First off ive burned probably 300 dvds, so i know what im doing. I have an _NEC DVD_RW ND-2500A. I've never had any problems burning. I had the big lebowski backed up on dvd+rw, and it took about 20 trys to rip the image onto my hard drive. First time i ever ran into that, i kept getting I/O device errors. It finally went though and i burned several copies onto DVD-R media. All copies play perfectly on my dvd player and my PS2. I just backed up star wars also onto a DVD-R, which plays fine on my ps2 and dvd player. I tried to back up some files onto DVD-R but the data verification failed, so i tried again. Its burning the files successfully, but data verification is failing. So I have 4 copies of the big lebowski, 1 copy of star wars, and 2 data dvds of the same data which my pc will not read. How the hell is my burner able to burn a perfect DVD onto this dvd-r media....but then it cannot read it? I keep getting the error: "Windows cannot read from this disk. The disk might be corrupt, or it could be using a format not compatable with windows" The dvd-r media im using was the cheapest dvd-r media on www.shop4tech.com, which is what i always order and ive yet to have problems. Is this just bad media? Is my laser dead?(neither my DVD+/-RW drive nor my DVD ROM drive will read these dvds. It burns fine, just cant read in either) If its the media should I send it back? The movies seem to burn fine, but if i ever need another copy i wont be able to because my dvd drives cant read the disc, so ill have to use the original, which defeats the whole purpose of making back ups. I tried uninstalling both of the dvd drive, but no dice. still doesnt work.
It does sound like your media. I am unsure of the exact name brand of that dvd-r media,but majority of brands of media can be made by numerous manufacturers and their quality will vary.The lower quality media can give you more errors,making them harder to read and re-rip.Even with changing spindles and different quality batches. That quality will vary.Reduce that burn speed as slow as you can. It might be very crappy,considering both your nec and dvd-rom drives can't read them.Probably many errors. Try some better media,like maxell/tdk/fuji/verbatim data life plus/ritek/or fuji in the dash format. You may even want to flirt with the plus format-but avoid the tdk +4x and +8x. There are 2 different manufacturers on those plus tdks and their quality will vary considerably between them. I look on the wrappers when these brands are on sale,by finding the ones with Made in Japan,they are definetely higher quality. Here's a handy,free version of dvdinfopro. It can tell you those manufacturers of your discs and try checking out some of your older and newer backups and see if the manufacturers ID changes. It also has a couple of scanning tests to locate burn errors.It's a very handy program and get it here: http://www.dvdinfopro.com If you have nero,nero speed test can also scan for errors and mfg ID codes. A buddy just gave me a couple of staple's +8x discs made by moser bauer and I will scan these for errors with dvdinfopro pie/pif scan test.They burned ok at 2.4x,but I don't trust them.
Well the ones I usually buy are around $23 to $25 for a 100 spindle. They are from shop4tech.com and are called "sonic" brand. They worked beautifully up until this order. I thought everyone was always bullshitting about the brands of media because I always bought the cheapest brand (which was always sonic) off that site and never had a problem. I emailed customer service to see if its a compatibilty issue or if its a bunk batch. Hopefully they will just replace them. If not I supposed i'll be going to another source and buying more dvds. Where do you guys buy your media? $23 for 100 is a good price which is why I always ordered from there. I've never seen any physical store in my area come even close to matching that price.
http://meritline.com/taiyo-yuden-4x-dvd-r-media-silver-lacquer.html These are taiyo yuden go1's and they are working great. Rima.com is also a reputatable dealer for these yuden go1's: http://www.rima.com/Merchant2/merch...Code=R&Product_Code=1769-100&Category_Code=4X
I did the firmware update and its working. Its loading the dvds I already burned, but its not really reading them still. I burned some new dvds though and its reading them just fine, so the firmware fixed up the writing and reading. Its also burning at 8x, and its only 4x media.
