this hard drive that I need to mount is on a windows machine, in a different town.
What would be the best approach for this?
I would like it in fstab if possible, and a little bit of encryption would be nice too.
when you say mount it...
you could use CIFS (or SAMBA) to share it on the remote windows computer and mount it (even via your fstab if you like) on the linux box.
A quick VPN tunnel in the middle should offer you a level of encryption.
Its probably worth clarifying your question a little. What are you trying to do with the drive once its 'mounted'?
