Why can't I add files to my Toshiba external hard drive?
I plug in my 1.5 TB Toshiba external hard drive on a mac and i can view my files, copy & paste them to my desktop. But I can not add any files to the hard drive. A "cancellation" sign appears when I try to drag and drop any type of file? I have over 1 TB of files on drive with 500 GB of free space left. I would transfer files to another device then attempt reformatting it, but i don't have the time or money to do this. Any help or suggestions? Thanks.
Is this a good question?
