    According to friends working in data storage research, a much better medium than dye-based DVDs/CDs are rewritables. They use phase change media, which supposedly is much more stable in the long run. Alas, they are not that cheap ...

    yes, i hv read somewhere tat RWs do not use dye and hence do not hv those problems like the dvd&cd-Rs...

    Thanks for posting this link. I tried it and it works perfect for quickly backing up your data.

    If u backup ur stuff to DVD/CD, pls do so on media from different manufacturers -- to avoid situation where they have quality problem in a single batch.

    Read this for more on disc lifespans:

    http://reviews.cnet.com/5208-10149-0...11&tag=nl.e497

    and people who are thinking of using CD or DVD RWs to backup, read the last paragraph of the main answer...

    to have bullet proof protection, you would just have to combine RAID 1 backup of files on 2 seperate HDDs, store each HDD in different physical locations that are climatically controlled, backup the files also in DVDRs, and then rebackup files every time a new disc storage medium is introduced for greater safety and futureproof-ness...

    RWs have never been recommended for archival storage. Rs are more stable but tape drives would be one way to go a little further.

    I foudn some claims on the web that rewritables would not last very long, but nothing that would substantiate this claim (or the opposite). But I would expect better stability from rewritables. The phase change layer is an inorganic metallic alloy, whereas dyes are organic molecules that are chemically not very stable and require little activation energy (e.g. exposure to sunlight) to bleach them. (Has anyone ever thought of taking a photo by exposing CDR media in a camera?)

    oh dear - this has got me worried! Time I started doing a bit more than bunging them all onto one external HD!
