I found a solution, how to fix the vista-driver-problem
for my SONY-DVD-RW :
Windows Vista:
Driver-problem : CD/DVD-Drive doesn't work anymore
( Errorcode 39 ) Tecnical problem
It is a known ERROR in Windows.
Mostly, it can be a problem with a burning-suite.
To make the CD-drive working again :
1. Start REGEDIT
2. Look for : "HKEY_LOCAL_MACHINE" > "System" and
"CurrentControlSet" > "Control" > "Class".
3. Open {4D36E965-E325-11CE-BFC1-08002BE10318}.
4. There you have to delete the Registryvalue "UpperFilters"
and "LowerFilters"
The CD-drive will be visible again.
