My question is "How do I make my new two SATA Plextor PX-L890SA DVDRs functional on a 64bit WIN 7 OS? Device Manager (general) says "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing (code 39)".
I then installed an IDE Sony DRU 840A DVDR and got the same message. The device manager correctly identifies these units.
The path is C:\WINDOWS\SYSTEM 32\DRIVERS\CDROM.SYS. If I try to update the driver, it says "the best driver for your device is installed"
I have uninstalled the driver but get the same message back.
I am a novice at this, since I naiively thought that I could just install these and they would automatically work.
