I download the files from the Lacie external hard drive to the desktop and then upload to the seagate external...but I cant seem to drop it into the seagate hard drive. I am able to brings things from my seagate to the desktop but I need to upload the files from the Lacie to my seagate. Quicktime movies are on the Lacie and I need to get those movie clips to my seagate so I can use my PC to edit. Help please.
