I have two seagate external harddrives, one being a 2TB and a portable 500 gig. I purchased the 500 gig about a year ago and it installed seagate manager on my laptop. I just bought my 2 TB and when I doubleclick it it will run the seagate manager installation. I don't know why this occurs since I can see my new 2TB on the list in seagate manager. I tried updating the software and deleting the files off the new 2TB, but that did not fix anything. I can right click and open it from the menu, but I would like to know if there is a way to fix this annoyance.
