While the data from them is all one my disks so the CDs don't matter, last I checked my first Photo CDs were still readable. I haven't yet had an optical disk that passed verification fail later, that I've noticed (I do write one-shot disks that I don't keep or test, so who knows? Those tend to be on the cheap blanks, whereas I use gold archival for the ones intended for archiving.) I also hooked up a 5.25" drive to read some old floppy disks 5 years ago now, and found the disk I really wanted to read (Windows font pack) was not still readable at least with that drive. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
