How can I make my external hard drive compatible with Mac and Windows?
“I have two computers, one running Mac operating system, another running Windows. I want to copy and transfer files between the two computers using my portable external Western Digital hard drive that is originally formatted with NTFS. I have realized that NTFS drive is fully supported on Windows computer, but read only on Mac computer. That is to say, my external hard drive is unable to work well both in Mac and Windows. Is there anyone who can tell me how to make my hard drive compatible with Mac and Windows? Thanks a lot!”
