First, I want to thank those who tried to help.
Second, I was able to ‘fix’ the problem.
Then sadly, I was unable to implement the solution offered by Wombie.
For some reason (known only to Windows) I was never able to get to a Device manager page that was labeled Settings.
Under Device Manager, when I doubled clicked on HP DVD Writer 1040d I was shown a Window with five (5) tabs.
Clicking on any of these tabs (and on buttons within these screens) never presented me with a Settings screen.
I used Windows XP Help and Support and searched on DMA Settings and as I recall the instructions there told me to click on the Resources tab under Device Manager and if I didn’t have a Resource tab then I was not allow to change the DMA setting.
In any case, it seems that I am unable to get to the Settings screen in the Device Manager.
Next thing I tried was uninstalling the drives - there was a button in Device Manager that permitted that. A Re-boot, installed the driver and a Nero “Test Drive” indicated the problem remained.
So, I did a System Restore, going back to Monday a day I recalled that the drive was working correctly.
That ‘fixed’ it. A Nero “Test Drive” was reporting 10x transfer rate and I could hear the drive speeding up when I canceled the test.
Again, thanks for all your attempts to help and this is the [U]first time[/U] that CDFreaks has not been able to provide quick and effective advice.
I guess you can’t win’em all.
