NEC 1300a BURNS FILM OK BUT NOT DATA! HELP PLS

Hi. Any help with my problem would be great.

I have a NEC ND 1300a DVD Burner recently flashed with 1.0c firmware.

The problem I am having is with burning DVDs with data files on them. The burn process finishes perfectly, however when I try to access the files on the disk I get Cyclic Redundancy Check for every file! The discs are not dirty and do not look damaged in any way, leading me to believe it is a compatibility problem.

However, if I back up movies and run them on my stand alone DVD player (Logix DVD 3000) the film runs sweet as a nut! Running these backed up films via my NEC 1300a burner causes the film to be jerky and pause a lot.

The DVDs I am using at the moment are “Ridisc 4x dvd-r with white printable surface”. They have ritek g04 dye which I though was supposed to be good (probably is if they would work!)

The Media Info from a written disc (with 24 .avi files and 1 .jpeg file on it) is shown below including the complete media code.

I have successfully written data discs using this drive with different media (Imation and Traxdata 8x DVD+R) and have ran a test on each media using DVD Info.

I have indicated in the media code above (using an *) the fields of data that are NOT present when running a scan of disc the Imation and Traxdata discs.
After reading the help file in DVD Info I found out that these fields are present on newer discs and allow the media to tell the burner at what speed to burn the disc (and other laser info), rather than relying on media support from the firmware. I have a feeling my problem lies in these fields because it’s the only difference I can see between the “good” and “bad” discs that could pose a problem. Any help with my problem would be great. Thanks

Well… looks like your NEC 1300a isn’t much of a reader :wink:


#3

Thats what I thought, but i tried the disc out on another computer with 2 dvd drives, (one a Phillips DvD 8421 and I am unsure of the other ones make or model), and I have the same errors with those drives

It could be bad media.

RITEK G04 varies very much in quality.

I can only burn mine in NEC 2500A and in my NEC 3500A.

Burns only at 2x in Plextor 712A FW 105 with a lousy result.

Benq 1620 FW B7T9 give my write error.

JBV - Thanks for your input. Do you own a NEC nd 1300a? If so what media do you use in it, and do you get good results burning data (not dvd video backups) with your discs?


#6

No I don’t own a ND 1300A.

If your data are very important, you better use high quality media.

I use Verbatim +/- disk, when I am storing data or home video.

I had a similair issue with Ritek DVDs (+R). I found out that there is something about the preformatting on the Ritek dvds (+r at least) that the 1300A hates. It is like it reports the wrong size disk to write on. I started using ASO dvds (+R) from those Meritline guys, and worked good after that. Mine is at 1.0B (original BIOS). My drive is a Pacific Digital, but is basicly a NEC 1300A in their box. No modifications…
