Brand new TrueImage 10 on an HP computer with "LightScribe" combo drive. The Mobo has I believe an nVidia chipset with SATA storage interconnect. Athlon dual-core CPU, running Vista Home Premium edition. I use only TDK and Verbatim DVD+R media. Doing my first full backup, which takes 4 disks. Doing it with "verify" turned on. (Been burned by that before - useless backups back in the old tape days) As it asks for each disk for the verify pass an alert say an "Error occurred when opening the archive" and this was because "Archive is invalid or its type is unsupported". I click OK each time and it keeps on verifying. (The time estimate on the verify progress dialog is quite pessimistic by the way. It is actually going at about the same speed as writing.) At the end it says "The operation was completed successfully." Do I have a valid backup or not? I have been thru this twice, once with TDK and once with Verbatim.
