Unmount USB Device correct


at my pi2 i want to unmount my usb device safe.
But when i write

sudo umount /dev/sda1

i tells me

unmount: command not found

so how do i unmount a usb device with ssh correctly ?


sudo sync && sudo umount /dev/sda1 is the correct way

If you look at the error you will see you typed unmount instead of umount

oh thx, how stupid :joy:

and how do i mount it again safe ?

It will mount automatically when you plug it back in.
