I have a portable hard drive and it usually works fine. However, if I change which computer i have it hooked up to, and then bring it back to the origional PC the drive letter has changed. This isn't a problem except for that it leaves one music making program i use innaccessible. Is there any way I can keep the drive letter static, or perhpas manually change it back to the letter I want? It should be my J drive but now it's my H.
