Running ATI 8 Build 937 for quite a while with no problems. Downloaded ATI 10.0 upgrade. Installed and made recovery CD. Validated my ATI 8 backup files with ATI 10 and did a restore of some folders that I deleted previously as a test. Everything worked fine. Also did an incremental backup with ATI 10, validated and mounted 2 partitions to check. Again, all OK. Will be doing a full backup of the 5 partitions on my primary drive in a couple of days. Hope all goes well again. ATI 10.0 looks good so far. Phil B.
