Support exFAT volumes with NAS Synology for free

I recently acquired a new external multi-TB SSD and these types of volumes are formatted in exFAT. exFAT is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards.

Unfortunately Synology doesn’t support it by default. Here are the steps to follow to overcome this:

Adapt the following commands to your needs (armhf worked with my DS216play):

wget -P /tmp/ http://ftp.fr.debian.org/debian/pool/main/f/fuse-exfat/exfat-fuse_1.1.0-2+deb8u1_armhf.deb
dpkg -x /tmp/exfat-fuse_1.1.0-2+deb8u1_armhf.deb /tmp/exfat-fuse/
cp /tmp/exfat-fuse/sbin/mount.exfat-fuse /bin/

List all your disks to find your external disk (/dev/sdq1 for me):

fdisk -l

Now you can mount your volume:

mkdir /volume1/usb-exfat
mount.exfat-fuse /dev/sdq1 /volume1/usb-exfat -o nonempty

Play with your disk, then unmount it with:

eject -F /dev/sdq

This worked for me on my 920+ I downloaded the amd64 redistribution for x86_64:

http://ftp.de.debian.org/debian/pool/main/f/fuse-exfat/exfat-fuse_1.2.5-2_amd64.deb

Thanks for saving me $3.99… What a joke that Synology charge for this.

My only issue was that ejecting at the end failed…

umount: /volume1/usb1: target is busy
    (In some cases useful info about processes that
     use the device is found by lsof(8) or fuser(1).)
eject: unmount of `/volume1/usb1′ failed

But I’d finished copying the files, so I’m not sure why it said that.

Just want to say that as of November 2020, this worked on my DS414+ running Synology 6.2 software. Just had to download the Armhf version though.

I tried your instructions on a DS218+ and its mounting the drive and I can see the files in it but cannot write anything to the drive.
