Sorry, I started another thread for this LATE last night but realized this morning that this is a better forum for it. If there is a correct way to move a thread that I don't know, I apologize in advance. The original thread started here: http://forums.afterdawn.com/thread_view.cfm/302574 As you can see, I've got over 400 G05s that burned fine, played perfectly and now, 3-6 months later have completely fallen off the earth. Any idea what caused this? Any idea of how I might salvage this situation? Here is the scan I performed on one of the discs. It displayed problems similar to all the other discs I have tested:
I could be wrong but I don't think the Pioneer drives are reliable for these type of scans. At least mine isn't.
this is the first scan i've ever done. i can't stand by the accuracy of the scan, but i can tell you that all of the g05 backups i have played fine a few months back, and won't play now. not on a standalone, not on a mac and not on a pc. dvd decrypter reports read errors constantly and won't copy them back to hdd.
Wish I knew an answer for you. I have a couple hundred of the GO5s and haven't seen problems yet. I'd say bad batch but 400 seems unlikely. How are your DVD's stored? Not using labels are you? Is this printable media?
i ruled out the "bad batch" because i bought 500 discs over many months from supermediastore.com in increments of 100. they are white printables with no labels or inkjet printing on them. they have been stored in wallet style sleeve cases for the duration. never in direct sunlight, no exposure to extreme temps, no scratching, almost always upright. the other media stored in identical fashion (imation (!), sony, and ridata G04) all play perfectly. It is only the G05s. Worst part is, the only reason i switched from the G04s was that the white tops take sharpie writing without smudging.
@plan4 i'm really sorry to hear of your misfortunes, i guess all the "buzz" going around is in fact TRUE about recent PRINTABLE RitekG05s quality control going downhill... as neodave mentioned, Pioneer drives are VERY inaccurate in terms of scanning, but nothing "tests" a disc's reliability like playback in a standalone...in your case, these discs won't even play back in a pc, let alone your standalones; so i think we can eliminate the whole "bad batch" theory on incremental purchases over the course of a few months like you've done. here is a snippet from my own thread where a good friend of mine, teflonmyk, also experienced something very similar as you and here, another trusted collegue of mine regarding the PRINTABLE RitekG05s again, member is forkndave... http://forums.afterdawn.com/thread_view.cfm/4/262544 much like neodave, i have had 500+ SUCCESSFUL backups on the Ridata RitekG05s from about 2 years ago, they still play and scan fine to this day, quality scores from a Liteon drive in the high 80s-low 90s after about 2 years. i no longer use them anymore, not because i had any issues, but because i have found THE media that works BEST FOR ME and MY OWN setup, namely Taiyo Yuden and some Verbatim in the dvd+r format~ but, also, MY successful RitekG05s were the "regular" ones, they were NOT INKJET PRINTABLE, but rather Ridata Riteks's matte/silver surface. last few months, there has been a LOT of talk about the PRINTABLE RitekG05's (8x dvd-r) being very poor in quality/reliability; often times deteriorating only months after a "successful" burn, the issues were amplified once "printed on" as well... there is not much i can suggest with your 400+ bad backups other than to TRY to re-rip them (using dvd decrypter as you have been doing) or simply using your originals and putting them onto well regarded "better" media. Taiyo Yuden or Verbatim would be my suggestion, i know this is going to COST more $$$, but if you want to preserve so many backups in your collection, i'm afraid that you might have quite a task ahead of you and the SAFEST/most RELIABLE route to take would be to "do them over" from your originals~ once again, i'm sorry to hear of such misfortunes on these PRINTABLE RitekG05s, we've discussed them on quite a few occasions recently and have basically come to the conclusion that the PRINTABLE RitekG05s are just not worth the headache/ $$ spent for them as they don't hold up as well as one would expect. redoing your backups from the originals onto Taiyo Yudens/Verbatims would give you the best bet for long term durability/playback-ability~ docTY~
the oddest thing about the playback is that if i select a chapter to test (usually one of the last chapters where the problem is accentuated) it typically plays perfectly. only when i scan around or skip to another chapter and back and play again does the picture break down and ultimately crash the player. i tried to rip one back to the hdd with dvd decrypter, but it was a nightmare of read errors. i sat with it for about an hour and managed to rip 50% of the first VOB by selecting retry over and over again. the resultant file actually played without error. i assume that dvd decrypter given enough retries could rip the dvd in its entirety, but it would take forever and require me to actually sit there and babysit it.
