surely 1 million times asked, but nothing explicite found by search, sorry...
the short question: is here a tutorial about external USB drives, how to setup and prepare and what ever?
the long question, if not:
how can I use an external USB HD for data save/load?
when do I have to plug it to the Pi (before start or ar any time, like for Windows, being auto-detected)?
If not autodetected: what di I have to prepare to get access to the drive (FAT32) and it's folders and files using the file manager?
will it also work for NTFS formatted drives or just for FAT?
