Long time to burn and extract DVD data disc
I have an old PC with AMD Duron 1.20Ghz, 480MB DDR RAM, 18GB HDD Seagate 4MB cache PCChips motherboard M810DLU Windows XP Pro 32bit my burner is a Samsung SH-S182F 2MB buffer and burn a data disc of 2.61 GB using the program Imgburn at 4x burning for two hours and to extract all the contents of the disc to the PC is 8 hours
after burning the disc did a scan disk using nero DiscSpeed and no error found is this normal? why is that? can someone explain me? my HDD manufacturer Seagate Hard disk name U Series X 20014 Figure 3.5 " Capacity after formatted 20 GB discs 1 Recording Surfaces 1 Physical Dimensions 147.0 x 101.9 x 19.99 mm Weight 455 g Rotational latency 5:55 ms Rotational Speed 5400 RPM Maximum internal transfer coefficient 445 Mbit / s Average Seek Time 12.7 ms interface Ultra-ATA/100 Transfer Rate Buffer to host 100 MB / s Buffer Size 2 MB |
Either:
A. The drive is dying. B. The disc never burned well from the start. A disc scan may be okay, but that's only one test. The TFT and jitter matter too. |
1 analyzed the disc with Nero DiscSpeed and no bad sector, can also copy all the files from the disc to the PC without any problems but it takes a long 8 hours to copy 2.61 GB and then copy all the files to the PC do an analysis with 7-Zip archives and in no error, the recording is OK?
2 which is TFT and jitter? 3 this long time to burn and copy may be because of my setup too old? burning recorder driver and HDD has only 2MB cache buffer |
TFT and jitter is explained here: http://www.digitalfaq.com/forum/medi...r-burning.html
Read that. :book: You need a certain drive make/model to do the jitter/PO/PIE/PIF scans. And there's an art to reading that. Lots of people get it wrong. It's not hard data,but one that must be interpreted along with the media in use, and the drive in use. TFT is basic, like the disc scan, though both are still influenced by the drive some. Complex stuff. I'd just do that TFT and scan disc. |
In my free Nero DiscSpeed 12 has no option to turn no TFT, jitter, / PO / PIE / PIF, TRT
My recorder is a samsung sh-s182f I did a scan with nero DiscSpeed and it seems the problem is the dvd burner drive access time is high |
TFT = "benchmark"
Not all drive can use the two disc quality scans. (PO, PIF, PIE, etc) And if you don't understand them fully, or have somebody that can help guide you with what you're doing (helping to interpret the results), there's no point. MyCE, formerly CDFreaks, is full of people making asinine conclusions because of poor understanding of what these tests actually mean. Don't do that. Don't be "that guy". |

The pre-MyCE days were really bad, lots of ridiculous posts. Look back at them sometime. For example, when Ritek was supposedly "good" and scanned well, people were almost having orgasms over how supposedly great the discs were. They were terrible, of course, and time has proven this. Ritek had a serious quality issue in the pre-oxonol days, and even slight degradation in the in-house dye media would cause it to be difficult to read in most drives, as it was so out of spec. RITEKG01 to RITEKG05 dye, all of them. Lots of myths came out of that forum, such as "bad batch" -- a reference to a spindle, not the 100,000 to 1,000,000 (or more!) that actually makes a "batch" of media. That silliness was how they often explained the unreliable manufacturing from CMC, in an attempt to defend it as a good disc. In other words "CMC is great, save a bad batch." Total malarkey from morons. Most people knew nothing of media, yet posted weird theories as facts anyway. It's really not any different from the 9/11 conspiracy sites, which are almost entirely caused from lack of scientific understanding. I don't visit MyCE often, but I believe it's more sensible these days. However, all the old BS can still be found via search. |

It's a shame that their dye could deteriorate in just a few weeks, but nobody could know that beforhand. Quote:

