Since my internal drive is impacted with very little free drive space, I'm encountering expected system performance. As a solution, I'm transferring the bulk of my primary photo and sidecar image storage to an external RAID. After transferring the files via Finder, I added the new external drive and imported the contents into Lightroom. When the import concluded, I was presented with an error dialog titled "The files appear to be unsupported or damaged", with a listed of the files.

I'm confident I'm not the only one that's experienced this issue before, so I'm asking if anyone has had success with NEF file remediation and what tools you may have used to offer that chance of success.
