Eric, thanks for the opinion. I might agree, but notice that the "problem"
goes away with a power-off re-boot. This issues a reset to the controller,
but it cannot be a controller problem since my DVD drive shares this same
controller and does not "go away". The VAIO is not brand new, but was
originally delivered with WinXP/Home, so I am sure the drives are fully
ATAPI compliant. I was hoping that others have seen and solved this problem
on Pentium IV PCs.
