I have a Macbook air and I was trying to store my files into my portable external hard drive but can't do so. I can open and copy files from my hard drive to my mac but can not copy files from my mac onto my external hard drive?
Hi, so I have a Macbook air and I was trying to backup files into my portable external hard drive but can't do so. I can open and copy files from my hard drive to my mac but can not copy files from my mac to my external hard drive. When I perform the same task on a Microsoft/Windows it works fine. Can anyone assist me with this problem please.
Thank You in advance
MacBook Air, OS X Yosemite (10.10.2)
