Why do people feel the need to use CD-RW and DVD-RW as large floppies with the need to format them???
When I use DVD-RW (I don't bother with CD-RW these days at all - partly because of compataility issues with CD players) I just use it as a standard DVD-R disc. If I want to reuse it I use 'Quick Erase' which only takes a few seconds.
As I said before I have only ever had one problem disc (so far) and I have been using them for a while now.
I take Mouser's point though - don't rely on a single copy though with any 'burn it yourself' media. Manufacturer's recon they will last for up to 100 years but there just isn't enough data on lifespan of the dyes yet as any aging tests depend on artificial aging which is bound to be different to real aging! Personally I think a 10 year expectation is probably reasonable as the technology won't be around much by that time anyway.
Having said that I still use some floppy discs, music cassettes and VHS videos - some of which are up to 15 years old and I very rarely find problems with them.
Anyone see the article today about TDK producing a 200Gb Blu-ray disc? Now that could solve all my backup problems - shame they will probably be more expensive than the average hard disc for the forseeable future! (
