File Size, CR2 Recovery
File Size, CR2 Recovery
I recently ran a large data recovery of photos on a RAID5 NAS (around 10,000 Canon CR2 RAW files), and it seems to have recovered a majority of the data, but the files are a smaller size and lower resolution (2560x1707). These are usually ~24MB, 21MP images. Is this expected? I can certainly work with 4.4MP images since I would otherwise have nothing, but I am just curious about why and if there is something I scanned incorrectly.
Re: File Size, CR2 Recovery
All depends on actual data on the RAID. Looks like you assembled the RAID and scanned it correctly.

Okay -- so if the original files were 24MB, how can a valid restored file be of different size and resolution? In my limited restoration experience I would expect this to generate a corrupt file.

Re: File Size, CR2 Recovery
I've seen cases where an embedded thumbnail inside the file caused it to think it was at the end and truncated the file sizes. Try disabling the *.jpg extension and do the scan again for just CR2 files alone. Usually, that can solve it. If not, you'd just have to create a custom file type for the CR2 format.

What extension do those files have? Maybe they're jpg rather than cr2?wani0402 wrote: ↑Wed Apr 24, 2019 9:51 amOkay -- so if the original files were 24MB, how can a valid restored file be of different size and resolution?
