So, long story short. My HDD is acting strange. It's an internal HDD in an external enclosure. Basically, Some of my files I can't even see on the drive anymore. I can open a few files, and others seem corrupted. Opening them in a hex editor shows that data has shifted. I have bits of movies in image files, bits of image files in movies, it's just a scrambled mess. I've ran chkdsk, file/partition recovery software, I've even tried Spinrite but that freaks out as the drive is 1 TB. SMART is fine, chkdsk is fine, I don't know what to do... Is there anything I can do to repair or recover some of these files? It's pretty much a full terabyte of data, and losing all of it would be unfavourable to say the least. tl;dr, help.
