The purpose of this post is to get advice from the drive experts here. It is NOT an Acronis TI issue, which for me works great. I had two instances of validation failing in about 6 months. Today I got rid of three old images, roughly 14 gig each, made a backup which validated ok. Then I ran chkdsk on this external drive (2 hours!) which revealed, maybe, the cause of those few failures. Subsequent revalidation of 3 backups (2 images, 1 differential) validated ok. But it worries me a bit. Does anything in the below record strike the experts as some sort of serious trouble? I'd think 192 bad sectors doesn't sound too good (zero such on the C system drive), nor the 'crosslinking'. Suggestions for the future, please.
