I've only found UDF to be read-only not writable. However, using CD 
burning software, what I do is to blank a CD-RW then write to it is 
ISO9660 as though it were a CD-R rather than CD-RW. As I use it for 
backups, writing a lot at once is what I want to do. There is not the 
convenience of adding a single file to it as with UDF, but this fits my 
needs.

I would like UDF write support, but have not found any.
