SOS PLEASE.. USB3 failure for both 1 and .5 TB WDMP

As already formatting the System drive [C: With Win7] ,I just formatted the whole drive [931 GB] but the problem still occures, After sometime backing up 180GB with Paragon (I tried also simple copy paste, and also winBackup) it’s simply suddenly shut down. One more thing i did in the last time and when i think about it the one major thing i did which was around where that problem occured is to bitLocking both C: and D: drives, could it be the problem? i am afraid it’s not a software issue… coulf it be also?

Thanks
