Verification errors

Hi I’m using a lite-on SOHW-832S. I have the latest firmware. And I am burning at 8 x with Taiyo Yuden DVD-R media. The problem I am having is that every now and then, for no apparent reason, I get read verification errors, and part of the data I have burned to disc will be unusable. I never even did read verification until one day I took out a disc and found I couldn’t read some files on it. Since then I’ve been verifying every burn: most go fine, but every now and then one doesn’t. And the usual result is that on the disc with read verification errors a few hundred MBs of files are unreadable.
I am wondering what would be causing this problem. Bad burner? bad media? Or should I just be burning at a slower speed?
If anyone could help me out I’d really appreciate it. Thanks.

Here is the end of the log of the last burn I did which gave me verification erorrs:

I don’t know anything about your burner, so I’ll leave that for others to comment on. The media shouldn’t be the problem, as TY’s are considered to be one of the best, if not the best. (I trust that you have real TY’s, and not fake?)

Maybe it’s your system memory? See this thread…
http://club.cdfreaks.com/showthread.php?t=166578

If it does a few complete passes OK, stop it, set it to do test 8 only, and let it run for at least several hours (eg; overnight, or whilst out for the day).

Colin

Please don’t post serials. :wink:

Use a better tool like Nero CD DVD Speed or DVDInfoPro to verify the content / data / disc.

Yes the TYs are genuine.
I’ll try leaving memtest on some night soon, as you suggest, and see if I come up with anything that way.
Anybody else have any clue what might be going on?
I just ran CD-DVD Speed on two discs containing MP3 files which give me read verification errors. What I found is that the discs show a small number of bad sectors and some damaged sectors as well. On one disc only actually two files were rendered unreadable, on the other about 15.
I don’t know if it’s just a coincidence, but in both discs the bad sectors show up in around the same place: ~3700 - 4000 mb.

From that description then it’s probably not your memory, but it won’t hurt to test it. Maybe you’ve been unlucky and got a bad batch of TY’s? If you don’t have any other media laying around that you can try, maybe just buy one or two singles of something available locally, and see what happens with them.

Do you still have discs from previous batches that you can scan now, to see how they compare?

Colin

I can’t figure it out. I tested some dics from a previous bath of TY’s and I found one which has the exact some problem: some bad sectors, rendering a few files unreadable. Now I’ve become quite concerned, because I’m thinking I probably have been losing data randomly while burning my DVDs over the past year. What makes it more difficult to figure out is most of the DVDs seem ok. But now and then one comes up which has some bad sectors. Could my burner be defective? Or would I get better results if I burned at a slower speed, like 6 x rather than 8 x?
What’s strange is when I first got my comp about a year ago, I had probems with the DVDRW that came with it, an NEC. It refused to read any files written on the last part of any DVD I put in it. Also, when I burned DVDs with it, the data at the end of the disc always came out as unreadable on my other DVD burners.
So this Lite-on was sent me as a replacement drive.
Could problems like this be caused by a glitch within the computer hardware of the system itself? Or is it always related specifically to the burner and media, and I just ended up with two flakey burners in a row?

I’ll leave comments on those burners to those who are more familiar with them. (My current burner is a Pioneer DVR-A10XL. Before that I used a Pioneer DVR-A06.)

my other DVD burners

If you still have other burners and computers, I’d be swapping things around at this point, with a view to narrowing it down that way.

Colin

Maybe I’ll just get a Pioneer like you to replace my current drive and hope for the best! I’ve always heard Pioneer makes the most dependable drives.
I made a mistake when I said burners, I meant drives that can read DVDs.
I have been verifying more discs today and found a definite pattern. All of the bad sectors seem to come when the scanner reaches around 80%, in the 3800-4000mb range. This is the case for every single disc that has bad sectors. Doesn’t that seem like a bit of a coincidence? Only problem is I have no idea why that would be. Makes me think it’s not the media though, because you’d think if the media were bad the bad sectors would be popping up all over the place.
I also read that it is best to use DVD+R media with lite-ons, rather than DVD-R, which is what I am using. That is the only thing I can come up with in terms of my doing something wrong. But still doesn’t really seem to explain why bad sectors pop up in the same area of the disc on every failed verify!!!

One of the “features” of some low-grade discs is poor dye spread towards the outer edge, which then manifests itself as errors / skips as you get towards the end of the disc. But this shouldn’t be the case with genuine TY’s.

Yeah, maybe it’s just a faulty writer. At least going out and buying another one isn’t the expensive option that it used to be.

Out of curiousity, does it make any difference if you disconnect the Samsung CD-ROM drive that’s a slave on the same cable as your writer? And is your system “up to it”? eg; What’s the theoretical achievable write speed in simulate mode?
