This has been driving me nuts. In my work PC, I have a Lite-On LH-20A1P DVD Burner. Some discs it just flat out refuses to rip. DVD Shrink and DVD HD Decrypter both return CRC errors.

The first couple of times, I wrote it off as scratched discs. More recently I have unwrapped DVDs from their packaging and put them in and get the same result. Any disc that I cannot rip I can take and put in any one of our HP laptops and rip with no problems whatsoever.

I also used to have a Lite-On burner in my PC at home (It got replaced with a Samsung SATA model when I built the new PC, haven't had any issues with it yet) and it did the same thing at times. Do Lite-On drives just suck or what? I tried updating the firmware on the work drive, go to Lite-On's site, select my model, download the firmware and it gives a message saying "No compatible drive found. This firmware is for LH-20A1P drives" then directly below it has a list of installed drives and what's in that list? "LH-20A1P KL0N" so I looked it up, and KL0N is the firmware revision, I couldn't find a site stating as much, but I assume that to mean that it already has the latest firmware available.

So what gives, what can I do to fix this issue? The drive is fairly new... about 4-5 months old I think.

If what T suggests isn't the problem then it's 1 of 2 things. The burning software you are using is out of date (the internal drive/driver database) or the drive is fubar.

It's not the burns that fail, it's reading and ripping to hard disk that isn't working. I can burn DVDs all day long. I rip with either DVD Fab HD decrypter, or DVD Shrink and then burn with DVD Decrypter. I use these same programs on my drive at the house, a brand spanking new Samsung SATA unit and they work fine. While the drive at work is an older IDE Lite-On.

And the laptops I was using to test whether it was a disc issue or not are fairly new as well. Pretty sure it isn't software issue.

And pretty sure it isn't hardware issue either. As I might burn 100 movies in a row before I get one that throws the CRC error during a rip. It seems to me it's basically kind of the same thing some drives have with types of media. You know, you find those bargain deals on media and then try to burn to it and get a bunch of coasters. Same thing, but in reverse. It's like it doesn't want to read certain types of media.

These discs that it won't rip, I can open up windows explorer and see the contents of the disc. I can play the movie back. I did actually let one movie play all the way through and it stuttered and skipped quite a bit in sections, like it was scratched, but the surface was pristine.

And there's the fact that I had a Lite-On drive in the old computer that had similar issues, but was not the same model. Also have a friend that has an external Lite-On USB drive, and his does it from time to time as well. And now that I think about it, any disk that his wouldn't rip, mine wouldn't either, but then I could stick it in one of the HP laptops at the office and it would rip just fine.

sounds like a tracking error... or maybe a read laser alignment/power error. on the latter, even pristine looking discs can have weak bits that better drives will see no problem and it might confuse. but yeah... sounds more like the weak sector/laser problem.

While converting my 600+ CD Collection to MP3s....it failed to read correctly after around 400 discs. I would still burn fine, but, no more reading of audio files.

What's a replacement drive going to cost? $25?
