Is this bad media? or bad a drive?

Hey everyone. I just got a new liteon 812 the other day. I also bought 20 dvd+r’s. They are verbatin disks. 5 out 6 of my dvd’s i’ve tried to burn have either failed to burn, or have completed burning and then not allowed me to read them. (When i try to read the disks, it just sits there clicking and stuff) I’ve verified that those disks cant be read on my father’s dvd either. (he has the same liteon 812 as i do)

I knoticed something interesting however while looking at these disks. It seems that all of the bad disks have what appear to be damage around the edge of the cd. i dont know how to explain it. I took several pictures of this damage and i’d like to know if anyone knows if this is causing my problem or if this is normal. The only disk that has worked so far has not had this damage. That is why i believe that i bought bad media.

The pictures below are sized down because i didnt want to mess the thread up. To see a large quality image, please click on the images them selves. Thanks!!

I’d appriciate any help you can provide!!!

What’s the media code on these discs?

BTW, nice pics, what kind of camera?


#3

Sorry. I’m at work right now. When i get home i’ll check the media code.

I used my Nikon D100 with a Nikon 60MM F2.8D AF Micro-Nikkor Len. :smiley: Its my crime scene evidence lens. :smiley: Its a very nice lense. :iagree: That last pic was a dud, but oh well. You get the idea. :smiley:

Anyway, I’ve seen a variety of wierd imperfections in the hub of discs. You want to watch that, as cracks often follow these kinds of things. Doubt that it is related to the reading issue per se, unless there are other imperfections in the dye or stamper.

probably mcc003s from sigapore…thier not the best disks in the world…though you shouldnt get undreadable disks. what version of firmware do you have on your 812 i suggest getting USON or US0Q to burn them at 8x. see if that fixes your issues. the notches in the inner ring are from the pressing some machines leave distinguishing marks i dont think its a defect.

Hey. I just ran that program and this is what i think you want. Sorry if its more than you want. :smiley:

It looks like Jamos was right. They are mcc003’s. I’m going to take them back to the store tomorrow. :smiley: I’m going to get these:

Anything else you’d reccomend?

I seriously doubt Prodisc is going to give better results than Mitsubishi media. I’d say you are extremely unlucky and just got a bad batch of the Mitsubishi discs as overall they give fairly good results in most burners from the tests I’ve seen and done myself (I have the same drive you do). Let’s hope it’s not your drive at fault.

those are the sigapore ones…ive gotten so so burns with this drive with them…the tawains do alot better.

did it say made in sigapore on the lableing?

I’ve had bad experiences with the mcc003 media made in Singapore too. I’ve got maybe three left from a ten pack and later this week I plan on trying one with US0Q but with US0N they suck. I tried one at 4X and it did ok but not at 8X. I don’t reccomend geting prodisc from acca since I had to send a whole spindle back to them for doing the same thing the mcc003 did. So far, the best 8X media I’ve found for the 812S is Legacy from Newegg.com.
P.S.
Please don’t buy it all up. I’ll need some later when my spindle runs out.


#10

Very strange…I’ve always gotten good results from MCC003 media made in Singapore, on both my 812S@832S and my ND-2500A. I guess it’s just one of those things where it works for some people and not for others, even on the same drives.


#11

I think Prodisc 8X +R (R03) have mixed review here. Check the DVD Media forum.
4X TY or 4X Ricohjpnr01 should do at least 6X with great results if not 8X.


#12

Well I’m not having any problem with Prodisc’s here on my 812s. :slight_smile:



#13

It would be very nice to see a scan or 2 of the offending MCC discs. If we can persuade MattRK to post them. :wink:
We also don’t know what FW he is using, it may just be that he needs to update it.


#14

yes matt please do a kprobe scan of your bad burns. also i would suggest upgrading to USOQ firmware. Ive gotton great burns with mcc003s too just not great ones with the media code he has there are two different mid codes of mcc003s out there for more info look at this thread

Thanks for all the replys. I’ve been busy for the last couple of days.

Well, i started out using the stock firmware that it came with, which i think was USON. I then upgraded it to the 832 firmware, which ever was the latest at the time. After that, when the USOQ came out, i upgraded to that. And that is what i have now.

I have only had one successfull burn so far, and that was with the 832 firmware. None of my other attempts have succeeded. (even with the 832 firmware)

I have tried to use kprobe on the bad burns, but i can not get the drive to read them. All it does is make clicks and pops for a few seconds. Its like the drive isnt spinning the disks up. My father’s 812 wont read any of the disks either.

I’m going to try to burn another one here in a second. If it works, i’ll use kprobe on it and let you know. I’ll also try to post the kprobe results from the very first good burn i did.

Also, all the disks i have are labeled as being made in Singapore. I bought them at Sam’s Club. I may go back today and try to retrieve some more of them. They go pretty fast there, so i’m hopeing that they’ve already gotten a new shipment in and that they arent the same batch as these.

Consistant with an unreadable lead-in. Can we assume that other media brands work alright?


#17

Ok, i’m trying to run kprobe now. but as i’ve never actually run it before, could someone give me a quick rundown as to which settings i need to have set for a basic scan?

-Matt

kprobe2

As far as i know it works fine with other brands. It burned the two sample dvd’s i got with the drive just fine. I exchanged my bad media today for some others. (same brand) I’m going to try them out tonight when i get off work. If i have the same problem, i’ll just return those and get a differnt brand. I might try some -r’s.

Btw, i didnt have time to post my kprobe results because it was takeing so long. It went pretty fast untill the very end when it slowed way way down. It was reading at .01x. Hopefully when i get home, its done and it worked. I dont know though. I’ve never used the program before. :smiley:

I hope to have more news for you shortly. :smiley: Thanks for everyone’s help. I appriciate it very much.

kprobe 2 should be steady at 4x if your drive is working properly…make sure you choose 4x speed…should only take 12 min. or so. make sure to run it from your 812 burner too.

if you had it at max speed and it slowed down at the end then that means your burn wasnt very good.
