About Cd writer and Dvd drive

[Robert30]

Hi Guys,

I am having cd drive and dvd drive to my computer.
When i connected cd drive and dvd drive to my computer.
It only recognising dvd and not cd player.
And how can i create another drive to the cd driver to recognise the drive.
Can any one help me in solving my pc problem?


Thanks in advance.

get a splitter from any shop that sells computer cables .like Radio Shack

There is no such object as a splitter !!! If the system only notes a DVD player and not CD player (or virsa versa), it just means you have the jumpers wrong on the back on the DVD/CD player.

Look at the rear of both drives, and you should see this..

--------------------------------------------------------------
|....................| |...|
|__| |___| |....................| |...| |oooo|
--------------------------------------------------------------
CD Audio 40Pin IDE | Power
Digital 3pins Connector | Connection
2pins
These are the jumpers

The jumpers usually look like this...

|. . .| (Slightly larger obviously)
|. . .|
|. . .|
Master(M) Slave(S) Cable Select(CS)

You need to make sure the CD is on Master, and the DVD is on slave, otherwise the two will create what is called an IRQ conflict.

Reboot when you've finished, and make sure the BIOS (usually delete key while cold booting) lists the two drives on seperate channels.

Hope the rather stupid looking diagrams help you. Any further details, please contact me.

Regards,

Paul.

NOTE: IT LOOKS AS IF THIS FORUM REMOVES UNWANTED SPACES, WHICH MAKES IT IMPOSSIBLE TO DRAW A DIAGRAM FOR YOU. IF YOU WOULD LIKE TO GIVE ME A CALL, I WILL GLADLY TALK YOU THROUGH IT.

Yes there is a power cable splitter. He editted his post though to a completely different question.

VisionIT is correct, except it doesn't make an IRQ conflict, it's more a cabling conflict.

I apologise... i didn't realise he editted his question. lol

You're quite right, there is a power splitter available, although i wouldn't recommend it. The PSU is built to give an equal voltage down each cable, so splitting the power cables for fans is OK, but secondary hard drives is not advisable. If you need more power cables, i'de upgrade your PSU to 400Watt.

I thought you meant IDE splitters BTW, again... sorry. The maximum 40pin IDE's available through one cable is 2 (3 including the motherboard riser)

Oh... JoshT, remember the old ISA SCSI expansion cards with manual IRQ and DMA settings... CD-Rom's/DVD's/CD-Rw's all use the same old technology. The IRQ of the primary and secondary channels are controlled by the device connected (NOT IN RAID or SATA 150), that's why firmware upgrades are released for CD-Rw's and DVD's, as the architecture of some drives conflict with some mainboard drivers. If you've ever used those cheap crap ECS boards, you'll know what i mean. lol

Anyway... the offer still stands. If you are still having trouble, give me a bell. The mobile number is probably the best number at the mo, as were moving premises (finally!)

All the best, regards,

Yes, I know that ATAPI is a poor man's SCSI, but I have never seen a IDE/ATAPI device itself use an IRQ. The controller will use one, but I'd assume the master and slave and the channell would both use the same IRQ as their parent controller was assigned. Unless Windows System Information has been lying to me. Also, I was under the impression that CD-RW drive firmware upgrades were to make them compatible with more brands/dyes of CD-R/CD-RW media.

Firstly....

An IRQ is made up of several complex items, including I/O (Input & Output Ranges)

IRQ's are built up of hex addresses, of which I/O is one of them. Now... when a cd-rom and DVD are installed properly, they are on the same IRQ (agreed), although they are on a different I/O range. If a cd-rom and DVD are NOT installed correctly, they create an IRQ conflict. IE, the IRQ remains the same, but the IO ranges conflict. Therfore, when you disable a channel, only a certain range is disabled. If it disabled the IRQ, both the primary and secondary channels would be rendered useless. VIA boards usually come with the option on switching off a channel for diagnostics purposes.

Secondly....

Take a DETAILED look at Plextor's site, and tell me what you see regarding firmware upgrades... hmm...

This is in black&white on Plextor's website... so take a look.

PlexWriter 16/10/40A Firmware Upgrade 1.05

1. Fixed a bug where the drive could not mount a CD-RW disc formatted by InCD v3.16.
2. Fixed a bug where the drive may hang when scanning a mixed mode CD with CD Creator 5.1.1.102.
3. Fixed a bug where an Auto-Run disc does not run on Windows XP system if the disc is the first one inserted after power on.
4. Fixed a bug where the system would freeze when coming out of stand-by mode on Windows 2000.
5. Added support for Orange Book Part 2 Volume 2 version 1.1

Can you see any mention of media in that little description.... hmm, No!

Windows system info has not been lying to you, because you haven't looked close enough.

Can i suggest some sort of MCSE in Administering Windows XX?

Paul.

I apologise... i didn't realise he editted his question. lol

heh,..its ok . It happens alot here where people ask a question, I give an answer based on what they asked that seemed like the proper answer, then they edit their question and I look like a complete idiot for my response.
