Question about NEC NR 7900A (NR7900) CD-RW Burner

Wont recognize burned disks

MY NEC NR 7900A CD-RW Burner cd rom will not recognize disks that have be rewritten (burned). It will recognize audio cd's that I have for example bought in a record shop. When i placed a burned cd into the cd room it makes noises as if its recognizing the cd then abruptly makes a *click" sound..it repeatedly does this...unti a point when I guess it marks the cd as unreadable. Is this a device defect? My comp is a dell inspiron, approx 6 years old.

This does sound like a defective drive, most likely a laser / reader issue, because the refractive properties of the CDR is different from a "pressed" disk it looks like thia failed TOC seek issue, the head starts at the center of the disk and reads outwards, the click noise is most likeley the head reaching the terminus (the outer limit of the motorised movement), the drive then unable to find the TOC gives up and decides the disk is unreadable. if this drive is within the manufacturer's Warrantee period I would reccommend sending it back.

The reason your DVD R was not read- is the drive is a CD-RW, meaning it can read CD, CD R, and CD RW disks- NOT DVD, DVD R, DVD RW

Write to CD

Hi.
This is common. It usually means the laser diode is too weak to burn the layer on the disc, or the lens has lost it's clarity. This means the optical pickup assembly requires replacement. Probably time to replace the drive.

It Sounds like you need a CODEC, to DECode the movie, so that it will burn it. Try this: goto http://www.dvd43.com download the decrypter. Install it, and you should be able to burn most, if not all the newer DVD's.
Let me know if this does not work for you. If that happens, let me know what version of Windows you are using
