Personally, I've got an external Terabyte hard drive for backup and nothing else.

I have perfectly fine CD-Rs written in 2004; I have no idea where they got their information.paperburn1 wrote:CD/DVD experiential life expectancy is 2 to 5 years even though published life expectancies are often cited as 10 years, 25 years, or longer http://www.archives.gov/records-mgmt/in ... a-faq.html
I suspect that your right. RW cd/dvd last the shortest and are the cheapest. R CD/DVDs last longer and the type of dye used is another large factor in lifetime. Also how you store them is a large factor. This is one area where spending a few dollars more can save a headache down the road. We have a directive not to use RW for the long term storage of data becuase of fears of degradation. The R cd/dvd handle heat and abuse much better. If you take good care of your data I am not suprised you get a good life time out of your disks. we supply data to the military and we nickname the users "edward hammmerhands"WizWom wrote:I have perfectly fine CD-Rs written in 2004; I have no idea where they got their information.paperburn1 wrote:CD/DVD experiential life expectancy is 2 to 5 years even though published life expectancies are often cited as 10 years, 25 years, or longer http://www.archives.gov/records-mgmt/in ... a-faq.html
I suspect the 2 to 5 years is a rewrite time to assure 0 bit loss; the CD data format includes Error detection and correction (24+4 in 192 byte packets).
One year at work we decorated the Xmass tree with bad disks. (shhhhh I know we are not supposed to have a tree in a federal building)ladajo wrote:So I should not hang them from my rearview mirror? Dang it. I really did like the sparkle.
