[qanda]This thread is about the NEC ND-3450A. Click here to see full specs[/qanda]I have a NEC DVD±RW ND-3450A and an HP 840d DL burner. Problem is that both the roms for them and my 2 virtual roms quit showing. In control panel and device manager, they all show up with yellow errors next to them. They also show up in my bios. Anyone know how i get them to be read again by windows without having ot reformat or restore to my Norton Ghost image?
