My second hard drive (labeled D) was giving me this very problem. What happened was, I swapped the main C drive out for a different one and reinstalled Vista on it as a test for the drive. Well, then I plugged in the D drive and things went ok...until.....
A friend of mine lost his hard drive in a crash so I sold him the one I had just put in (i figured since the other one was the same size and speed but newer, and it had all my apps and games already on it I would keep that one, right? Even if it was a different brand.)
So I put in the previous drive and fired it up.
BANG! All my stuff right back as I remember. Of course it would be. I knew that.
But....
UGH! I cannot cut and paste or copy anything to the D drive now??!! WHAT!!??

So....
After 3 hours of fighting with Vista this is how I fixed it:

Go to MY COMPUTER
Right click on the DRIVE that is causing trouble (not the folder, but the actual drive EVEN IF IT IS THE MAIN SYSTEM DRIVE)
Click PROPERTIES then click the SECURITY tab

Change the ownership of the entire drive.

You will see your name twice (labeled as administrator and user)
BOTH need full permissions
BUT your USER version needs to be the OWNER of the drive.
After changing ownership, apply full permissions to yourself (stupid...i have to give MYSELF permissions on MY OWN pc...thanks MicroCrap!)

Apply all the changes and let me know.
