I discovered recently that unbeknown to me I have been creating many dvd's with crc errors, they play fine in dvd players but will not copy. I have tried absolutely everything and looked everywhere to try and rectify but no use. I have realised though, that both the drives I use, pioneer 106 and an external freecom, despite being +/- they only create errors with +r's and I have never had a problem with -R's, apart from a bit of skipping on the 16x but I use 4x now every time. I have used cheap and expensive plus r's and sometimes the expensive ones are okay but the cheaper ones useless. I thought this might help others to know with mysterious crc problems when it is not caused through dirt, or out of date firmware etc. I am now wondering if I purchase a one to one dvd duplicator whether I can copy dvd's that have crc errors. They say they copy the master exactly but if they read the disk first, then I dont see how they can copy a "faulty" disk. Does anyone know.
The plus r's which are the only cause of my crc problem were some cheapos named Data N from local computer shop (around 50 for 12 pounds) and the decent ones which I thought I would use for master copies (lol) were maxell that cost one pound each with a case. I dont normally go for cheap stuff but a friend had sent a disk printer and I couldnt find a surface that would take thermal printing (not the maxell as they are gold with green printing). I normally use datasafe -R. As some of the maxell are okay I dont know if they were the ones I did in the pioneer or the freecom, but I know now not to buy cheap, not to buy plus r and will not go over 4x writing.
OK, download dvd identifier from here, http://dvd.identifier.cdfreaks.com/my_site/download.php Install, & put in one of your discs, we need to see who the manufacturer is!
Thanks for taking the time with my problem. Also thanks for the download link. Surprisingly this is what I got with the plus r's, the so called cheapo disks I was very surprised to see the manufacturer is Taiyo Yuden co.ltd. and the maxell says the manufacturer is ritek. I started investigating a bit more by putting them in both drives, ie. the pioneer and the freecom external, and this is what I got Both the +r's mentioned above and also phillips dvd+rw and datasafe dvd+rw all came up fine in the freecom, but when I put those four in the pioneer (dual format also, joke) I got the following red error with all four "Error ADIP read M1 failed. Invalid field in cdb (05/24/00)" When I put a datasafe dvd-r (mitsubishi) and a printable dvd-r (Ritek) in the pioneer, it was fine and they were both okay with the freecom. The two +RW's I have been using for 18 months with the pioneer and although they are saying a fault in the dvd detector program, I have never had a crc problem with them. All along I have been blaming the freecom (after it skipped with phillips dvd-r 16X) but maybe its the pioneer all along not liking +r's. It gets worse, sometimes, like now, my liteon combo drive, the pioneer and the freecom, wont read a burned dvd even when it doesnt have crc errors on it, whereas before they used to pick up a dvd straight away so I have to (when the drives feel like it), right click on the drive to open, this always happens when using dvd shrink now even with commercial dvds. I only had this problem when I uninstalled roxio media suite 8 some weeks ago, and unfortunately it took some files it shouldnt have with it, but I managed to find a patch called cdgone and got all my drives back. It was only after this I noticed these crc errors but probably a coincidence as I hadnt tried to copy a plus r disc up until recently. As I burned one of the last +r's earlier on this afternoon in the freecom I cant tell for sure because none of the drives are working at the moment to read, even though they were earlier on when I transferred a dvd-r back to the pc to check it, but so far, none of the cheap (taiyo yuden) have ever copied back and only a few maxell +r's have but until today I cant remember which writers I used for these disks. Sorry this has gone on a bit, and thanks for your help, but I wont be buying any more +r's thats for sure.
Well, I only use +RW (The + format is more compatible than dash format) & I have 3 Pioneer 108 burners. Is your fimware for your burners up to date? You need the EXACT model No, go to the manufacturers website & get the firmware for your models. I do not like Roxio, some people have had success with it, but not many. Most prefer Nero. (Philips media sucks BTW!) The TYs you have are good media, Japan is the place you want. There are a lot of fake TYs going about, this is why the identifier prog helps! Your burn speed can effect the long term durability of your back ups, no faster than 4X is recommended. I take it you are in the UK, I get my Media from here; http://www.dvd-and-media.com/dvd+rw-media.htm I use +RWs, but will try the +Rs in the near future. Just to throw a spanner in the works!
