Other Can't use FUSE mounts

Hi, I can mount the card successfully, but when I ls it, it fails. The card reads fine on another machine, and I could properly mount it a few months ago on FreeBSD 11.2. Here's the terminal log:

Code:

# mount.exfat /dev/da0s1 /mnt
FUSE exfat 1.2.8
WARN: '/dev/da0s1' is write-protected, mounting read-only.
# cd /mnt
# ls

If I toggle the write protection notch it still fails.

Looking for help. Thanks!
 
I would consider trying Vermaden's automount utility. This is not the same as the base system's automount and you would probably have to build the ports sysutils/exfat-utils and sysutils/fusefs-exfat unless you can find them in the package repositories-- I can't find them in my "lastest" repository for 12.0. I've used Vermaden's automount before; version 1.5.8 is available as a package. 1.5.8 works on FreeBSD-11.2, but doesn't work with FreeBSD-12.0, and so, for 12.0, it has to be upgraded to 1.6.0 or 1.6.1 using the github link. I haven't tried it on an exfat sdcard but I assume it would most likely work, after installing 1.6.0 or 1.6.1 plus exfat-utils and fusefs-exfat.

Or you might be able to use the two exfat ports with whatever else you might be using. When I run pkg search exfat I get nothing from either the "latest" or the "quarterly" repositories for i386 machine architecture so it seems one would have to build them from ports.
 
Thank you guys, but your suggestions don't resolve the issue.

I'm not using the automounter. I already have fusefs-exfat installed and running, and that's what I'm using to mount the card above. I'm not sure how configuring the automounter to call fuse instead of calling fuse manually would solve the issue.

It was mounted in read-only because I toggled the the write-protection notch. If I turn the notch off then it mounts fine without the "read-only" message but still doesn't work (everything past that line is still the same.

The sdcard is written by a camera which uses exfat only, so recommending other filesystems is not a solution. And it's definitely not corrupt. I don't have a Windows box, but a linux one reads the entire thing and writes it perfectly.
 
Hi, so I've been using testdisk to read exfat cards for a while, therefore this wasn't a critical issue so far. Yet this issue persists, so I gave another shot at trying to fix it.

As it appears the problem is not with the card, nor with exfat. There's something wrong with FUSE in general. I used the sample code from https://man.openbsd.org/fuse_main.3 to compile a simple utility to test fuse... and guess what? It fails in the same way:

Code: 
# fuse-test -o debug /mnt

By now it's 12.1-RELEASE, and needless to say I have fuse_load="YES" in /boot/loader.conf and fusefs_enable="YES" in /etc/rc.conf.