I've been burning DVD-R since 2001, and had experience with RITEKG01 and RITEKG02. Before that, I'd been burning CD-R since either 1995 or 1996, and had come across a few Ritek discs sometime in the 90s. It was rarer in the USA back then. The older discs simply were not good, and I had no reason to think that had changed.
The hype surrounding the G03 and first half of the G04 era was blown way out of proportion, with many even proclaiming it to be the best disc ever. If you remember back, it was the era of PVC (Pioneer), Japanese TDK, Japanese Maxell, and Singapore/Japan MCC. Even Taiyo Yuden media was not as good yet! (TYG01 was not great.) To suggest that Taiwanese DVD-R was superior was ridiculous. (Note: Taiwan is fine now, but not back then.) The Ritek dye aged regardless of whether it was burned. The data doesn't "disappear", but is simply hard to read on most drives. BTC is one of the only ones that can reliably read them, and it was famous for reading problem discs. (BTC has been gone for years now, of course.) That's another myth from CDFreaks -- "disappearing data". If you really look at all the aspects of the Ritek G03/G04 scans -- not just the common ones -- there were telltale signs. If nothing else, those discs were more variable, whereas other quality media had more expected values. People were always "surprised" that it tested that good/bad. My main gripe was how the old CDFreaks site was always a knee-jerk kind of place, without any degree of patience and long-term analysis. It was mostly caveman logic that prevailed, with instant conclusions that lacked merit. Add in a few hecklers/trolls -- like the obese 20-year-old anime nerd "Dolphinius_Rex" that hadn't even yet finished college, much less had any professional media experience (yet pretended he did) -- and that was CDFreaks.com back in the day. It was disappointing. I don't think it (now MyCE) ever really recovered from their heyday. Part of that was due to the invasion of trolls, and the unfriendly environment. I could say the same about Afterdawn and Doom9. The former has spammer issues, the latter had moderator/admin issues. From about 2004-2007, several video sites were simply NOT very inviting or friendly to newbies. As such, newbies never came. When the trolls left, the sites had little left in the way of regular members. Again, very disappointing. It's one reason why I spent all my time here and at VideoHelp over the years. I'm a media/video professional, and simply don't have time or patience for that BS. I've had my new laptop since May 2012. MyCE was still blocked by NoScript. So I've not logged in for at least 15 months now. But I just did, and yes I still have an account there. If the rabble is gone, I may go back. Right now I'm in the middle of a personal media case study. It spans 2001-2013 media, at least 1,000 different discs. I think you'll be interested! It's something I plan to publish around the end of the year -- at least start to -- and it's going to be quite a few pages long. It's going to be interesting, as I'm testing discs that have been burned for 10+ years now, and for some I have before/after (same discs scanned in 2003, 2007, 2010, etc, if I can find them all). I can PM you when I get close to done. :) |

There were some kinds of DVDR dye known for rapid deterioration - the most infamous ones were the 4x and 8x dyes ("Dye 41" and "Dye 82") from Interaxia AG (Swiss supplier of DVDR dyes, stampers and process know-how). I do not know if you have any experience with VDSPSAB/VDSPMSAB media, they were not widely available in North America. Interaxia's dyes were used by almost all European DVDR manufacturers and by tens of mostly small producers in Hong Kong, China and southeast Asia. 99% of DVDRs that were made using Interaxia's dye went completely unreadable within 3 months, regardless of actual manufacturer, initial burn quality, storage conditions, etc. The scandal fully broke in summer of 2004, forcing Interaxia AG to going bankrupt (with an enormous debt) and driving about a dozen of their customers off market. And, of course, leaving tens of millions of DVDRs with unrecoverable data. Quote:

In most cases, the drive has issues, and it's why somebody can't read a disc. The drives age terribly, and are either weak or even fully dead in 2-3 years. Ironically, discs will far outlive drives. Even when the drive is good for burning, many are crap for reading, even the home-favorite scanning drives. My BenQ is still work great to scan discs, but the Pioneer DVR-111 is a better reader on problem discs. That was always my gripe -- too much blaming discs, and not enough analyzing drives. Just blind assumptions, and that's not science. Quote:
In fact, one of my Interaxia discs (possibly another dye) just became unreadable since November 2012 and the re-scan in May 2013. The disc was problematic last year, and had to be read with ISO Puzzle with many retries. Now nothing can recover it. That discs was burned around 2004 or so, and is almost a decade old. I've had some Ritek "die" in the past year, but the discs were always really bad value-wise (scans). I didn't scan then as often, but they became unreadable in the past 2 years. The discs were also from 2006 or earlier. In my experience, even bad discs tend to last at least 5 years. And bad discs was less than 1% of all media. Meaning the initial burn quality is still the most important, because of the % of coasters from manufacturer to manufacturer (anywhere from 1% to 50% or worse). It, along with others, is in the media case study. And the above statement is likely my conclusion. Trivia: More than anything else, reading disc ISOs give problems because of corrupt IFO/BUP, which many falsely blame on media. I've had at least 40 discs with issues because of this. Annoying! (Not my author work. I know better.) |

