8TB External Drive - eXFat - Unable to mount / access

[eliminatrix]

Hi All,

I have a raspberry pi 4 model B 4GB RAM with the latest version of Raspbian and the latest patches and updates.
Following this guide:

https://pimylifeup.com/raspberry-pi-exfat/

I have added exfat support to Raspbian. I tested this with a 256G exfat USB drive but I'm now trying to connect an external 8TB drive and Raspbian won't access it or mount it. I'm pretty new to the Raspberry Pi, so any help would be great!

Thanks!

are you sure 120% that the 8TB drive's format is exFAT?

with the questionable drive attached can you post the output of:

Code: Select all

sudo lsblk -f

and

Code: Select all

sudo blkid

if you dont like to post it, just tell so....

so its confirmed that on your external HDD that it is indeed formatted to eXFAT

have you installed eXFAT support?
if not install it via:

Code: Select all

sudo apt install exfat-fuse exfat-utils

or you may want to format* your drive to:
*CAUTION: formatting the external HDD will destroy all data on that drive.

NTFS:
if you want to transfer files directly from a w$ desktop or laptop (if connected to those systems)
slow performance on linux system.

EXT4:
native support for linux system,
better performance than NTFS or eXFAT,
not natively supported in w$ system (you'll need to install drivers on that w$ system)

on my NAS, the drives are formatted to EXT4 to take advantage of the better performance.
and I transfer files to and from the NAS via network.

for your reference I attach file transfer graphs NTFS vs EXT4 formatted NAS drives.

Added: to mount your drive to the NAS you'll need
UUID of drive
taken from output of sudo blkid (if you format the drive the UUID will change from what it is now)

mount point
(ex. /mnt/exHDD)

the drive format
(exfat, ntfs, ext4, etc)

then edit /etc/fstab and add the following

Code: Select all

UUID=<UUID of the drive>   <mount point>   <drive format>   defaults,noatime,nofail  0  1

then you'll need to change permissions and ownership on that drive
am assuming user pi:

Code: Select all

sudo chmod -R 777 /mnt/exHDD
sudo chown -R pi:pi /mnt/exHDD
