I have a hard disk drive with data that i want to back up onto another hard disk drive. I tried just copy and it won't let me paste it in the new drive. I have also tried to drag the files across and they won't go across. Does anyone know how to do this?

I have an external hard disk drive with data that I want to back up onto another extrnal hard disk drive. I have tried to copy and paste but this wont give me a paste option. I have also tried to click and drag but it wont let me either. I have reformatted the external hard drive to accept both mac and pc files and this did not make any difference. Can anyone help me with this?

How did you reformat the drive? If you formatted it as NTFS, your Mac will not be able to write files to it unless you use a small application such as Paragon's.
Please reply as to how you formatted the drive.
