External Hard Drive won't mount properly

When attempting to mount an external hard drive it appears to succeed, but doesn't work. When attempting to access it I get: "Transport endpoint is not connected".

The journalctl says it get immediately unmounted. Here is the output:

Despite the journalctl saying that disk was unmounted, it is still listed in mount at the bottom. Here is the output of 'mount' in case it is relevant:

I was hoping somebody could shed some insight into what is causing this and how to fix it?

Correct me if I'm wrong, but doesn't this only apply to people who use mhddfs? I don't use this method to mount my drive.

Re: External Hard Drive won't mount properly

Parts of this apply to every FUSE filesystem.

It seems that ntfs-3g crashes or does something weird. Try:

ntfs-3g /dev/whatever /mnt/wherever -o debug,no_detach

Re: External Hard Drive won't mount properly

When running it with:

ntfs-3g /dev/sdb1 /media/mediadrive -o debug,no_detach

I get the following output:

FUSE library version: 2.9.4
nullpath_ok: 0
nopath: 0
utime_omit_ok: 0
Version 2015.3.14 external FUSE 29
Mounted /dev/sdb1 (Read-Write, label "", NTFS 3.1)
Cmdline options: debug,no_detach
Mount options: allow_other,nonempty,relatime,fsname=/dev/sdb1,blkdev,blksize=4096
Ownership and permissions disabled, configuration type 7
fuse: reading device: Operation not permitted
Unmounting /dev/sdb1 ()

I couldn't figure out what caused this by just googling around.

Re: External Hard Drive won't mount properly

fuse: reading device: Operation not permitted

Normally only root can mount disks. Try using some DE for mounting or add an fstab line with the "users" option (and maybe "noauto" if it's a removable disk).

EDIT:
Or maybe not. I guess the "users" way is what you tried to do and that's why you are allowed to mount in /media even though your ntfs-3g process still isn't allowed to read the block device.

I'm not sure how to deal with this. Use DE facilities if you are using some DE (they will spawn a root ntfs-3g process on your behalf) or maybe add an udev rule which gives you access to this particular HDD?

Re: External Hard Drive won't mount properly

I've always mount it with "sudo mount", or "sudo ntfs-3g", or . It outright fails without the sudo. I've also tried to mount from the root user, and it still fails. It could be a bug, but I'm not sure.

Re: External Hard Drive won't mount properly

So you are getting EPERM as root? Check if the block device file is readable/writable by anyone at all, maybe run strace to see what's the exact syscall that fails. Something is weird.
