I have a NEC nd-3540a dvdrw drive.  It is no LONGER recognized as this drive in windows.  Device manager shows it as "Generic DVD-ROM SCSI CdRom Device."  The drive will not read or recognize anything I put in.  But, it still shows up as nd-3540a in the setup before windows loads.  Does anyone know what I can do about this?Delete it in Device Manager and reboot. Let us know what happens.I've tried this, and it just reappears as the generic drive.Can you try this drive in another machine? How old is it? Have you checked the manufacturer's web site for known issues or firmware updates?I don't really have the means to try the drive on another machine.  It's less than a year old (the whole computer is) and I haven't read or heard of anyone else having a pproblem like this.I have PLENTY of times when the optics in the drive are shot. It opens and closes fine because that is MECHANICAL. Windows can identify the make and model, but it doesn't work. Has it had a lot of use? SOmetimes they just die without that, but there is a reason those things generally COME with a 1 year warranty. If you have had it less than that and have purchase info I would contact NEC. If not, probably time for a new drive. (They are now down to about $40!)Fair enough.  It might be WORTH the $40 to not have to deal with it.  Thanks for all the help.
