[Samba] samba question

[brandon berumen]

i have a media player which is the one at this link: 
http://www.argosy.tw/product-detial.php?prod_id=154 they say i can use samba 
with this. my question is this, i already have a substantial amount of data 
stored on this hdd. if i were to install samba now would i lose my data? do i 
need to backup data elsewhere and install samba then migrate the data back after 
install or can i just install samba now without fear of losing any data?
