Plex – External FAT32 USB drive

So, trying to use a Linux Mint laptop and Plex for a lower power consumption server seemed a good idea, until I realised the disk in the laptop was only a few hundred gig. I opted to use my backup USB disk to serve the media. Its FAT32 and already contained hundreds of videos (as it was my backup)

I wanted it to automount, and always be connected so that Plex just sits there serving away and occasionaly updates the library with new files. My mount point is /media/plexmedia/

I used fstab to mount it. and with many different options and trials, I discovered this to be the optimum line:

UUID=DA3C-7706 /media/plexmedia/ vfat auto,users,umask=000 0 0

Explanation of the settings:


This will set every file to rw for all users and groups.


Will automatically mount the drive. Not really necessary but I like to leave it there.


Allows the disk to be mounted by any user. I don’t want root owning it, as then Plex might not be able to read/write nicely.

Finally the 0 0

The first 0 means that I don’t want the disk automatically backed up ever
The second 0 is telling fsck that I don’t want to check the device for errors.


Now, to get your UUID, you’ll need to run:

sudo blkid

Note: Its better to use the drive’s UUID – as this doesn’t change, but if you were to shuffle the order of the disks around (as in the physical USB ports) the /dev/sda labels may change.

Its important to note, that you cannot change the attributes of the files on a FAT32 disk in Linux, as they don’t have that sort of security metadata within them. The user access changes must be applied to the mount point. A lot of people forget this and is a source of confusion often.

eXfat drive not working in Windows XP?

So you got a nice 64GB USB stick, and can’t format it NTFS but want to transfer huge files on it. You probably formatted it with eXfat (Windows Vista, 7, 8, Mac)

But the ISO you downloaded is on your XP machine, you can compress it and span the 4GB limit set by FAT(32) OR, you can just install eXfat support on Windows XP using the download provided by Microsoft themselves:

And, if Microsoft ever remove it, like they are prone to doing… You can download it from here:
