Re: Unison sync not working

Dear Toivo
Thank you for suggesting on /mnt/128GB SSD. After I change it in my
work prf, the sync is back in working order.

root =3D /home/jq/Downloads
root =3D /mnt/128GB SSD  <------- This as you suggest

Now another issues, hope you can assist also. I got 2 120GB (1
Kingston and 1 Western) SSD install in external HDD enclosure. Both
are 120GB. I created another prf under kingston-ext.prf

root =3D /mnt/128GB SSD < ------ This is internal SSD in the Dell
root =3D /mnt/120GBEXTSSD <------ This is external SSD in the enclosure

Now when run the unison kingston-ext.prf command in terminal, an error
as below appear


[BGN] Copying yong lee JGD1958 bill 14406.png from /mnt/128GB SSD to

When I go to my File Explorer and right click on 120GBEXTSSD, go to
Properties, under Permission only show "Access Files", the filesystem
for the 120GBEXT SSD is under FAT. May I know how to solve it?

Thank
JQ
