Hi
I am working on a mac. I have download some photos files into an external drive and backed the, up on another drive.

I was working on the files in Lightroom then some files just disappeared. I then downloaded the photo files again as I still had them on my Compact Flash cards. Over night they disappeared again off both the external drives? I ma running the deep Scan anti virus which has not completed as yet. Am I using the right product? any suggestion as to the cause and fix for this problem. Thanks
