DVD problem 1

[omegabetax]

I've just installed a new LG DVD device on my computer. It was bought withoutany cable or documentation (cheaper). After restart and enter in XP no DVD device apear in My computer. In Device Manager at DVD/CD-ROM drives apears OC3029Q UAP423H SCSI CdRom Device four times.
The difference is the Target ID 0-4.
Practically I cannot use the new device. Can someone help me ?

Thanks

First of all, we'll need to know how your drives/devices are configured. Tell us what's on your primary and secondary IDE channels, and which devices are set to master/slave.

Here's a general rule about IDE configurations:

- Master and slave combinations can often times work better than CL (cable select). The Master device should be located at the end of the IDE cable, and the slave should be attached to the middle connector (or left empty).

I have a CD-ROM, a new DVD-ROM and a HDD and 2 IDE slots on the motherboard. With cable select or master the DVD-ROM on connected on the free slot didn't work.
The problem is solved. I have now HDD-master and CD-ROM-slave on slot1 and DVD-ROM-slave on the second slot.

HDD is o the middle and CD-ROMat the end and work fine. Why they must be connected viceversa ?

Thanks

Sometimes, it makes no difference where on the IDE cable you place the master and slave. If everything seems OK, then just leave them there. If in the future you notice any problems or slowdowns with the CD-ROM drive, try switching their positions on the cable.

Now you mention that your DVD-ROM works fine as "slave" when by itself on the secondary IDE channel. That's strange, especially since it didn't work as master. Is it connected to the middle or end of the cable? Are you sure that the jumper is set to slave?

Actually being set as master the computer stop and wait for booting from CD. Because I have 2 masters DVD-ROM is recognized the first.

Sorry, but that doesn't make sense to me. You have 2 IDE channels. Each one can have only one master and one slave.

Maybe you have the DVD-ROM on the IDE0 channel (primary) all by itself. That could be your problem. You should have the hard drive and the CD-ROM on the primary, then put the DVD-ROM as master on the secondary (IDE1).


Since everything is fine now, I guess we won't worry about it too much...

Yes that's right. I've already write some DVDs. A thing isn't clear for me: what the diference between 16x and 4x DVDs.
Both use the same technology isn't it ? 16x means more information that can be read/write/second, so from where comes the difference ?

 

[TheDigitalDoctor]

Basically it's all to do with dye sensitivity and reaction speed.

The faster the dye reacts and the less power from the laser it requires to change state then the faster the data can be written.

Sometimes it helps to get a clean burn by reducing the write speed from the maximum. You will never get a clean burn if you write faster than the media can handle.

The new DVD is LG OC3029Q UAP423H SCSI CdRom. Why the SCSI appears in the name ? DVD devices used on SCSI interfaces can run on normal IDE interface ?

 

[cdogg]

omega,
That's just the way the manufacturer (LG) configured the drive to show in Device Manager. SCSI isn't just an interface. There are many protocols associated with SCSI, and ATA (IDE) "borrows" some of those protocols. It's just a name - I wouldn't be worried about it.

As for the 4x and 16x DVD's...

This is the "speed" rating of the disc. Most 4x discs out there are old and came out when DVD burners were still fairly new. They were never tested for speeds higher than 4x (because it wasn't available at the time it came out).

Some 4x and 6x discs from quality brands can be forced to burn at faster speeds than their rating, but there's no guarantee it will be successful. It would be best for you just to buy 16x from now on if "speed" is your concern.


DigitalDoctor,
If you've read any of this thread, you likely would have noticed that omega's first language does not appear to be English. Your response can sound pretty complex to even native English speakers.

OK. Thanks to all.
