Raspbian + Flash Drive + fstab

First off, you need to figure out the path of your flash drive:

[cc lang=”bash”]
fdisk -l
[/cc]

Then… edit /etc/fstab as follows:

[cc lang=”bash”]
/dev/sda1 /mnt/flash vfat rw,user,umask=0002,uid=1001,gid=121 0 0
[/cc]

Note that umask is… the “inverted” regular file mask. This represents 665 (because we’re evil). As per uid + gid, you can figure it out by means of this command:

[cc lang=”bash”]
id username
[/cc]

Update:

The best filesystem to use, if you need to maintain compatibility between the Flash Drive you’ll use with your Raspberry, and macOS, is probably ExFat. Now, problem is: Linux doesn’t really support ExFat by default.

So, we’ll need to install it, as follows:

[cc lang=”bash”]
sudo apt-get install exfat-fuse
[/cc]

In such case, your /etc/fstab file should look like this:

[cc lang=”bash”]
/dev/sda1 /mnt/flash exfat. rw,user,umask=0002,uid=1001,gid=121 0 0
[/cc]
