Stop vista from scanning my ext HDD

[peterhoang2002]

I have a 1tb external HDD and ever since ive switched to vista, it get's scanned every time i boot up. vista scans it like right after that circle with the windows logo appears during bootup... it shows like a blank black screen for like 2-3 mins afterwards. I was wondering if there was anyway to stop it from scanning this. Ive been leaving it unplugged because of this. Id like to keep my external HDD plugged in.
