Error copying files

Recently, my hard disk is giving me problems and hence to prevent any damage or data loss, I have tried to copy all my files to an alternative hard disk.
I used the xcopy /h /e d:
However, halfway thru i got some access violation error.
Then I tried using the windows copy and paste. All I want to do is copy the entire hard disk to my other hard disk, but i get this error “There has been a sharing violation. The source or destination files may be in use.” or something like that.

Can someone please help me by telling me how to copy an entire hard-disk.

thank you
