Erwin_Br Posted August 20, 2003 Share Posted August 20, 2003 A Dutch PC magazine has tested several CD-R's. They burned data on them, put them in their original jewel cases and stored them in a closed (dark) closet. After 20 months they came up with the following results: 10 percent of the CD-R's lost pieces of data and some of them weren't readable at all. The rest of their CD-R's caused small reading problems, but they were still able to access all of the data. It appears that CD-R's made in Japan are the better ones, because their production processes live up to more strict requirements. CD-R's from Taiwan or China are performing very poorly. 20 months is not a very long time. I'm wondering what happens to these CD-R's after 30 or 40 months. I don't even keep my CD-R's in a closed cabinet! I've not experienced any reading errors with my old CD-R's thus far, although I'm not sure how old my oldest CD would be. However, the CD-R's I'm using in my car's cd-player already give up after 6 months probably because they are exposed to heat/cold/moist. --Erwin Link to comment Share on other sites More sharing options...
fov Posted August 20, 2003 Share Posted August 20, 2003 hmm. i have a few CD-Rs that are about that old. haven't noticed any problems with them... yet. if it were really an issue, i think we would have heard people complaining about it before now. but, a controlled study is hard to argue with. i definitely agree that some CD-Rs are better than others. i used to work for a software startup and we distributed our demo software to potential customers on CDs. it was sometimes my job to make the CDs. i once bought a stack of Office Depot brand because they were cheaper... what a mistake that was! one in every three or four had to be tossed out because it was unusable (and that was brand new!) -emily Link to comment Share on other sites More sharing options...
Burge Posted August 20, 2003 Share Posted August 20, 2003 I've got burnt CDs eons older than 20 months that work fine. What a load of baloney. Link to comment Share on other sites More sharing options...
Mattsius Posted August 21, 2003 Share Posted August 21, 2003 I have four to five years old CD-R:s which still work fine, so that study is pure bull. Link to comment Share on other sites More sharing options...
pleto4_ryan Posted August 21, 2003 Share Posted August 21, 2003 well....i believe the cd-r's life is something that is not controlled. Many thinks...like temperatures, sun, crashes etc can harm the cd far before its day of death And of course there is also the companies quality of the CD-Rs.. What i would like to know is.... In the experiment...have they used cd-rs of the same company? Link to comment Share on other sites More sharing options...
