Black horizontal bands showing on raw files - Cloud upload corrupting raw files?

[Nicolas Boutmy]

Hi, 

Not sure what is going on here but I'm getting pretty worried with my files...

I shot 2 weeks of holidays on one SD card. 

I was offloading the files everyday on my iPad pro.

I synced all the files when I got back (about a 1000 raws). 

At this point, no issues in Lightroom CC (on my iPad), files were still ok. 

I opened Lightroom Classic to start downloading the files back my for local back up and some files started showing weird black band across them.

  

Now when I reopen lightroom on my iPad, some of the bands are showing up (when they didn't before).

I checked some of the original files from SD card and they are find. 

Looks like the uploading process has corrupted some of my files.

Any idea what's going on here?

Here's the original file from the SD Card when I open it in Camera Raw...

This is a corrupted file. Go back to your originals and copy (not move) the originals to overwrite the corrupted files.

Thanks for the quick answer dj. I orginally uploaded the files through Lightroom CC so should I proceed differently? Like deleting in lightroom CC and reuploading?

If you still have the original, you can re-upload that, or you can just copy (not move) the original to your Lightroom Classic somehow without uploading. There are many approaches here, and since I don't have your hardware, you will just have to try things and see what works.

I reuploaded the raw files directly in my NAS drive folders. Worked perfect! Thanks
