Will the command rm -rf / remove the contents of external hard drives?

Question

linux

There is such a terrible command that deletes all system files: rm -rf /
I know from my own experience that in addition to the contents of the hard disk, all the contents of inserted flash drives, sd cards, etc. are also deleted.
Actually the question is whether this command will delete the contents of:
1. hard drives connected via usb
2. network drives or partitions connected via local network

Answer 1

Delete if they are mounted, i.e. if the data is located somewhere at /something-there, it will naturally delete it.
Unless, of course, you have the right to do so.

Answer 2

1. Only if they are mounted
2. Only if they are mounted as local folders (smb will not affect)
In reality, there has long been a patch that protects against rm -rf /

Answer 3

Delete ... I remember on Radio-T I listened to an instructive story how one pr thus erased client data along with backups, because during the execution of the command, volumes with backups were also mounted on the system.
By the way, this is an instructive story

Answer 4

No, it won't delete. It won't delete anything at all.
rm: it is dangerous to operate recursively on '/'
rm: use --no-preserve-root to override this failsafe
