However, there is a trick to access your Mac-formatted drive on Windows 10 and not many people know how it’s done. A lot of people think that in situations like this, formatting the hard drive is the only option but they don’t do that because they can’t afford to lose the data. Usually, Windows 10 only detects the hard drives that have NTFS (Windows file system) and FAT32/exFAT file system and because of that Hard drives which are formatted using Linux and macOS are undetectable. Your Windows 10 PC can’t access any External Hard Drives that are formatted in macOS because of the HFS+ file system. If you are having problems in connecting your macOS formatted hard drive with your Windows 10 system there are chances that it’s happening because of its file system.