Hi, was just about to finish one of my long boring spiels and I stupidly clicked onto where you get your discs from and lost my message. I have just spotted my maxells in spindles for 49p each!!!!!! I have been getting a lot of stuff from svp (blankdischop). Anyway, earlier on I had burned one of the TY at 4 speed with the freecom, it wouldnt read in any of the drives, I then tried one of my old 4x ridisc and that read and transferred fine. Then by a miracle I put the ty back in the freecom and it decided to open up, so started to transfer and when I got back, you guessed it, CRC, so now I know that even the freecom spits out crc disks as well. Oh for the days when there was 4x discs available, all my probs seem to have stemmed from plus r's, too fast a speed and that ruddy roxio dilemna. I used to like the old roxio disc copier and used the burning prog for mp3s as nero distorted some classical music tracks I had, but I have always used vso copytodvd for burning vobs. I know what you are saying about upgrading firmware but the freecom external unit is only a few months old and I wouldnt know how to upgrade an external unit anyway. And why after all this time would it all start going pearshaped? I used to use dvd+rw's all the time to keep as a master copy and then someone told me that using rw's all the time wears out the drive. I wonder how many burns we can expect from these writers. Anyway, will look into upgrading and see how I go. Many thanks for the dvd detector and your time.
Here is a link to Freecom, you need to select the drive that you have & download the firmware. Just 'cos the burner is new does not mean it has up to date firmware! http://www.freecom.com/firmware.asp Whoever told you using RWs causes early drive failure is talking out of their a**E! I only use them & have done hundreds of burns with no problems at all. There is a life span for drives, but they are that cheap now, it is not really an issue to replace. To check the firmware, click on start, right click my computer/properties/device manager/dvd drives. double click on the drive you want. Then click on the details tab, you will then see the model, then to the right you will see the firmware No! Dead easy! It is a pleasure helping someone through their probs!
Thanks alot for finding the freecom site. I will also have a look on the pioneer site. Anything is better than replacing drives, despite them being cheap. Real headache last time as the ide cable didnt have plugs far enough away to piggyback, so the new ide cable that did was then so short that I had to practically shut the case up (a dell!!! so you probably know what I mean) with my hand still inside trying to plug in the last bit with millimetres to spare, not to mention the wire attached to my ankle and the radiator - what a crazy image!!
I can safely assume that you are a girl & the image of you contorting could sent a chap wild with desire! Glad to be of help! Now all I can think of is some hot chick with arms & legs akimbo wrestling with a Dell! No offence taken I hope! Is the Dell covered in jelly or chocolate?
Sorry to disappoint the illusion, no girl, more like old boiler, I have a 24 year old daughter - who do you think requests all the dvd's?? The e fell off somehow at the end of my name and the 33 rhymed with the C (just in case you thought I had my daughter when I was 9. Anyway, as you suggested I got the firmware for the freecom and you were right, way out of date, version 1.40 to 3.40, but alas, I used up my last "well bred cheapo" burned fine, then tried to copy it back to harddrive and after about 1GB, b....y CRC. Anyway, I dont normally give into things, but spent hours a couple of weeks ago, trying every program immaginable even tried cd check and was all hopeless, that is why I thought last night, aah what about a dvd duplicator for the 50 or so uncopyables. I might try upgrading the other two drives now that is not so scary as I thought. Thought of chucking the computer in the river at the bottom of my road, along with me, but I think it would be less traumatic just to stick to minus r's instead. Many thanks for your help and telling me about dvd detector.
This is the thing with burning, you have to find what suits YOUR setup & stick to it. What is right for one may not necessarily suit another. I'm 40 BTW, so I am the male version of a boiler! Whatever the hell that is!
how about uninstalling, defragging than re-installing the burner programs to see if clears up problem?
I have uninstalled the programs and I defrag, disk cleanup and adware scan every few days. Yep, I think that's right stick to the devil you know (-r) but I am vexed about the crc disks but they play okay, so instead of giving a copy, maybe I will have to rent the faulty ones out (only kidding of course, I'd never do anything illegal!!!) Maybe it's an old broiler, not boiler (tough old chicken as opposed to a chick) Something really weird going on with the site and my email address, as all the previous notifications today (yesterday actually looking at the clock) were coming through on hotmail which has never happened before but this last one came via ntl which used to be the case.
