i think it has to do with the 2.0 usb speed, it only happens between usb and hardrive, and deleting off the usb, cuz i tried deleting from the hd today and it was fast as normal.

edit:

Ok, i think i know whats worng but i dont know how to fix it. When i plug in my usb a new message appears saying that its not plugged into a 2.0 speed usb, however, i have a seperate card in the back which was installed with 4 2.0 usb ports and two firewire.

It tells me to click to see where to plug it in, and it says i have 4 unused 20 usb ports, so they should be the card ports, right? So i plugged it in there, and it says the same thing, not to mention other things are plugged in there as well, and the comp says that the 4 2.0 usb are all not in use at the moment. I don't have any other 4 empty usb ports. I have two in the front, which aren't 2.0 for sure, and the card in the back with 2.0. I tried plugging it in directly to the card and through the 2.0 usb hub in the card.

Any ideas?

the card with 2.0 usb didn't come with a driver installation, could that be something? I also went to device manager to update all usb port drivers, and it says they're all fine.