@plan4 in terms of you "babysitting" the re-rip process, i'm assuming you don't have the "ignore read errors" box checked/ticked off in the "I/O" tab under "settings"~ you could go into the settings portion of dvd decrypter under the "I/O" tab and tick that box off, that way, even though decrypter will AUTOMATICALLY keep going without manual interference, might save you the time to actually sit there and click thru each error to have the program continue...even though decrypter will keep trying, this naturally WILL take some time...i feel dvd decrypter is STILL a very good ripper, even on "bad discs" that you are obviously having issues with at this point. it probably would be a lot easier to re-rip to your harddrive using the originals, assuming that all these backups were done from originals to begin with but if that is not the case, then you have a very long and tiresome task ahead of you, some WILL re-rip, others will not be able to due to the deterioration...just transfer as many as you possibly can to better media, with that said, this will naturally take hours if not days to go through your large collection, i wish you the best...good luck docTy~
Ritek Printables G05, is the only Ritek disc I had problems with (x8 white full face Ritek G05 Printable) as happened to you, they lasted a few month, I managed to save them as i do regular batch scans of my disc's. Sorry to hear its happened to you, its not likely you'll get any decent results trying to salvage those disc's. To safeguard your back-ups in future I'd recommend batch scanning them. best o luck
The sad thing is about 14-18 months ago, these were considered very good quality. A lot of people recommended the Ritek Ridata so I also purchased some of these exact discs. It wasn't more than a few months later that the bad reports started coming in. Ritek's used to be considered Very high quality by a lot of people. Especially the G04's, but I bleieve in the last year they have switched their dye's and the quality has went down. I would hope that we are not saying the same thing about TY's and Verb's a year from now. Anyway's, just realizing that I am in the same boat as you plan4. I will try to weed out and find some of my G05's tonight and post some scans with Nero CD/DVD test (not that easy to find on printables). Unfortunately I just started doing these scans since my old dvd burner wouldn't do them before. My new one will and I would recommend to all newbie's to do periodic scans of of their batches of media.
hmmm..i remember in a previous thread that Brobear said that Ritek were considered better quality than MXL coded discs. Maybe he has some input that will put your mind at ease. This disc failure of Ritek is now on a similar scale to Princo. There has also been cases where Maxell non-printable GO5's have failed a few months after burning. Mine in fact. For people not wanting to use the more expensive media, ie MXL, TY and MCC and Sony then look to brands such as Gigastorage, Infodisc. Much better reliablity than Ritek rubbish. Ritek = Princo = Crap
Actually in my experience of Riteks, the G05 x8 Printable has been my only problem with the media, all the Maxell G05 (hundreds) most scan over 90 and the Ritek +R x8 have gave me my best scans of any media so far. I've got Riteks at 2 year (G04) and again they scan high. Also have had a few Verbatim, Taiyo Yuden and Maxell (mij) which have scanned well then deteriorated fast and needed to re-burn. Batch scan your DVD's, you get to find whats best for you and your setup and what last. I still use loads of Riteks (maxell)....if it works...
thanks for all the input. it honestly never occured to me that discs could burn well, then break down that quickly. it looks like the backups are all coasters. guess i'll just have to come up with a creative use for 400 bad discs. since this seems not to be a problem specific to me, perhaps a post should be made on the bad media thread so others know to shy away from the ritek G05 printables.
plan4 - I was able to find a G05 from October of 2004. Tried to scan it and it immediately went to "0". Scan was off the chart. Figured I was in the same boat as you. However I decided to test it on the pc with power dvd. It started to play with no issues. So I decided to use dvddecryptor in file mode on the dvd and it worked with no errors. You may want to try this before going back to square one. As we all know the longest part is the compression. I'll just have to file mode than burn them all. Figure a half hour per disc as opposed to 90 minutes. I'll have my son test it on a standalone tomorrow (the bad ridata).
Besides doing the ignore read errors as Doc posted, you can also lower your CRC retrys to 2 or something. The default is 20 retries and that takes forever on one error. I figure if it doesn't get it on the second try, it isnt going to get it on the 19th try either. I tried to save 200+ movies backed up on CMCs getting the very same thing. Dye Rot. I finally gave up and never did back up some of them. One movie i had decrypter working on even with the lowered retries it was still trying to rip after 6 hours of constant work with nothing else being done to the computer. The CMCs burned and scanned well at first. Then a few months later movies that worked perfectly before started skipping and all the other problems we see with bad media. By then its too late. The movies you really like the most, try the decrypter route, or get the original. Others are casulties of the DVD war.. R.I.P..
Hi plan4, Just to let you know, your not the only one, my colloction of discs have also suffered the same fate, ritek printable G05, I have about 300 of them, used with my pc and dvd hard drive recorder (tv). Some DVD's are only a few months old, fine when burnt but now are totally unreadable. I wish I had'nt stuck to the one make, I am now trying to back up any that I still can but I have lost alot of stuff I cant get back that I recorded of the tv (to keep for years?) I found this forum by doing a google on bad dvd's and found your problem was excactly the same as mine. Can I ask what disks you are using now, any recommondations from anyone? I wish you luck in your task of backing your collection, allthough no consilation, were at least not alone.
Taiyo Yuden TYG04 media. Spend some time on this board and you will find that just about everyone considers TY media the best. I just got 200 of them and so far, they are testing great.
