(Archived) best method of linking files?

[evernoteuser 0]

Having looked into evernotes and liked what I have seen so far I am thinking along the lines of having a protable EN database on a usb stick and a separate encrypted "pocket" drive for non-synched Data. I would organise media data solely by linking to the files within the notes. The issue I see here though is when I move to a new computer the drive letter may change and thus the links would no longer work. If I used an uncommon drive letter such as Q then I may have less mounting issues however it isn't infallable.

I am just wondering how other people have solved this problem??

Thanks
