Safe ejecting of random USB-Drive

[magicBanan3]

Hello Folks,

I'm new in the Raspberry Pi World and need your help.
I try to eject some USB-drives of my PI with a Pythonsketch, therefore I use those Codes:

Code: Select all

sudo eject /dev/sda1

Code: Select all

sudo umount /media/pi/*

Code: Select all

sudo eject /dev/sda

In my opinion those codes are working, because after I use the code I can't find the USB-driver I my path, but after I remove a USB-drive I get the following message: "Drive was removed without ejecting. Pleas use menu to eject before removal."

So is it just a message or is my sketch not working right?

Thank you for your help!

Please avoid "sudo", it is not needed to unmount your own disk.

I just do:

Code: Select all

sync
umount /media/<user>/xxxx

The sync is probably not needed, but does no harm.

I think that's your problem. You're unmounting the device *partition* and then ejecting the entire *device*.

What do you mean with "<user>"?

Ahh alright and how do I unmount the device in the right way?
Thank you for your answer!

What do you mean with "<user>"?

It means the name of the user account. The default for Rasbian is "pi"

So in the example:

Code: Select all

umount /media/pi/*

<user> = pi

Ah okay, I tried in this way: "umount /media/pi/nameOfUsb" and it works, but I still getting the same message.
