I may be totally wrong on this, static MAY corrupt data but it’s not likely to cause a drive to fail. Comments on that welcome though! Your data should be safe but to retrieve is more difficult. Is the drive self powered via USB or is it a mains powered drive. One of my self powered clicks and takes ages to mount but plug it into the mains and it is fine. Update (07/19/2020): So, Rags, sorry to rub salt in the wound but I’m guessing when you consolidated all the pics onto one drive you dumped them off the other two before making the second backup ☹️ Remember if you have valuable data on only one drive, it’s not a backup. I work with 2 clones of my Macs as they are currently and anything archived is stored on 3 separate Drives in different locations. I hope you can retrieve everything. You could try to run retrieval software on the 2 drives that had the pics duplicated on, that would be a cheaper option as long as you haven’t overwritten them of course.
