Hi I guess the problem comes from the dmask=**0077, in which the second
zero means the owner has no right to read/write

You may try to run this and see if it works:

sudo sudo mount -o
remount,rw,uid=1000,gid=1000,shortname=mixed,utf8,dmask=0755,,showexec,flush,**uhelper=udisks
-t vfat /dev/sdb1 /media/external
