Can't get rid of PIO, Slow burn speeds

[ER_Doc]

Hi all,

I have tried some of the tricks mentioned so far, but can't seem to fix this slow burn problem. My burner is a Pioneer DVR-109, connected in the 2nd drive bay as "Device 1" (my DVD-Rom is Device 0).

My configuration in the device manager is as follows. I have 2 "Primary IDE Channel" listed, and I don't know why:

Primary IDE Channel
-->Device 0 = DMA if available, transfermode = Ultra DMA Mode 5
-->Device 1 = DMA if available, transfermode = Not Applicable

Primary IDE Channel
-->Device 0 = DMA if available, transfermode = Ultra DMA Mode 2
-->Device 1 = DMA if available, transfermode = PIO Mode

Secondary IDE Channel
-->Device 0 = DMA if avail, Transfermode = Ultra DMA Mode 5
-->Device 1 = DMA if avail, Transfermode = not applicable

I have an 80 wire IDE cable as well. I believe that I clicked on all the of these IDE channels and "uninstalled" them to let them reboot on new install, and I still get that PIO mode. Any ideas what else I can do? I have a 16X burner that burns at 1X right now. It sucks!!!!!!

thanks for the help.

If all else fails, try this. But back up your registry first:

Re-enable DMA using the Registry Editor

Run REGEDIT. Go to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}

It has subkeys like 0000, 0001, 0002, etc. Normally 0001 is the primary IDE channel, 0002 the secondary, but other numbers can occur under certain circumstances. Check the DriverDesc value to see which one it is.

Delete MasterIdDataChecksum or SlaveIdDataChecksum, depending on whether the device in question is attached as master or slave, but it can't actually hurt to delete both. Reboot. The drive DMA capabilities will be redetected.

Open Device Manager again and check whether the device is now actually using DMA mode. If so, congratulations, you've made it (at least until the next time Windows disables DMA

Thanks redwudz,

I'm trying that now. I hope it works.


Update: This did not seem to work. Any other ideas? After reboot goes back to PIO mode

[redwudz]

That happens occasionally. Replace the IDE cable, just in case. Sometimes that will cause it. If you have any packet writing software like InCD or if you have any virtual drive programs like Daemon Tools or Clone CD, uninstall them as they can possibly interfere with the process.

If this happened after adding a drive, check your drive jumpers as interference there could cause problems. Two drives the same on the same channel can cause problems sometimes.

Make sure the auto detect in your BIOS is set properly or the setting for drives is correct.

If none of that works, maybe it's a problem with the drive itself.

I have had this happen a time or to. Ususally deleting the IDE controller (not the drive) from the device manager will set things straight. Ususally I have to reboot twice... Once after removing the controller, and the 2nd once it reloads the drivers.

[free is better]

have you tried uninstalling the dvd rom and making the dvd writer the master ? make sure the jumper is set correctly.

I think I solved this problem.

What happened is bizarre to me, but I found the fix. I had drive 0 as my DVD rom (samsung) and drive 1 as my DVD-RW (pioneer). When I checked the BIOS, the samsung was detected as drive 0 and for drive 1 there was nothing detected (granted I could still use the RW and it was functional except super slow burn speed). So I figured why not switch the 2 drives. I switched them so that now the burner is drive 0 and the ROM is drive 1, and voila---> drive 0 reads as pioneer, drive 1 reads as samsung.

Why the reverse configuration does not work is wierd to me, but I'll just have to live with it I guess because functionally I just like having my ROM drive above the RW drive in the bay.

So after I did this, no problem. Both drives are in DMA mode now. I don't what created this mystery, but at this point I can say I'm happy because I burned an entire SL DVD in the time it took me to type this reply!!!!

Thank you RedWudz and others for your guidance, suggestions, and time anyway.

This is an example of the drive incompatibility problem many do not seem to think is possible.

Some drives just won't master/slave, some only go in one particular order, severe performance slowdown is the symptom.

I have been told it results from timing differences in the command structure for the drives, don't know.

My first step in diagnosing such a problem is ALWAYS to go to single drive on the cable and test that. Then add the second drive, if the problem goes away and comes back, problem is both Isolated and Identified.

[redwudz]

Good point, Nelson37. I had assumed this was a new problem with a existing drive that was working properly before. If the drive has always been PIO from the time it was installed, that points to a hardware problem. If it was DMA and changes to PIO without any hardware changes, that would likely be a software issue.

Apparently some drives and probably some IDE controllers need to be set up with the burner as master. But I have used several in the slave position with different MBs and they have always performed in DMA mode. A further difficulty would be two burners like that on one channel.

EDIT: And ER_Doc, you can change the physical position of your drives and leave your cables and jumper settings the same, if your IDE cables are long enough. That's what I do most times as I prefer my ROM (Slave) above the burner (master).

It's a known fact that PIONEER drives should be set to MASTER or it won't work correctly.
