CD longevity
I've googled CD longevity and found a lot of stuff but nothing I would
hang my hat on. Does anyone here know of recent studies on burned CD longevity? Should I be asking in another newsgroup? Thanks Henry |

When Kodak was making discs, they claimed double the life - 200 years. 200 years, right. I have few golden Kodak CD-Rs containing RAR-arcives etc. 5 years ago there weren't any problems, but if I try to extract files from the archives now, I get CRC-errors here and there. I have stored the discs in room-temperature protected from the sun etc. and the surface looks like 100% scratch-free also. And people seem to have this strange opinion that these very same golden Kodaks were the best media available that time. Have they tried to read the contents of the discs lately? ;-) |

I've had a similar situation in which more than a few of the Kodak gold CDs I recorded a few years back are rife with C2 errors. I managed to discover and copy the data before the errors became unrecoverable. It's just as well they're not made any more... Rick. -+--- http://www.alienshore.com/seeking/ |

Nero has a test module that will show what errors there are on a disk. |

Verbatim Datalife Plus burned in 1997 with 2x Omniwriter26A(Ricoh).The ones I have tested are error free.This is the only type media I have ever used. |
