I have an 18TB Plex external mass storage volume.
I'm having trouble formatting that as APFS. I want to copy all of my files to my other 18TB HDD and format it as HFS.
To ensure that files are written without fragmentation, what is the best method? I'm fairly certain that they are now very fragmented.
In addition to Super Duper and Carbon Copy Cloner, I also have `diskutil', `dd', and Disk Utility Restore.
Information about which of these tools will write the files un-fragmented is scarce.
