Data Missing after reformat on other harddrives

so I reformatted my main harddrive and reinstalled windows and after doing that several rar’s and a few movies no longer work corrupt data or something. How do I fix this? The hard drives that are having problems are a western digital and a seagate. Thanks for the help
Answer #1
Corrupted files sounds pretty difficult. Normally if they were lost you could try soem recover programs, from my sig, but if they are corrupted I don’t think they can help. You can try some anyway.
Answer #2
trying em now will let you know if it works
