I tried reformatting as ext4 and added this line into /etc/fstab
/dev/sda1 /media/USBSSD ext4 defaults 0 2
and then remounted as ext4 and set permissions of /media/USBSSD to 777, and that got me quite a way along the road.
Now, I've set up my samba user and have been able to make a connection to the share from a windows machine and have successfully written a file into the share.
I'm trying to do the same thing now from a (different) desktop linux machine (i.e. not the one that has the disk attached) and although I've had a go at mounting it, I dont have write permisisons.
From the desktop linux machine (linux mint, latest version) I copied an example from here (http://www.cyberciti.biz/tips/how-to...der-linux.html
) and ran
sudo mount.cifs //nasmachine/share -o user=usr,pass=pwd,dom=WORKGROUP ~/Nas
I can see the contents, I just can't write to it.
I also tried
sudo mount -t ext4 //nasmachine/share -o username=usr,password=pwd ~/Nas
mount: special device //nasmachine/share does not exist
but that didnt work.
Btw, regarding needing to be root to change the permissions above, I think I was running chmod through sudo
