Hi, I have a _NEC DVD_RW ND-3550A DVD burner and it has completely stopped working. It will not recognize CDs, DVDs, CDRs, or DVDRs. Explorer asks that I insert a disc after the drive stops trying to read the disc. I have already upgraded the firmware to the latest version and I have just finished checking the IDE and power connections. I have also uninstalled/reinstalled the device from the device manager. I find this problem rather annoying, as my hard drive is getting full with things that would be better off on a DVD. To top off the problem, my other DVD drive (not a burner) refuses to read any burned media. I have experienced this with many computers, although never to the point where no discs would work at all. Does anyone have any suggestions?
