Since TV is only TV, the only data of any real (irreplacable) value on these drives are family photos. These will be burned to DVD this weekend. 3 - 5 years is a hell of a lot better than "oh shit!"
Here is some partially relevant information from National Institute of Standards and Technology: Whole article is at < http://www.itl.nist.gov/iad/894.05/docs/StabilityStudy.pdf > Excerpt below: - - - - - - While there are a number of factors that may contribute to the stability of the CD-R and DVD-R media, dye type is generally considered one of the more important ones. Based on the test results for CD-R media, this expectation appears to hold true, even with mixed results for the dye types. Samples containing phthalocyanine performed better than other dye types. In particular, phthalocyanine combined with a gold-silver alloy as a reflective layer was consistently more stable than all other types of CD-R media. Discs using azo dye as the data layer had less stability in light exposure and temperature/humidity stress testing. Media using cyanine dye performed well when exposed to light but had problems when under temperature/humidity stress conditions. - - - - - - They also say that it's not easy to determine dye type from the outside package. I saw some "long-life" gold CD-R media at Fry's a few days ago. I wasn't looking for recordable DVDs so I didn't see any. carl -- carl lowenstein marine physical lab u.c. san diego [EMAIL PROTECTED] -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
