Getting prints ready for an exhibition and decided to look back through some Italy images from last year. Copies are sitting on two separate hard drives. To my shock and amazement, the files on both drives are heavily damaged - same jpeg maroon artifacts on the same images. Files are DNGs and last time I checked, all were fine. Guessing that they were damaged prior to backup on both drives.
I thankfully (and luckily) had a spare copy of this entire shoot sitting on one of the two drives in question under a different label and I have since copied it to another two drives. All files seem fine on this copy. I'm trying not to freak out here as I'm worried that two of my backup drives have been somehow corrupted. I've checked a few other shoots on those drives and they seem fine but I'm trying to figure out what went wrong, where was the screw up?
Better yet, what should I do know. Switch out both drives and move the data off of them? Looking for help and advice here as to what to do.
An example of the damaged file appears here:http://www.jcgamble.com/images/damagedtest.jpg
Please take a look and give me some thoughts and answers.
