Pioneer 111L only writing at 1.9x speed don't why. Please Help

[bnbhoha]

I have two dvd writers in my computer; NEC 3520 and Pioneer 111L. Since day one the Pioneer has been writing at about 1.9x speed. I have three hard drives in my computer & thought perhaps sharing an IDE cable with a hard drive was doing this, but the other two aren't on the same cable and I get the same speed with all three. I have DMA if available selected on both the IDE channels. I was hoping someone could provide some insight. I don't get it. I checked the

I suspect you have used all of your DMA channels for other devices.

I put an ATA controller card in thay gives me two additional channels on top of the two that are on the mother board, so I can attach a total of 8 devices.

Here's my setup. Everything is on cable select.

C: is on main IDE going to the mother board and not sharing 2nd channel

NEC drive IDE is going to mother board and not sharing channel

Pioneer Drive is sharing IDE channel with my Z: drive (60gb hard drive) and going to ATA controller card

H: (120gb) is not sharing and going to ATA controller card

Set your drives on that controller card to master/slave that's why your drive is only burning at slow speeds. Never use cable select. Don't hookup a dvd burner on the same channel as a hard drive. Use your controller card for your hard drives and the ide channels on your mobo for your dvd burners.

The only way I can get the Pioneer to work properly is to connect the Pioneer as master on IDE channel 1 and my hard disk on IDE channel 2, but then my NEC 3520 writer goes into PIO mode when it's Slave. It seems I will have to choose which writer I want to use. Neither of them will write fast if they are on the controller card and I can only connect one of them as the master on IDE channel 1

Any system has a limited number of DMA channels. Adding controllers does not give you any more DMA channels.

You have discovered that you can't have all of your hard disks and writers in DMA mode.

Unless you can find drivers which allow DMA sharing, you are stuck where you are.\

Which is why I suggested you put all of your hard drives on that pci controller card. Then put your dvd burners on the mobo ide channels using the master and slave settings. Buy a new 80 wire ide cable as well. I have 2 computers that uses a pci controller card for hard drives then each one has 4 dvd burners on the mobo ide channels. Works flawlessly. Using cable select settings will give you problems.

Also if your pci controller card chipset does not have the silicon image 680 or the ite 8212 chipset then your dvd burners will not work correctly. I suspect your pci controller card has the promise chipset which is suited for hard drives only. Long ago I tried to use a pci controller card that had the promise chipset and it would not work correctly if I hooked up a dvd burner. I use a ite 8212 chipset controller card in 1 of my computers that has 2 dvd burners hooked up to it.

I have 4 HDD and 2 optical drives in my computer all operating in DMA mode.

Setup:

1st HDD IDE 0 Primary > Master = DMA5
2nd HDD IDE 1 Primary > Slave = DMA 5

Pioneer 108D Burner on Seconday 0 > Master = DMA4
Lite-on DVD Reader on Secondary 1 > Slave = DMA 2

ATA100 Card with 2 Masters = both DMA5

All drives are connected with 80 conductor cables.

Hope this helps

Is there a blinky88 problem? None stated.

No .... I have never experienced a problem of any descrption with this configuration.

I have never used cable select on any of my internal devises.
