Steps to repair invalid dng

[RP2A03]

Hi,

When I validated the files in my library I had one dng listed as invalid. It wasn't always so.

It seems to be fine visually. Is it enough to click 'Update dng preview and metadata' which stops it from showing as invalid, or should I reconvert it in case there is some underlying corruption in the file. This was only one file out of >10,000 and I know it was never shown as invalid before.

Thanks

I would try converting it to DNG again from the original.
