Import the clips again from the internal drive.
Then replace the clips on the timeline with these new imports.
Going from memory, but I believe you can right-click a clip in the Project Bin and select "Unlink Media" and then right-click again and "Relink" and point it towards the new version of the file.

When I "Unlinked" media and tried to "Relink", "Relink" was not an option.
What I finally ended up doing was selecting "Reveal In Project" (right click on clip in timeline). Then in the footage bin where the file is highligted, right click to "Replace Footage" and point to the file on my internal raid. Thanks guys for pointing me in the right direction. Now the project is entirely self contained on my internal raid.
Hope this works for anyone having similar issues.
