Hi there.

I had a similar problem once and searched till I found my answer.

I don't remember the sites but I stored the important facts for tweaking my pc.

Windows XP will turn off DMA mode for a device after encountering certain errors during data transfer operations. If more that six DMA transfer timeouts occur, Windows will turn off DMA and use only PIO mode on that device.
In this case, the user cannot turn on DMA for this device. The only option for the user who wants to enable DMA mode is to uninstall and reinstall the device.
Windows XP downgrades the Ultra DMA transfer mode after receiving more than six CRC errors. Whenever possible, the operating system will step down one UDMA mode at a time (from UDMA mode 4 to UDMA mode 3, and so on).

How to disable the DMA-shutdown mechanism
1. Install Microsoft Service Pack 2 for Windows XP!
2. Press Windows-key+R and enter regedit in order to open up the Registry Editor. Expand the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0001. Right-click into the right part of the window and select New/DWORD value. Name it ResetErrorCountersOnSuccess, double-click on this value and enter 1.

3. Repeat this step with the subkeys 0002, 0003 (etc.) if they exist. After a restart the DMA-mode wont shut down anymore and therefore delivers you high speed performance while accessing your data.

Hope that helps. Good luck.

To be a little more specific regarding the absolutely correct suggestion that, "The only option for the user who wants to enable DMA mode is to uninstall and reinstall the device":

To accomplish this:

From the Control Panel open the "Device Manager"

1) Right click on the applicable channel in Device Manager

2) Click on "Uninstall"

3) Reboot

After rebooting, go to "Device Manager" again and change the setting to "DMA if available".

If your O/S is WinXP, the re-establishing of DMA is now complete. If your O/S is other than WinXP, rebopot one more time...
