>>109679793A friend asked me to get his old pictures from his old dvds, because he didn't possess a dvd drive anymore. None of the dvds were readable anymore. So on self burned cds, it's a thing I assume.
>>109680238Never experienced anything like it myself. Works like a charm each time. Last CD I checked was from 2009.
>>109679793Yes but irrelevant unless you're using 20 year old CDs from one of the affected batches. Modern blurays and even CDs do not suffer from this. This is like worrying about bitrot on a USB stick because CERN found a handful of instances in their petabyte scale datasets.
I have bought many used CDs this year and have some of my old ones. Only one exhibited this kind of issue. It's mostly a meme but bad pressings from specific plants can have this problem. There was a Coldcut album where it took multiple people on the torrent tracker redacted trying to rip their copies until someone got it to read perfectly. Parity data from cuetools helps with this issue.
it's an absolute meme. i have this first print MJ cd that i personally bought in 1992. it's spotless.
>>109679793sure, disk rot is real. data is all doomed, when it comes to current media.m-disk is the only example of an attempt to secure against time, a media.
>>109680482That's not a cdr bdr or whatever.Those also suffer, but less, and dependent upon conditions. Don't believe me? ok, leave it in the sun for 100 days, like on a dash. It may still play, but just look at it.in other words, they age.Try this with a gold ring. put it on your dash. Leave it for 1 million years.It may experience some loss of molecules, but it will still look pretty.
>>109679793ones you burn yourself? absolutely. decade+ territory is already danger zone. from my experience brand of discs doesn't mean much for the most part .
>>109680899>ones you burn yourself? absolutely.i have 25 yo discs i burnt myself in the musty basement.
>>109680368USB sticks lose data on 100% of the cases, tho.
>>109679793As long as you store them away from heat, humidity and sunlight, it shouldn't be a problem.>>109682344Any flash memory will lose its data if left unpowered for long enough.
>>109679793Mold love to eat the disc.
>>109679793Optical backups are good. CDs and Blurays are good. Some DVDs are okay. The godfucked organic dye discs are bad and WILL die. M-disc is untested and an upcharge for peace of mind (trust us bro) but regular HTL BD-Rs are pretty damn durable themselves.
>>109681279Sure you do.
>>109680238If they're toast it's fucked, if there is small damage there are tools to recover the rest of the data. It highly depends, CD-DAO or write-on-demand mode where you slowly fill a disc is very dodgy, burning an ISO full of files if there is damage, it might be confined to a small amount of data even within a single file.
>>109683517Not him but I had 30+ year old discs that read fine and floppies from the early '80s that do so too. It's all about storage, the older dye-based CD and DVD writable media can be erased with diffuse sunlight even.
Believing in disc rot is the same as believing things like Fiji exist. Can anyone here prove it? Anyone here has a rotten disc?No. They just trust and repeat what internet told emBit rot is the sameIt's like philosophy, metaphysical crap may not exist in our world yet faggots think they are smart discussing it
Well, you see it's OPTICAL. It also happens to be MEDIA.
>>109683789I found a rotten disc in your mom's box. Call of Booty.POW
>>109679793All my gayming ones still work. The ones i burned all fucking died. They were very old though. I think the quality of these cds/dvds is important.
>>109683817This is highly unrespectfulYou have a rotten brain
>>109683789>leave disc in sunlight under stacks of jewel cases>one focuses light on CD and makes pinprick>CD ROT!>have dye-sub media>leave it in heat OR light OR high humidity>CD ROT!CD rot is rare. It happened mainly to pressed CDs when they had a contaminated rinse cycle due to some failure in the industrial process. Burned media has a max age. Best is MAM Gold, which uses real gold! Everything else is shit except M-DISC which is even more expensive and noble.It's so rare, that you can't even calculate how often it happens randomly, it's basically "was there an error in processing" or not, or did you burn on low-life media.
>>109680238How did he store them?
>>109683823That's just like, your opinion ma'am.
>>109682974No, mold not love eat disc. Disc made of aluminum and polycarbonate. Mold love eat organic stuffs. Mold especially not love metal. Metal kill mold.
>>109683831CD rot prevalence was largely a myth to scare people away from possessing media capable of long term storage.Similarly, the NiCd memory effect was also bullshit… even the authors of the original paper which “invented” the term (which had to do with NiCds in orbital satellites) recanted it. No, we don’t want people to be able to store their own energy any more than we want them to store their own data.
>>109683778I'll buy the floppies, magnetic tape is quite resilient. I doubt the entire batch of CDs worked if stored poorly.
>>109679793it’s totally realfor some reason I never ripped my Battle Chess discand I ripped that particular 30-year-old CD like a year agocdparanoia had trouble
would survive dropping, flooding, emp's and solar flares. use something like dvdisaster with 60%+ crc or simply a rar file with extra redundancy.
>>109683947I only ever came across one example "rot" in a history of handling hundreds of them. And that was on a very cheaply made cd single from the early 90s that was foil backed and came in a cardboard sleeve.I have naxos classical music CDs from the 1980s that still play perfectly fine. I have burned verbatim cd-r and dvd-r discs from the eary 00s that all still play fine.They are stored in a dry, dark, cool place, on a spool or in their case.I think most of the "disc rot" crowd are actually scratches. Most people don't store or handle their discs properly
Has the issue of disc rot being resolved? >Yes, the industry largely resolved these systemic issues by the mid-to-late 1990s through several critical improvements in chemistry and engineering.>The primary fix was the improvement of the protective lacquer layer. Early CDs had seals that were prone to microscopic pinholes or "crazing," which allowed oxygen and moisture to reach the aluminum. Manufacturers developed more robust, chemically stable polymers that created a near-hermetic seal, effectively stopping the oxidation process that caused disc rot.>Additionally, the purity of the reflective aluminum was improved. Early manufacturing sometimes left trace impurities in the metal layer that acted as catalysts for corrosion. As the process became standardized globally, the quality control for the sputtering process (how the metal is applied to the plastic) became much tighter.>By the time the industry shifted toward mass-production and later into the era of CD-Rs, the "natural" decay seen in early 1980s pressings had become a rarity. While a modern disc can still be destroyed by a deep scratch or extreme heat, the spontaneous chemical breakdown seen in early PDO or Nimbus-era discs is essentially a solved problem in factory-pressed CDs.
