know where to post the Topic,so i used general section.

I got 2 Dvd roms,one is combo drive.other is Dvd writer.

All was Fine,Till My Both Drives Stopped Reading Dual Layer Discs Since One Month Back.
It is reading other CDs and Dvds(Single Layer) Fine.

10 Days Ago I formatted My PC,After Then I Saw That My Both Drives Reading Dual Layer Fine,Then No Problem,But After few days,First My Dvd writer stopped Reading Dual Layer,Then My Combo Drive.
I am Damn Confused Dunno what is the Problem???

Note-Reading is the Problem,Not Playing,Once It got Read,then it is Piece of Cake! (So Please Don tell me yr Player is Corrupted Or Clean Yr Lens)

Any Help Would Be Appreciated.

Regards.

Welcome Varchasve

And this affect is of course with both commercial and home brewed dl's ?

Could be drive dropping into pio mode

Control panel > system > hardware tab > device manager > ide ata/atapi controllers
Check channel associated with devices is set to dma .
Change if required , and reboot , recheck dma has stayed .

If not , check your system's bios setup .
Power off system , remove attached cable to affected drives , and reinsert firmly .

Try again .

----

If the effect is with home brew dl's only , nows the time to back them up asap .

You also get this affect if both drives are attached to same channel ... one sneezes , the other gets the cold , soon .

Agreed, BJS, Windows will do that to you.

If the discs are dirty and there are a lot of errors reading them, Windows will dumb things down to PIO mode in an attempt to "fix" things. In this case it only makes it worse.

Varchasve, turn your discs over and look at them in the light. If they have fingerprints or lots of scratches, then gently rinse them with tap water and a clean cotton cloth, wiping from the inside to the outside, NEVER in a circle around the disc.

Thnx For the Reply !

Sorry I didnt said I am not much into multimedia tech.,So i can say i am sort of Noob,I didnt got the Clear Meaning of what you said(Bold words)?

These R my settings:-











I never Touched These Settings,As i am not aware of the terms.so you can tell me what is wrong in them?
I dunno everything was Working Fine,I never faced this Kind of problem before.It is Very peculier it is reading all CDs and DVDs(Single Layer),But Dual Layer!
It feels Like If I Format My PC again It will Work Fine Again,But everytime i cant format for the sake of the drives....The Main Confusion is,It stops Reading Gradually.I never Altered Any of the Settings!
Please Be Specific!

Thnx In Advance!

That Is the First and Last Thing I tried Like Hell,The DVDs i am Talking About,Don need any Kind of Cleaning,They All R in A1 Condtion.

BTW My Drives R reading My Old Scratched Data and Movie DVDs and CDs,But Single Side Dual Layer Movies DVDs!

The screen cap shows PIO mode is "current transfer mode"

That is most likely your problem. You may have to remove both ide channels and let Windows reinstall them, then restart your computer and go back and make sure the settings stick.

The multimedia video device with the big yellow ! by it needs to be fixed, too. The "Unknown Device Indentifier" (get it here: http://www.freewarefiles.com/program_9_102_18028.html )is a small program that will tell you what the !device! is. You could also try removing it and let Windows reinstall it and maybe Windows will give you more info on what it is.

Go here and read: http://www.microsoft.com/whdc/device/storage/IDE-DMA.mspx
After 6 errors you must uninstall and reinstall to restore dma mode.

Go here and follow the instructions to do this: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/devmgr_....mspx?mfr=true

You need to get proper driver for that video card, the Conexant chip set was used in several makes including ADS. If it is a separate tv capture card and IF you DON'T need it for video out, you may as well disable it in the device manager until you find out what it is. After getting the make and model (look at it closely, it may say make/model), Google for the makers web site and get drivers from them.

The pictures show ide channels in dma mode, which is good. Highlight the dvd/cd rom drive and click the + to show what's connected. It looks like everything is fine. If you put dvds in the drive and then things crash, I would assume the drive has gone bad.

If one drive is bad and both drives are connected to the same ide channel, Windows will dumb down the ide channel, not the drive, so you will lose the proper use of both drives.

I've had dvd drives that would still read cds even after the dvd laser failed. If you want to make sure a drive is bad or not, take it out and put in it another computer and try to read a dvd there. Before you do that, get a data dvd (not a movie) from someone and see if that will read in your computer.
If your drive can't read a dvd udf rom, then it's time for a new drive.

You could also have a failing power supply. If the drives work in another computer, but not yours, leave the dvd writer out and get a usb 2.0 enclosure for optical drives (about $25) and put the writer in that. The enclosure will have it's own power supply.

I am Repeating again,It is Reading Data+Movies CDs and Data+Movie DVDs(Single layer 4.7gb) Fine,No Problem.
But Not Able to Read Dual Layer (7.86gb)

I even Tried With Single Drives Too (Removing the Other One),But No Help!

I think I can Try with another computer,But As i said Having Problem With Dual Layer!

Regards.

[Heywould3]

do you by chance have NERO loaded?
if so that may be the problem. over on cdfreaks forum there was a long thread about nero causing problems with drives not reading R/RW some would only read cds it was found to be the newer NERO i think the last version that worked that didnt cause the issue was 6.6.?.17 the last 2 numbers wer 17 im sure of.. dont remember the two sets between but it was 6 series.

if so just unloading didnt fix it. if you have access to another computer i would take the drive and placv ein the other computer and try to read the DL disk.. if it works then you found the issue.. you could remove NERO and go and delete all REG entries of NERO but that has its own issues the best bet would be a back up of data and a format reinstal.. i recomend this only is you test the drive in other computer first. and since you regard your self as a "noob" as well

[dcsos]

my friend has a similar problem when he first installs Windows , it works, thereafter , no dual layer media will read in his nec dual layer reader-writer (thereafter means after programs are installed)
He uses a system restore and the drive always works until he installs programs again, and so on...
(he hasn't identified the particular program taking away the drivers abilities yet, but how does XP allow this dammnit!)

I would buy a firewire card and put the drive in an external FIREWIRE enclosure and work around this WINDOWS BUG

[dnix71]

Two more suggestions and I'm out of here: The dvd burner didn't come with the computer, I assume. If you added the dvd burner yourself, did you replace the 40 pin ide cable with an 80 pin cable? There should have been one supplied with the drive.

UDMA 5 mode requires an 80 pin cable. http://www.pcguide.com/ref/hdd/if/ide/conf_Cable80.htm

Make sure the cable isn't pinched, cut, mashed or twisted hard, either.

If you put the drive in an external firewire or usb enclosure (you have both built-in to your computer), make sure you check the rear jumper settings. Inside a computer "cable-select" is probably how it would be set, but most externals require "master."

Last suggestion: to read a dual layer movie the internal region setting must match the disc for some dvd drives. Go here to get the tool to check your drive settings and compare them to the disc you want to play : https://www.videohelp.com/tools/Drive_Region_Info


Nero has its own ASPI layer, that's why it can cause playback problems. Windows doesn't like having to sets of memory resident drivers loaded for the same device.
