Hi
I have bought a new 4tb my book external hard drive
I have a 3tb my book essential and wanted to put alll my folders and files on my new drive
So connected both drives to my desktop computer running windows 7 64 bit
I then went to my essentila drive and CUT all the files
Then went to my new drive and pasted then into it
It took all night to do paste in 2.5 tb to my new drive
I switched off and dissconect my new Drive and left in my essentila drive BUT I can see it in device drive and listed all okay also i can see it in drivers and printers
BUT I can not see any thing on my drive or in explorer it is not listed
What have I done wrong please