Somewhere I've got some Interaxia AG discs (VDPSMAB, or something like that), but will have to look for either the discs or the scan images. I used to have more, but tossed them back around 2005, and re-burned to better MXLRG02 discs at the time. That was one of the best, easiest, discs to get back then. Even the local drug store carried them on sale! I don't think I tossed/replaced them all. My personal DVD collection is more or less set now, as I'm mostly making ISO files to stream, or using the higher 15Mb/s Blu-ray specs for 720x480 video. What I want to do is scan each disc for PIE/PIF/PO/jitter/TFT values. I've tested many for periodic checks in the past, but this is the first time I'm scanning them all. There's thousands of them, going back a decade. And most discs are older, not newer. I plan to find the now+past screen caps from scans, too, if I can locate them all. |
You can tell if burning was successful without errors by doing a surface analysis with Nero DiscSpeed? after burning the disc philips dvd + R 16x cmc mag m01 taking 2 ˝ hours I opened Nero DiscSpeed tab and clicked analyze disk and analyzed the surface of the disk and analyzed the disk read and no damaged bad sector found I looked disc at the bottom and no staining dye
this means that the burning was successful without errors? |
Yes and no. I'll answer this post in two parts. Here's part 1:
There's essentially 3 typical discs tests: - surface scanning, which you did - transfer rate tests (TRT) -- sometimes called a "transfer test" (TFT) - the advanced jitter, PIF, PIE, PO testing You can pass one, yet fail others. To have a good disc, it needs to pass all 3, and with good values. The surface scan usually means you can read a disc right now, and thus extract data if needed. But that can change. The way to estimate these changes is by analyzing the other two tests, especially the jitter and PIE (parity inner failures). I'll get to part 2 in a week or so, which is mostly some sample images. Very busy right now. I know you want answer now, but this will take some time to explain. I can do something quick to aid in explaining. But if you don't get it right away, I'm not explaining it again. It's not that I'm mean, but because I'm putting together something huge, which should explain it in-depth for novices. So you'll have to wait for that, if needed. It's going to take a few months. |
please help lordsmurf
1 then as I do these other tests ? does not have these options in Nero DiscSpeed 2 My drive is a Samsung SH- S182F 2007 3 I have 3 discs recorded in the same way taking two hours to write , I must do the test with 3 disks or can take the test with only one disk to be the same thing in the other ? are kept so wanted to take the test only one disk 4 I'm worried about losing my files in dvd that I have not done the other tests, My files will be deleted automatically and not be able to read the disc in the future because I did not do the other tests |

I can't scan it right now. But it's "ONID 4x 0001" and "0213". When I went to scan it again -- I could read it! So I dumped the ISO. The disc isn't even half full, which is why it was not re-burned and tossed in the past. Most bad discs have past 2-3GB, so anything smaller was assumed to be fine long-term. I've got a spindle of problem discs. Thus far, all but this one are RITEKG03, G04 and G05 media that have reading failures. I tried them with 9 drives each, and set them aside when it failed all 9 times. Curiously, it was usually RITEK DVD-R and TY DVD-R (Taiyo Yuden) -- non-fake TYG02 especially -- that consistently give errors, and another drive is required. Pioneer read best, while all others (LiteOn, BenQ, LG, Samsung) have varying degrees of errors. Most Ritek and TY require a Pioneer 111, which is one of the best Pioneer readers ever made (and thankfully, I have 3!) But I digress... The oldest DVD-R is from 2001, and is some of the first produced by Pioneer (PVC). I'm not sure what's rarest yet. I have all sorts of goofy discs from UK and Europe. Not so much Asia. I'm maybe 50% done ripping discs. I'm setting aside odd stuff, old stuff, and problem stuff, as I want to scan those first. Then I'll do all the others (TDK, MXL, TY/YUDEN, MCC, PVC, RITEK, FUJI, etc). How rare are the LGE discs? I'd never seen any myself, and I'd looked. I have 5 unburned ones in jewel cases. I'm not sure if the was an outsourced ID, or in-house discs that quickly got discontinued. Those are from 2004, 4x discs. They had 1x and 2x too. It may have ONLY been sold by LG directly. Not sure. I could never find out much about this media, though I've not looked in at least 5 years now. |

1 I found the flap to analyze disk is translating into Inglęs ScanDisc so I did this analysis ScanDisc read all discs and no problem detected 100% good 2 jitter, PIE and PIPO errors will do I lose files on disks and never be able to use them in the future? |
For now, it's fine.
In a few years, maybe not. But by then, I'll have finished my guides, and you'll read them. ;) |
1 By tests without errors ScanDisc you said discs are Ok but I do not understand the "In a few years, maybe not"
2 jitter, PIE and PIPO errors will do I lose files on discs and never be able to use them in the future? 3 ScanDisc detects jitter, PIPO and PIE errors? if the disc has these errors they appear? PIPO does not give the option to activate |

Future. Not now. Now is fine. We'll talk about the future later. I'm busy. Your discs are not dying soon. Seriously, enough for now. I have work to do. I'm not answering any more questions. :old: |
1 I do not think you understand me, I did not ask about the quality of the disc or aging him because I know that in the future I will have to redo the backup on another disk degradation of it, what I want to know is if jitter errors, PIE , PIPO will cause the loss of files written to disc in the future and if these errors will affect the disc read future
2 ScanDisc of Nero DiscSpeed detects jitter, PIPO and PIE errors? if the disc has these errors they appear? PIPO does not give the option to activate |

if my discs are burned with errors jitter, PIE, PIPO and C1/C2 these errors will cause loss of data on the disks and dvd drive will not read the disc? these errors will cause losses in the future?
