I'm looking to encrypt an new external hard drive via disk utility (Mac OS Extended | Journaled Encrypted) as shown on https://www.youtube.com/watch?v=FvfrIyS1K04&frags=pl%2Cwn.
Will this drive only be able to be read on Max OS? If i need to access files through a Windows system am I out of luck?
You are out of luck accessing it on a Windows machine. The macOS Extended Journaled format is unreadable by Windows.
You can share the drive by formatting with FAT32, however, as detailed in this PCWorld web page.
