It just dawned on me. The only thing i brought out of the old system as part of the upgrade is the 16x dvd-rom.
In the ASUS bios settings, the new pioneer has a marker for PIO (auto, 0-4) and DMA (DMA, MDMA, UDMA) whereas the old dvd-rom (set to slave) is either auto or PIO.
I tried setting the Secondary IDE for IDE-0 "DMA if availible" and IDE-1 (dvd-rom) to "PIO only" to see if there's some sort of conflict with the old drive.
Nope... :(
Is there any possible way that a setting on the old 16x dvd-rom (slave) could be causing the (master) pioneer (and former sony) to only work in "PIO Only"?

Oh yes, if they are on the same IDE..............
Disconnect the dvdrom and see what happens......
...............PIO is no go, DMA all the way...............

Okay...Somebody want to explain exactly how a slave DVD-rom can cripple its master optical drive to being in PIO mode only?
I disconnected the power molex and ide cable from the dvd-rom and the new pionner runs in UDMA mode 4 perfectly.
Odds are this was also causing the error with the Sony dvd-+RW.
And this was a darn good dvd-rom too. Ripping speeds usually exceeded 6X (its a 16x but i doubt i'll ever see ripping speeds that high).
Hey Nephilim, got a suggestion for a fast-ripping dvd-rom?

Oh yes I do :)
The Lite-On 166S or 167T is, in my opinion, the best little DVD ROM out there. I've used mine for two years now and the thing still blazes through everything I've stuffed in it (except that pancake but that's another story). They can be picked up for around $30.
Here's an exapmle:

Nephilim, new Lite-on installed and both the Pioneer and Lite-on are working in pristine UDMA mode.
I'm still puzzled how the dvd-rom could cause the master to work only in PIO mode but ah well.
Time to get to work!
Thanks people!

I'm puzzled too, probobly just a bad drive. At least you have a new Litey and you're set to start burning like crazy!
Don't be a stranger now :)

One more thing.
DVD-shrink doesnt recognize the pioneer as a dvd-rw.

It is a similar issue to to RAM.
For example, you have 1 PC100 and 1 PC133 based ram sticks installed - you system will default to running at the lowest frequency PC100 (unless you have manually altered the clock rates).
The same is with PIO/DMA - if your dvdrom is reporting back PIO, then it will pull the IDE channel down to the lowest transfer method.
However if Windows had adjusted that, it could be changed within device manager.......
But it seems from your post, that the ASUS BIOS is reporting it as PIO - that is where the problem is, the BIOS is picking it up as PIO, so windows will do the same and the BIOS is what windows is referencing from.
I know you have it sorted now, but could you alter it all in the BIOS - maybe worth a shot if you still have the drive if you can............
Other than that, it maybe worthwhile reflashing the dvdrom's firmware to see if that clears the problem..........
...............PIO is no go, DMA all the way...............

So what is the solution to the problem you had helpful1? It seems that I have exactly the same problem, a DVD reader and a DVD burner plugged into the same IDE channel, the DVD reader is mastre and the DVD burner is slave, but the reader does not work with the error message
"The request could not be performed because of an I/O device error".
The burner works fine.
If I unplug the burner and only leave the reader on it works fine. Any suggestions?
Thank you.

Seems I'm 'late to the party'
The DVD-Rom wasn't a bad one, just an old one.
It will not play nice master/slaving with the burner, as you discovered in time...
Burner's just fine, as master, by itself.
I rip DVDs with my Sony 8x burner, works great.
Sure don't need second DVD reader.
@ panosk
So, pull the reader :-)
Or at least try the burner as master and the reader as slave.
You must have an old PC (or know someone who has a PC) that needs a DVD player...

The_OGS thanks for your answer, I will try switching master/slave, I had that in mind also, but I do not want to get rid of the reader since I want to have the option to burn DVDs from one disk to the other.
I was mainly wondering if I can try some other solution that involves software, like updating the drivers (I already tried it) etc.

You might be able to burn from DVD to DVD only if they are on separate controllers.
But it is not a good plan...
Attempting that using two drives on the same controller is nothing but a recipe for DVD-coasters.
No drivers or software will help.
Heck, even burning CDs direct (not involving HD) is always risky.
Any DVD should always be ripped to HD with DVDDecrypter, anyway, to remove region/protection/macrovision etc.
If you can get the 2 drives to play nice together, then that's good.
But right now it's the source of your problem, and offers little or no benefit to you in return...
Good luck :-)

So do you say that even if I can manage to make the dvd reader work I won't be able to burn from dvd to dvd on the fly?

I don't recommend on the fly copying. There's too much hanging in the balance that can go wrong during the process. Take your time and do it right I always say :)

Given that you have free disk space. For someone like me that usually my free disk space is no more than one gigabyte, copy on the fly is the only solution.

In that case I'd recommend reading at full speed and burning slow to avoid having the worthless "lossless linking" feature kicking in.
Keep in mind if you're backing up movies that are over 4.36 GB you're going to need to compress them and there's no way to do that on the fly.

I thought "on the fly" means that there is no (or only very limited) hard disk access. Is it not true?

It's true. On the fly for the most part bypasses the hard drive although it may use some of your page file in the process.

A modern 80GB hard drive is only $80 CDN ($60 USD)
And, maybe you could get 10 or 20 bucks for that DVD reader too...
Hard disk space is a necessity; burning DVDs is a luxury.
Seems you might have your priorities confused, panosk :-)
