I'm borrowing a Seagate external backup drive from a friend to backup my files while I partition my linux laptop. The external drive already contains several (macOS) backups made by Seagate software. However, it seems linux is not supported by the backup software.
So, my question is: Can I just make a new folder on the external drive, and copy my files into it as backup, without corrupting the existing backups?
My gut says no problem, but I don't want to trash my friend's files ... And my backup is just temporary for the partitioning.
