Sharing an external HD over the network

[ikillbears]

First off apologies if this is in the wrong place but I wasn't sure where else to post it.

So I sometimes have my external HD connected to my MBP in the sitting room and I want to share it so that I access it from my MB while in bedroom for the purpose of streaming vids ( not porn ) I have tried multiple tactics and done my best research across the web to no avail. Have tried using ' Sharepoints ' but it keeps crashing .... any other advice would be much appreciated

Enable file sharing on the MBP and the MB will find it pretty much instantly.

I have it enabled on my MacPro and it shares everything from Internal and External HDs and DVDs to USB Sticks.

In system prefs > sharing ? I did that. The MB picks up my MBP and i can see all the folders on my internal drive but not the external :/
