Repair File on RAID 6 Volume (lemmy.world)

I have a RAID 6 volume with data protection on my DS1621+. A video file seems to have become corrupt - it worked in Plex a few months ago but now it won’t play at all. I’ve tried in VLC, the built-in DSM video player - nothing seems to work. No other files appear to be corrupt, all drives show as Healthy.

Is it possible to repair the file, and if so how would I do that? My research seems to only find results where an entire volume is corrupt. In this case I’d like to just recover a single file.

RAID is not a technology designed to manage backups... it is designed to either support speed or reliability. If you overwrite a good file with a bad one, then you have a very fast or reliable copy of a bad file.
