How do I get rid of the Notificationexec error in OS X Lion?
OK. Here is the solution I found, which is terrible but it works. Basically, I went to the Finder, opened the Search Criteria and searched for anything with named Maxtor and Seagate. After deleting several files, one of which had the word notification in it, I don't see the popup anymore. Most other solutions on Apple support site refer to removing files from Library -> Driver Support but I had no such folder. So if no other solution works for you, I suggest that you go to the finder and delete everything as I described above.
