Apart from your companions' quests I don't remember many side quests being connected to the main story in KOTOR.
I'm not talking about directly linked into the main story, in KotOR you're not really dumped into the main story straight away. Even though you know that Malek is after Bastilla, and up to something in general, the fact she is with you for most of the game means there's no urgency. And since you don't know who might give you a clue to the Sith's plans you can feel justified in exploring and helping the little people while remaining in character. But in Mass Effect you have the main plot shoved up your... right away, there's no avoiding it and staying in character. If you know the galaxy is in peril are you really going to take time out to help an addict get a fix or survey mineral deposits? The only time you can justify searching uncharted worlds is when you are looking for Liara.
The icing on the cake was after I had left the Citadel for the final time, and was about to travel to the main story's point of no return. I'm a fugitive, on a stolen ship racing against time to beat Saren yet as soon as I go to the galaxy map I get a comm message from the Alliance to go rescue some hostages. Okay command might not of been up to date on my situation but would my character, good or bad really go off and make the detour? I don't think so.
