Unreliable DVD burning - can't verify disks

I'm having trouble getting a DVD to burn reliably. I have an Asus DRW-24B3ST, which is a recent replacement for an LG Electronics GH24NS90 which also gave me problems, which itself was a replacement for another LG DVD burner that gave me problems. I've been burning DVDs of both video (wedding slide shows) and jpeg files, with verify turned on. Virtually none of the DVDs burn with no errors.

Note: in the past two months (as I said above) I've tried:
- An Asus DRW-24B3ST
- An LG Electronics GH24NS90
- An older LG unit

In the past day I've written:
- Two taiyo yuiden TY03 disks at 8X speed, they both had a couple of verify errors
- one taiyo yuiden TY03 disk at 16X speed, that had a dozen errors
- one new Verbatim DVD ordered new today, it had two errors

Since I've tried different drives and media the only thing left is my PC. The PC works fine, I doubt that's the problem, it'd be hard to cause a single bit error. It's a self built i7 2600K with a bunch of SSDs and drives.

I suspect video DVDs will survive a few errors fine, but when the error's inside a jpeg file it doesn't work so well - the jpeg is obviously corrupt when looking at it in Photoshop. In Irfanview it looked fine.

I thought DVDs were a mature, reliable technology. Should I be able to get a DVD to burn and verify easily, or am I asking too much? Does anyone else use the verify option?

When you get that many coasters the burner is in need of being replaced and yes i always verify although years ago i never felt the need. I had the same issue with one of my DRW-24B1ST's so i just replaced it for $20 it lasted me 4 years with not a hiccup. Over time anything can happen and burners are made much more cheaply then hard drives which usually die much sooner.

Even if this puppy dies in 3-4 years it's cheap enough to keep a spare on hand and it's been rated as consumers choice year after year on Newegg.

I have a brand new version, updated version of that DVD burner isoMorphic, and I've had two other LG burners do exactly the same thing in the past month. Three separate DVD burners, two types of DVD media. That's more than just bad luck!

Can you try a different SATA port and a different plug off the PSU with no other devices?

If you have a slave drive on the same SATA port disconnect it and see if there may be a problem there. If not the next step might be to run memtest or you can pull sticks and swap leaving one at a time. There are only so many things that it could actually be. I really think the drive is the culprit and testing it with another computer is the easiest way to know for sure. Also be sure the drive that it uses for cache has plenty of space.

I don't have any spare SATA ports - I have 2 SSDs, 3 HDDs, one DVD, plus an eSata add in card for my eSata drives. No slaves involved, may be other things on the same power cable. Still, it shouldn't make that much difference really should it?

Your suggestion is about all I could think of too, I didn't do it because I thought it so unlikely that it'd be a problem. Two single bit/byte errors on a DVD doesn't sound like a SATA problem to me... but stranger things have happened.

Sata port 1 and 2 should share same channel as do 3 and 4 etc..

It would be difficult to get the DVD onto its own channel. I could manage it if I thought it was a likely solution, but I think it's grasping at straws. I appreciate the thought and ideas though.

Disconnect one of the extra SSD drives in your machine and plug that into the DVD.

Isolation is the only way to begin diagnosis.

I might try that this weekend. The place I bought it from said it's unusual to get three faulty units in a row, but they're happy to replace it.

You can also slow the write speed down to get more good disc's if you have a faulty burner.

I've been trying at 4X and 16X. There are more errors at 16X, but there are still errors at 4X.

Replacement ordered - #4.

If possible, grab a SATA->USB adapter and hook it up to another machine. If good, hook that up to this PC. If good it's something with the SATA connection/motherboard​/power supply. If not good then something's wrong with the machine (CPU/RAM/power supply/etc.).

For some reason I'm suspicious about the PSU.

Good idea HY, I think I have a USB to SATA kit aronud here somewhere I could try that on.

The PSU is new, computer's stable, none of the SSDs or HDDs have problems.

Do you think it might be the DVD burning *software* doesn't play nice with your machine for whatever reasons?

Good thinking. I'm using Imgburn which is free/open source. The DVD drive came with nero but it's a half terabyte install so I didn't bother. Do you have a better suggestion?
