Serious hd activity
 

Downloading a large file (700mgs) and my hard drive is going nuts with activity. I have a T1 connection, and no uploads/downloads except for this one. The speeds vary between 10 and 150 kbs. It also slows my computer down while using it. Granted it's a crappy computer. P2 350 256 MB ram, but i've never had a program dominate my resources like this. Especially not a file sharing prog.
Is this normal for X or is it something with me?
