I have to burn a lot of DVDs for my business, and rarely have trouble doing so.  The master of one I've been trying to copy is fine, and works all the way to the end.  However, every time I try to burn a copy, I get the following error report:  "Unrecovered read error - Medium error."  [03/11/05].  I've even tried switching the source and destination drives, all to no avail.  I also cleaned the burners with a lens cleaner disk, which cleared up some other problems I'd been having, and I should have thought of doing this long ago (duh!).

Since there's nothing wrong with the master (just looked at it from beginning to end; yawn), I'm wondering why I keep running into this problem and what it means.  Can anybody help?  The master is irreplaceable, and it looks like I never made a backup copy, which is rare.  Thanks!

That's a drive error (reported from the drive and nothing to do with the software)

3 / 11 / 05      L-EC UNCORRECTABLE ERROR

Generally that's a bad sector on the original disc that cannot be copied (it may glitch momentarily in playback and you don't notice it, but it renders the disc useless for copying

The ATAPI error code you're getting from your drive, [SK3; ASC11; ASCQ05] indicates "L-EC UNCORRECTABLE ERROR" and means basically that the drive has had a read error that the error correction systems can't fix.

You could have either a damaged sector on the master, or if it's a commercial disc it may be a deliberately engineered "bad sector" written as a means of copy protection.

You won't necessarily detect this when playing the disc as many players will just repeat the last good frame if they get a read error that can't be recovered, and skip the bad frame.

There are utilities that you can try to see if you can get all the files off that disc.  One that several people use isISOBuster.  Go to cnet.com to see what else may be able to help you.  You may be able to get some of it back but I doubt if you will get it all.

Thank you all so much!  I guess that, unless I can find another master, I can scratch that title from my catalog, as I got rid of my VHS masters a long time ago, so can't make another.

Since you've been so helpful, I was wondering whether you might have an answer to something I posted last year, to which I never received any replies.

Thanks, and have a Happy New Year!

You posted that other threrad in CinePlayer which is more of a forum for the stand alone version. You may have gotten more response here.  Did you notice the issue (if you can remember) about the same time you went to IE7?  That update and one for WMP killed EMC 7.  I'm surprised that anything works.  You can try a rollback.

Yay, finally a reply; thanks, Sknis!  It's been a long time, so it's difficult to remember exactly what happened.  I'd been using this feature for years, then one day it simply wouldn't work anymore.  I only installed IE7 (kinda forced into it, but fought it as long as I could) in June, so that couldn't be the problem.  Also, I rarely use it, as once I got used to Firefox, I liked it so much better, and I have so few problems with it, as compared to IE.  I do use IE for a couple of things I haven't been able to get FF to do so far, but other than that, it just sits there in browser purgatory, rarely used.

As for WMP, I had 9 for years, and was happy with it.  From time to time, I'd give 11 a try, but always reverted back to 9 because I couldn't figure out 11, and had no time to spend on it.  I usually keep very careful records of any changes/updates I make to anything on my computer, but because I switched it so many times an reverted back to 9 almost immediately, I stopped keeping a record of those changes.  However, I lost the sound on 9 at one point, but since I'd had a new hard drive installed at that time, I also ran into other problems that were far more important for my tech to fix, so I kind of let that slide, as there are plenty of other media players I can and do use.  At the end of December, I finally threw in the towel and spent the time needed to learn 11, at which time the sound magically reappeared.  Go figure...

As for a rollback, I wouldn't know where to begin, as I have many gigs of data, and, as I mentioned, I had a new h/d installed in 7/09, which has been problematic.  I think all the kinks have been worked out now, as I hired another tech to take a look at it a few months ago, and he was able to correct numerous problems my other tech couldn't.

Ah, well, I've been using the stills/screen cap options in other programs since that option no longer works in Sonic, so it's a moot point.  However, I really liked Sonic, and wish I could get it back.  I'm currently looking into buying new external burners, so will undoubtedly be supplied with newer software with whatever I choose (have been putting it off since I have so little time to learn new things, much as I love doing that), so I suspect you'll be seeing me on some other boards with tons of questions.  Thanks, Sknis!
