Mount permissions problems

Question

when I tried to mount and other ssd in my elementary os I had get this problem: All the files with no permission, seems like they are being mounted as root, but why?

I trid to follow this another topic: NAS share mount permission problems , but without success.

this is my fstab file:

  GNU nano 4.8                                                                                                      etc/fstab                                                                                                                
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system>  <mount point>  <type>  <options>  <dump>  <pass>

Answer 1

Can't comment (weird Stack rules...) so here is a question:

why do you have backward slash in your fstab line?:

gid=1000,uid=1000,nounix,nofail,x-gvfs-show,\040 0 0
