I have a macbook air. But my external HD is not showing up on my utilities or disk utilities. When I use the external HD to other windows PC, it it recognised there and can use it with ease. Is there any way that my macbook air can recognize my external HD?
What file system is the drive using? If it's formatted in NTFS you need to reformat it to a different file system such as exFAT so that your MacBook can read it. Just make sure to backup your data first as reformatting will erase all your data. Good luck.
