This works directly, e.g.:
FID = fopen('/media/ext_hdd/YourFile.ext', 'r')
This works exactly as for files on the internal disk. So please explain, what you have tried and which problems occur.

dir() does not use the search path. But you can use
projectdir = 'D:\AHN3\DSM05';
filelist = dir(projectdir);

It is a bad programming practize to call addpath to append a folder containing data files. Include only folders in the Matlab path, which contain your M-files.
To get a list of files:
filelist = dir('D:\AHN3\DSM05');

I wanted to access data files on a external drive named "My Passport" in matlab using my MAC. The following is example of the path layout for the filename to make that happen:
fname ='/Volumes/My Passport/Tower_Collect/201808B.raw';
The data was successfully loaded and processed
