Wd 1012 Error

Hi I am able to view files listen to music and watch videos but as soon as i try to transfer to or from my device it just hangs. I’m copying via teracopier. Thanks for any help or advice in advance

Maybe it’s a problem with Teracopy ?

Are you able to copy the files using the standard built in Windows 7,8,10 copy function ?

that’s the 1st thing to test to see if it’s software or system device problem.
