After I installed Windows service pack 3 my computer will not boot up past the screen with the little white dot moving. After it boots up I can plug in the Western Digital External HD and my PC will recognize it. I have been in touch with Microsoft support re problems with Service Pack 3 and we have gone through everything, including updating the system BIOS.
Don't know if this is related but my system cannot find the path to the ScsiAccess.exe program.
They did tell me that SP3 is not compatible with the 1394 feature component. Does anyone know of how to get around this other than a hotfix that Western Digital has not come out with yet.
