Hi there, I have a 2TB Seagate external hard drive that I purchased and used with various PCs at work. It turned into read-only when I connected it to Mac this morning. I was able to open the drive and view files on the drive. But if I attempted to copy a file from my Mac to the drive, nothing happened. Something might be obviously not right with the storage drive. If you have any clue to fix read-only external hard drive on Mac, please tell me. Thanks!
