Please help! i'm clueless

STRANGE!!!. I did some various tests on the TDK (i'm still waiting for the RITEK) DVD+RW and what I found was that the SAME disc that did not work once (said illegal disc) worked today perfectly. What I did was try to erase each blank disc through NERO, this makes the disc formatted and improves it's performance. WEll as I stated the discs that said illegal disc error during the erase yesterday worked today with no problems. THE SAME DISCS!!!. So is this just a result of "cheap media" or marginal media, or is this something unique with my computer. thanks. BTW, No additional programs worked in the background.

 

Yes ... bad media. Nero will recognize good RW media and set up to write right away.

Am I reading your latest post correctly, in that your results are different than before?

 

Here's the thing: What I noticed is, with bad media that is (tdk, fujifilm) is that if you put the disc in and erase it through quick-erase in Nero and the erase is successful, then the disc will work during back-up. Why? because the quick-erase function formats the disc.

SO i tried this. Yesterday, I tried about 5 TDK DVD+RW discs and NERO WOULD NOT ERASE THEM. It said ILLEGAL DISC. TODAY, I tried the SAME 5 (about 5) discs and they erased perfectly.

what i'm wondering: is this just bad media or something else, like a bad drive.

 

Bad drives tend to be consistent - either good or bad. I know that what is happening defies logic. It's the media ... in combination with your drive ... in combination with the software. You might get different results with a different drive, but why would you want to stay with crappy media anyway?

I ORDERED RITEK RIDATA DVD+RW, SO MY BAD MEDIA DAYS ARE OVER. BUT THE POINT IS BEFORE I TRY OUT THE GOOD RITEK MEDIA, I REALLY WANT TO GET TO THE BOTTOM OF THIS ISSUE. I WAS ALWAYS A FIRM BELIEVER IN LOGIC NOT CHANCE, AND I AM STILL (EVEN AFTER DOC AND PETE'S EXPLANATIONS) BEWILDERED BY THE FACT THAT THE VERY SAME MEDIA THAT DIDNT WORK BEFORE WORKED NOW.

BUT I CAN'T SAY ANYTHING WITH REAL CREDIBILITY UNTIL I TEST THE RITEK. IT SHOULD WORK FOR THE FIRST TRY RIGHT?

 

First, please don't use capitals. It's rude. Read the rules.

Second, you are obviously a logical person looking for a logical answer. That's why I mentioned logic. To get a little more detailed, different manufacturers use different dyes, and their manufacturing processes vary. Drives also vary in their ability to read info. If you really want to understand all this, there is a load of research data on the web that makes for some pretty dry reading, and if you are really determined to wade through it, I think you will begin to understand.

Third, if Ritek doesn't work for you, you will be the first person I've ever known about. As far as Ritek "working the first try" ... it sounds like you are trying to shift responsibility to the people kind enough at AD to give you well-founded, free advice. Please understand that your problem is ultimately your responsibility. And, it is certainly your option to not follow the advice given to you.

mindgod...

This is a start on some research. Search "DVD Dyes".

A low-grade dye will have "pits" with poorly defined boundaries, and these can also deform into adjacent pits. Dye stability is also an issue with RW media. And, you also have to have an electro-mechanical device that must be tuned just right to read, but mostly write, these nano-sized pits. Too much laser and you get a big, oversized pit. Or, the dye may not be matched for your drive's lazer, which means a normal pulse could yield a big pit. The dye layer must also be precisely applied, or results will vary. All of this makes for a marginal situation. And, this is just the start of the variables that you begin to deal with. Here's a link about just how small these pits are, and their spacing. It's easy to see how they could overlap.

Yes, conceptually, things should work, and this is the logic of it. In practice, there are a lot of variables we don't take into account. Media is the biggest variable we deal with.

Could your problem be something else besides media? There is always that chance that something was overlooked.

Yep, the "Doc's" right, there're soooo many problems that are media releated - most have no idea -

As long as we are discussing media, here's another link that may answer some of your questions - and if you want to do DVD backups, you should have questions -

DVD's Demystified may answer some of those questions -

@ ScubaPete...

Hi Pete. 'Have another one going over here that I believe is a media problem. Classic symptoms. Wonderin' if you'd have a look and see if you think it might be something else?

(PS: Where's the shark?)
