Hi I simply OPEN every important original image (or other file) on the burned disk to make sure its good. I lost some Bryce animations that I was using for a music video that way. Ran the verification- all seemed fine. Except the files were corrupt ON the CD. Then in a bit of irony, my hard drive failed when I was burning a second copy. ALSO treat CDR's as if they are DELICATE- they ARE more fragile than commercial cd's! I have had LOTS of trouble with ORB disks (from different lots, purchased over a period of 1 year, and 2 different ORB drives. On the other hand my 2 gig Jazz drive has been trouble free- and I have filed up 6 disks with NO losses. Admittedly, 2 bad drives and 5 bad cartridges is NOT a large sampling from a statistical standpoint. But I am not investing any more to buy a 3rd ORB drive... Eric Walters
