<pre> Hi everybody,

we recently purchased a G4/733 Mhz CPU with what Apple likes to call the Superdrive (which is a built-in Pioneer DVR-A03). Together with Toast 5.01, it allows (in theory) the back-up of data to DVD-R media. I say "in theory" because I've already hit severe limitations of data storage with DVD-R. It seems that at this point, limitations in in the way Macintosh has implemented the UDF file system which DVD-Rs use lead to a maximum filesize limit on DVD-Rs of about 2GB. You can not use up the 4.7 GB space of DVD-R media with one single file.

Having had this sobering experience, I'd now like to get some feedback from people who have already implemented DVD-R as hardmedia storage for digital images. I know that a lot of people have been talking about migrating all their CD-Rs to DVD-R, but I haven't actually been able to find anybody yet who has been there and is willing to tell the tale. Anybody out there backing up image files on DVD-R?

If you could, I'd be especially interested in what kind of hardware & software you use, what the hit-and-miss rate of the burning process seems to be, how the bigger storage media changed your workflow, what you expect long-term reliability to be etc. As usual, any and all feedback is very much appreciated.

Thanks! Günter
