Update: I tried to manually create a (hard) link : The results follow :

carthik at milan:/media/work-usb/carthik/rsnapshot/weekly.0/localhost/etc$ ln
adduser.conf/media/work-usb/carthik/rsnapshot/weekly.1/localhost/etc/adduser.conf
ln: creating hard link
`/media/work-usb/carthik/rsnapshot/weekly.1/localhost/etc/adduser.conf' to
`adduser.conf': Operation not permitted

So why can't I create links on the external USB hdd ?

Thank you,
Carthik.
