Just to make it clear ...http://support.microsoft.com/kb/314060
is one of many many references to UpperFilters and LowerFilters, as mentioned above.
There are NO entries for these in my registry.
The additional elements of http://support.microsoft.com/kb/314060
require the drive to show in the Device Manager.
Other things I've now tried;
I swapped the old DVD back, it showed in Device Manage self installed. I uninstalled it again incase it didn't take last time. I swapped to the new DVD, and it still didn't show in Device Manager. (Yes, it still looks fine in BIOS and works off my other boot)
I tried moving it's connection around every sata port on my motherboard. (Slightly OCD
) Results never different.
I tried the new DVD in another computer running XP-Pro SP3 and it worked fine.
I'd think I must have done something to XP when I tried to get my old DVD working before I established it was the DVD itself, but I formatted my windows boot partition and loaded a ghost.
Doh! Didn't try the esata ports on the case. It's ugly with the cable looping back into the case, but the new DVD drive works fine off them.
