I drag and drop copied large number of files from one external hard drive to another
and now I want to check the integrity of the OS's copy with rclone check
rclone check /Volumes/HD1 /Volumes/HD2 seems to work fine (i.e. using paths and not remotes) but I can't find in the docs which hash it is using for the check when paths are used instead of remotes.
What is rclone check doing in this instance, and can I tell it which hash to use?
It will be the "minimum" hash common between two paths. Hash "ordering" starts with "md5 < sha1 < ...". Local paths support all hashes. So if both paths are local, it will be md5.
