Problem: Can't mount exFAT HDD

Can't mount exFAT HDD
Hi

Software
XBian version: 1.0 (knockout) (kernel: Linux 4.4.6+)
XBMC/Kodi version: 16.0 Git:2016-03-11-a3eb4fa
Overclock settings: I didn't overclock it

Hardware
Device type and model: Raspberry Pi 3
Power supply rating: 1,8 Amp
SD card size and make/type: 16 GB
Network (Ethernet or wireless): Ethernet
Connected devices (TV, USB, network storage, ...): Monitor, keyboard

Log files
Link to logfile(s):

Problem description:
I formatted my HDD to exFAT, since it seems to be the best system if you want compatibility and good performance torrenting in linux.

I have installed too the AutoFS package.

But when I plug in the USB, nothing happens (no sda in media using the "df" command, no files in Kodi).
Although on my PC it works fine (not a problem with the cable).

Any other needed information, let me know.

How to reproduce:
An exFAT pendrive is not mounted either.
Same FAT32 formatted pendrive is mounted perfectly.

RE: Can't mount exFAT HDD
No too sure why you'd want exFAT but I guess you want compatibility between Windoze and Linux.

It's more than likely the drivers are not installed (They should be)

Try
Terminal
sudo apt-get -s install exfat-utils exfat-fuse exfat-utils

It should say something along the lines of already newest version.

Now check "dmesg" and see if the drive is recognised ditto "lsusb". If so,

Terminal
# sudo mkdir /media/Tempdir
sudo mount /dev/sdxx (Possibly sda1) -h exfat /media/Tempdir

If that works, then it's not automounting (Not too sure if that's a bug or a limitation). For now, you'll need to enter it into fstab to be able to use it, or try another FS - NTFS or EXT4

RE: Can't mount exFAT HDD
Seems exFAT also requirere fuse. So why not using NTFS?

How many users are using exFAT? FAT sounds for me like a very very antiquated and STONE OLD file system, I never would use this FS.

How many users are using exFAT? FAT sounds for me like a very very antiquated and STONE OLD file system, I never would use this FS.

FAT is obsolete, agree. It doesn't allow files over 4 GB.
exFAT is newer than FAT and FAT32; it allows any size.
exFAT is compatible between Windows, MAC and Linux (writable).

Plus, it seems it is better for intensive writing than NTFS, e.g. using transmission (I am a heavy torrent user):
Quote:[...]
exFAT does not have as much of the operational overhead of NTFS as it lacks many features that add complexity (and therefore processing time and disk latency) to the filesystems.
[...]
However, exFAT should be a true competitor to NTFS on systems with limited processing power and memory. NTFS on flash memory has been known to be inefficient for quite some time. exFAT’s smaller footprint/overhead makes it ideal for this purpose.
http://superuser.com/questions/257646/why-should-i-use-exfat-over-ntfs-on-removable-media

Quote:[...]
exFAT can be used where the NTFS file system is not a feasible solution (due to data structure overhead), yet the file size limit of the standard FAT32 file system is unacceptable.
exFAT has been adopted by the SD Card Association as the default file system for SDXC cards larger than 32 GiB.
[...]
A FUSE-based implementation named fuse-exfat, or exfat-fuse, with read/write support is available for FreeBSD and multiple Linux distributions. A kernel implementation has also been released, written by Samsung. It was initially released on GitHub unintentionally, and later released officially by Samsung in compliance with the GPL. None of the solutions can become an official part of Linux due to the patent encumbered status of the exFAT filesystem.
https://en.wikipedia.org/wiki/ExFAT
Plus, I read this in other raspberry pi forums:
Quote:i would use exfat, NTFS driver in linux is reverse engineered.. aka made of guess work i would not trust it.. read is fine but writing a lot like torrent would do is not recommended at least not by me!

Quote:Ok, I did some tests using rsync between ext4, NTFS and exFAT. Main conclusion: Om y system (OE 3.0.3) NTFS is the slowest, and exFAT is on par with ext4 regarding speed (not data integrity, of course).

The tests are done over a wired home network. My desktop runs Linux Mint 13 64-bit. The external drive is a 2TB 2.5" HHD, attached to a powered USB hub.

I did three test:

Copying over ssh
NTFS reading: 1.370.936
NTFS writing: 1.001.977
exFAT reading: 1.370.936
exFAT writing: 2.098.062
ext4 reading: 1.401.288
ext4 writing: 2.169.995
Copying to / from a mounted Samba share
NTFS reading: 2.195.082
NTFS writing: 1.477.623
exFAT reading: 2.583.328
exFAT writing: 5.063.323
ext4 reading: 2.812.957
ext4 writing: 5.503.612
Copying locally on the RPi (file was copied from/to home directory)
NTFS reading: 1.168.459
NTFS writing: 3.0379.94
exFAT reading: 4.364.934
exFAT writing: 3.302.167

Terminal
FUSE exfat 1.1.0
fuse: device not found, try 'modprobe fuse' first

My eyelashes are burning Tongue

I write "modprobe fuse" and it works, but this error would do the "automount" very difficult, woudn't it?

No, please add one line to /etc/modules and put fuse there. So the file should look like this (don't forget <return> at and of the line)

Code:
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

uinput
fuse

RE: Can't mount exFAT HDD
Thank you.

Not sure what is happening. First I read with sudo nano /etc/modules as you show, but I couldn't save (no writing permission). Now I just see an empty file when I send sudo nano /etc/modules



edit: Kodi doesn't even start. I messed with something badly.
edit 2: Trying a fresh install.

RE: Can't mount exFAT HDD
I added "modprobe fuse" since the "fuse" command seems to not work. Anyway, it is not working either:
Terminal
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

uinput
modprobe fuse
After reboot:
Terminal

xbian@xbian ~ $ sudo mount /dev/sda1 /media/Tempdir
FUSE exfat 1.1.0
fuse: device not found, try 'modprobe fuse' first

Anyway, I can't write through SAMBA on the exFAT partition, so I'll try to work out the "modeprobe fuse", the auto-mounting and the writing permissions problems in the next step.

I added this
Terminal
UUID=xxxF-BBA5 /media/montaje-notfake /dev/sda1 /media/usbdrive exfat rw,async,umask=0 0 0
to fstab.

Still
Terminal
sudo mount -a
FUSE exfat 1.1.0
fuse: device not found, try 'modprobe fuse' first

I give up. I'll try ext4.

"modprobe fuse" in files modules is wrong, only "fuse"

good decision Big Grin

Formatted into ext4.
Now it is SAMBA denying the writing access (from the PC and I tested from the mobile too)

With NTFS it worked the other day ¬¬


And... TRANSMISSION is haveing too access problems.

It seems that when I downloaded the incompleted files to the SDCard there was not this problem. When I've tried to download everything to the HDD, problem arises:
