Mount USB disk

Problem:
You need to use a USB disk with your Raspberry PI.

Solution:
Raspberry PI OS will recognize automatically your USB disk but you need to follow the next configuration steps to use it correctly.

1.- Check your current OS partitions.
sudo fdisk -l
2.- Create a shared forlder.
 sudo mkdir /media/MyUSB
 sudo chmod 777 /media/MyUSB

2.- Setup fstab file, this file store your mount configuration
sudo nano /etc/fstab
 Add one line to configure your USB disk, somethink like:
/dev/stda       /media/MyUSB    vfat    rw  0   0
/dev/stda    path to the USB sick
/media/MyUSB mount path where files are stored
vfat         FAT32 format



3.- Confirm an apply changes.
sudo mount -a
4.- Check current partition.
sudo df
Additional info:
To Remove the disk in save mode:
umount /dev/stda
Notes:
- Remember to change shared folder authorizations to 777, if not you will not be able to share it trough NFS or similar. 

Hardware:
In my test I use a 128 USB flash disk  from Philips and it works really well to manage file between the raspberry system. 

Remember that this will work not only with flash disk, also with external  USB hard disks.
