I'm not an xp wiz, but
did you try *uninstalling* the driver (and the hardware) then re installing? --fj
I recently applied an firmware upate from Sony to my system for my DVD Drive running under Home XP. Since that time on every re boot I receive a message that the system has found new hardware - my DVD drive - and needs to reinstall it. Yet when I say re install it says it can't find the driver. I tried directing it to the appropriate file on the install disk with no success.
One response from the XP forum said to delete the Reg entries relating to the DVD and then it would be reinstalled. I have been hesitant to do this since I have some concern that since it cant find the driver now it will not find it if I delete the reg enteries, and the Drive seem to be working OK. The problem is the annoying appeareance of the wizard. Sony tells me to get the driver from its' web site but It's not there that I can find.
