Welcome to the Manjaro community.
Note that paths/mountpoints should not contain any spaces.
Linux permissions do not apply to exfat formatted partitions.
You might try checking the partitions concerned using chkdsk. This should be performed from within a Windows environment.
As a new forum user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit:
The Update Announcements should be checked frequently for important update related information.
These announcements contain a Known Issues and Solutions section and should generally be checked before posting a request for support.
Output of the following command formatted according to forum requirements (see links above) may be useful for those wishing to help:
inxi --admin --verbosity=8 --filter --no-host --width
Be prepared to provide more information and outputs from other commands when asked.
Regards.
