I’m trying to copy files from internal hard drive to WD My Passport Ultra 1TB drive. If a try and copy a group of files I get apparently random files failing to copy with a “0xC00D3E85 : The request is invalid because Shutdown() is called” error box displayed. If I hit retry it will suceed.
Any ideas what may be wrong?
Drive is brand new, chkdsk reveals no errors. Running Windows 8.1
Thanks in advance.
