Thank you for test ... and feedback

this is wrong

Code:
/dev/sdb1 /media/universe ext4 rw,relatime,barrier=1,data=ordered 0 0

/dev/sdb1 /media/universe

don't mix media with universe


So..change sda1 to sdb1 line
put this line in fstab and do reboot
/dev/sdb1 /universe auto defaults 0 0

don't forget remove that Symlink

after reboot give this command to make sure mounted usb pin with universe
df -h

after that try plugin again ... 100% work with me ..
