This condition is caused by spyware,hard drive problems. First create a restore point, then run this script http://winhlp.com/tools/resetdma.vbs reboot and should do the trick. After XP tried to access the hard drive without success for any reason there is a register counter that downgrades the speed of the hard drive to PIO. Good Luck!

Go to Control Panel - click on System - Click on Hardware - Click on Device Manager - click on IDE ATA/ATAPI Controller.
Then right click on Primary IDE Chanel - then click on Properties - Then Advance Settings - For the Device 0 in Transfer Mode select DMA if available. Then Click OK.
You can also select DMA for Device 1 too

How do i fix an unexpectedI/o error


Could be when windows uses transfer mode, you can change this mode
Steps To Change IDE Properties
Click the Start button
Right click My Computer
Select Manage from the resulting menu
In the Computer Management window, select Device Manager
In the right pane, click to expand IDE ATA/ATAPI controllers
Identify your CD/DVD drive in the expanded menu and right click the appropriate drive
Select Properties
In the Properties windows, click the Advanced Settings tab
In the Transfer Mode box that represents your CD/DVD drive (typically Device 1); open the dropdown menu and select PIO Only
Click ok and exit all windows
If this does not resolve your issue, then you will need to go back using the above procedure and change the Device 1 in step #9 back to "DMA if available". Then, change Device 0 to "PIO Only" in the Transfer Mode box.
For reference, the Device 0 is the Primary IDE Channel and the Device 1 is the secondary IDE Channel.
After you change your settings, make sure you restart your system so that the computer recognizes the changes you have made. After you reboot, check the settings to make sure they are in effect. If they are, your device should now work properly.

any further help let me know

Video playback stutters is choppy when the video plays it stops and stutters on a frame. it will play for a few seconds then stutter.


I had a problem similar to this and eventually traced it to the wrong mode setting on the DVD drive's transfer mode.
To check the setting, open Device Manager and then double click on the IDE controllers item. Double click on IDE channel (if there's more than one you'll need to check each one) and then select the Advanced Settings tab. On this tab should be up to two devices and each should show under "Current Transfer Mode" soemthing including the word "DMA".
If any device shows "PIO", then this is probably the problem.
If you Google "PIO versus DMA", one of the top results has a really good article on why this happens and how to force Windows to revert to DMA.

Trying to set DVD-R/W to DMA mode, currently stuck in PIO


you are trying which is not possible. all optical drives work in PIO mode ... hard disk typically run in DMA mode which is bypassing cpu to access memory directly without calling daddy CPU.... though i am amazed who offered you registry fix for this.

CDR/DVD R Drive Repair


First of all, I would recommend you to copy the movies or audio files to the Hard Drive and play from there as it is not totally recommended to play audio or video files from the DVD Drives directly which may reduce its life span.

For DVD Videos, you need to copy the Video_Ts folder which containt the video files.

Sort out the files according to file types and files with .Vob are the video files which can be played.

However, if you are not comfirtable with the above instructions, try the steps listed below which I use to resolve this kind of issues :

Step 1:

1. Click Start.
2. Right-click My Computer (My Computer is on the Desktop for versions of Windows prior to Windows XP).
3. Click Properties.
4. Click the Hardware tab.
5. Click the Device Manager button (Device Manager is a tab in versions of Windows prior to Windows XP).
6. Click the plus sign (+) to the left of IDE ATA/ATAPI controllers to expand this list.
7. Right-click Secondary IDE Channel.
8. Click Uninstall (Click Delete for versions of Windows prior to Windows XP).
9. Restart the computer.
10. Repeat steps 1-7.
11. Click Properties.
12. Click the Advanced Settings tab.

Verify that the transfer modes for both Device 0 and Device 1 are set to DMA if available.
13. Click OK and try playing a DVD.

i) The current transfer mode should read some thing like "Multi Word DMA Mode 2" or "Ultra DMA Mode 5" under Advanced Settings tab after this.
ii) The above procedure applies only to certain model notebooks. If the Secondary IDE is not listed, then this step will not help resolve the issue.

Step 2:

DMA setting will not stay enabled after rebooting (OR) switches back to PIO from DMA during startup:
IN this case, Please download/install of Notebooks Windows XP Registry Patch to Reset DVD Mode from PIO to DMA from:

ftp://ftp.hp.com/pub/softpaq/sp20501-21000/SP20531.exe


Step 3:

You may experience stutter, echo, or distorted sound if the hardware acceleration is not set correctly. To experience good audio quality, adjust the hardware acceleration slider for speaker in the Device Manger by following these steps:

1. Click Start and then Control Panel.
2. Click Sounds and Audio Devices.
3. Under Speaker settings, click Advanced.
4. Click the Performance tab.
5. Change the Hardware Acceleration slider's position.

NOTE: The slider can be positioned from "none" to "full" depending on the usage.

6. Click Apply and OK.

Repeat steps 5 & 6 till you get optimum audio performance.

Step 4 :
BIOS Reset
1. Restart the notebook.
2. Tap the F10 key as soon as the HP logo appears.
3. Using the arrow keys, navigate to Exit menu and select Get defaults values.
4. Navigate to Exit menu and select Save Changes and Exit.

Even this steps look lengthy, they should resolve the issues.

Check the status of the device in Device Manager to make sure that the device driver is working correctly. (If you need help doing that please ask.)

If no joy then:
Change the transfer mode for your CD drive in IDE Channel Properties loadTOCNode(2, 'resolution'); loadTOCNode(2, 'resolution'); 1. Click Start, right-click My Computer, and then click Manage. 2. Under Computer Management (Local), click Device Manager. 3. On the right side, expand IDE ATA/ATAPI controllers. 4.

On the Advanced Settings tab, in the Transfer Mode box for the device that represents your CD drive, click PIO Only. Typically, this device is Device 0. Then, click OK. If the issue is not resolved after you change the transfer mode for the secondary IDE channel device 0, your CD drive may not be located there. Use the same procedure to change the transfer mode back to DMA if available. Then, repeat these steps to change the transfer mode for IDE devices in the following order until the issue is resolved: • Primary IDE channel, device 1 • Secondary IDE channel, device 1Note Primary IDE channel, device 0 is connected to your boot disk. This is the hard disk that typically contains your operating system.
