Suddenly an image file is corrupt. Any chance of repair/recovery?

So I’ve tried comparing a few images I’ve taken recently and this happened.

I was in the Library Module comparing two images (X|Y Icon) and this happened on one of my shots. I’ve checked and my GPU Acceleration is turned off (had that be a problem). I’ve also removed the Smart Preview and rebuilt it, with no success.

I’ve also checked using a RAW viewer that the image was corrupt. Is there anyway I can recover the image? The JPEG is at least intact.

UPDATE: Re-importing fixes it initially then it reverts to that state.

UPDATE2: I’ve compared it against my backup, the md5 and crc32 hashes are identical and the file size are the same.

UPDATE3: Importing it in a fresh catalog fails and exporting it generates the same result.

UPDATE4: Tested it with different RAW tool and it fails. Exiftool suggests all info is intact at least. I’ve removed the image off of my SD card so I don’t have the original unfortunately.

UPDATE5: My other backup works and the hash check is different from the first backup. This solves my problem and makes for a simple answer of just use an older backup. That being said are there tool or techniques to recover corrupt images?
