Beg or borrow an USB 2.0 hub. Try various combinations with that.
So, just like the title says, I have two external harddrives. One is a WD 500GB, and the other is a 250GB (not sure the brand). I've got an Dell Inspiron 600M, Windows XP SP2. Since I tend to be long winded, I'm going to try and bullet my situation:
-I have 2 external harddrives
-Either harddrive plugged into my USB by itself runs fine
-If the 500GB is plugged in and I try to plug in the 250GB, the computer freezes up, and responds very slowly (if at all to any mouse or keyboard inputs).
-The 250GB takes a very long time to load (only when it's being plugged in while the 500GB is plugged in as well
-If I turn off the 250GB after I have plugged it in, and the computer is frozen, the computer returns to normal.
What could be causing this kind of behavior? Is there something about my computer and handling two external harddrives at the same time? Any help is appreciated, thanks.
