vaporware

Here is a new spin on "vaporware". I have discovered 2 cdr copies
that are no longer playable. One is a year old the other 4 years. I
use the best media and factories, when choosing blank media and
store all of my media in optimal temp away from UV light.

I have not gone through all of my CDRs to determind if others are
unreadable but this is a disturbing turn of events.

After recording on DAT for 13 years, I have had little to no
problems. Luckly, I have the master DAT for the 2 lost CDRs. But, if
I didn't, "vaporware"!

This is not good. Has anyone else had this problem? If so, I believe
as consumers we are being duped and have a legitament beef with the
industry.

Also, it may be a "real" reason for us not to leave behind magnetic
media. I know this was the complaint when people were jumping from
analog to digital and the catastrophic loss with DAT but at least
DAT last a lot longer than CDR's. At least that is what my
experience has been so far. I have DAT tapes that are 13 years old
and play back with 0 errors.

Other's feedback is appreciated. However, please remember that all my
media is optimally choosen and stored. I've been at this game for
too long to make a "rookie" mistake.

I recently took a LINUX course and CDR, CD-RW longevity was mentioned as an issue for data backup media. Apparently this technology has not been around long enough demonstrate reliability and long life. The judgement is still out. BTW, tape backup was considered the fastest and most reliable.

"For preservation, said Gibson, the Library of Congress - the largest information collector in the world – depends on half- track, quarter inch analog audio tape for backing up its over three million sound recordings."

Namely, all digital media are not considered for long term archival purposes by anyone serious about longevity. Analog master tapes 50 years old play as well today as the day they were recorded. DAT or CD-R are short term storage solutions.

did you use? I've used the Kodak Gold (no longer made) specifically because of the accelerated aging tests done by Kodak on the media showing a 30 year life. I haven't seen the tests on the Kodak silver/gold yet. I am not aware of other manufacturers who publish aging data. Have you seen any data from other manufacturers from accelerated aging tests? I'm asking as at some point, I will run out of my stash of Kodak Gold disks. I use them mainly to store photo images, and at this point, even 30 years doesn't come close to film longevity.

T.Y. is my main brand. Again, I use the best media and storage possible.

This problem is well spread and not limited to brand type.

Warning, "do not expect to use CDR as a media form". As for analog tape, well, there are many reports of shredding and baking to save the tape for one last pass."

Hmm. You must be lucky with your DAT tape. At least with regards to computer backups. occasionally we'll encounter trouble with older media (+5 years).
