Is this burn okay ? Graph inside

[BlizzardUK]

Just fitted replacement equipment in my Bravo SE as it wasn't working before, just checking if you think this graph is okay for a DVD burn at 16x and verify (via USB 2). Thanks

It looks good to me. No weird drops in drive speed and a smooth curve so yes, it looks good for now. 

We could get a better idea of the quality of a burn with a scan of the disc using either DVDInfoPro, nero disc speed, or KProbe with a LiteOn drive. 

Feel free to provide a scan if you can, and we can check it out.

You basically need a burner that can do decent scans with stuff like KProbe to give you a pretty good ball park figure on overall burn quality. for example here is a scan of a random disc I had (see attached picture which is quality media (Taiyo Yuden DVD-R 8x (TYG02))). as that was a disc I scanned pretty much 10 years after initial burn and it still looks good. the 'blue' is generally not as important as the 'red' ones. but from what I heard over the years anything around a single 3 spike or so or less is considered pretty great burn quality and you can see here that nothing is higher than 2. even the 'blue' stuff in my scan here is pretty strong overall. I forgot the exact spec on the blue ones but I want to say up-to about 280 (the lower the better) would be within spec.

a while ago I got some DVD discs which did not like my burners (I returned the discs shortly after burning a small amount) and those I was actually getting actual disc read failure as I kept the disc scan to give me a rough reference point of when the scan becomes so bad it actually causes the burner to fail to read the data, which is the case on this scan with the high red colored spike. you can even see the 'blue' stuff looks so-so at best.

these basically give you a pretty good ball park figure on a quality burn and one that actually had read failure after burning. I do have some others that are sort of suspect at times even though they still technically work and are readable with no obvious problems. like one I am looking at a moment ago shows peak PI (blue color) of 674, which I am not happy with, but the PIF (red color) topped out at 9 spike (which is MUCH better than the scan with KProbe I posted here where I had actual read failure with a 76 spike with a fair amount in the 10-20+ range) but vast majority of the entire scan was 4-6 max. so basically if the disc has no read issues early on in the read, it's probably safe at the end the day.

but all of the DVD's I still have unburned will be in the ball park of the 'good' scan here since that batch I got where you see the bad scan here I returned and what was messed up is the one that was bad (like actual disc read failure) was normally quality discs as you can see from media code (Verbatim MCC etc).

p.s. but with that said, even without doing a KProbe disc quality scan, just copying data from the disc back to hard drive through file manager (or similar to what you did in your scan in the first post of this topic) might give you some rough indication (not as accurate as the KProbe stuff though) of whether the disc is currently so-so or not as if it slows during reading of the disc that 'may' indicate potential issues even though it still technically works. but even here, if the disc does not degrade much in 10-20 years, it might hold at it's current rate a long time. so ultimately you will have no real problems with the disc. I just prefer to have a good initial burn quality because I theorize 'if' the burned disc degrade at a slow and fairly consistent rate it will buy you that much more time before the disc fails to read in a random DVD reader/burner vs one that might already be so-so right from the start.
