is just a corrupt FAT partition. Have you tried:
-
Booting from one of the Manjaro live ISOs burnt to a USB stick
OR
moving your external USB HDD to another Manjaro computer. -
Executing:
dosfsck -w -r -l -v -t /dev/XdYn
where:
X
,Y
andn
denominate the corrupted FAT partition-w
means write to disk immediately.-r
means to do disk check interactively-l
means to list the filenames processed.-v
means verbose mode. Generates slightly more output.-t
means mark unreadable clusters as bad.
If you want to be sure not to lose any data, create an image of your HD first. (in this case: I would make the image on another computer)
