I have reformated my HDD after it was infected by a malware and installed Windows XP Professional SP2. Then I pluged in my USB external drive and found out that when I click on the Drive icon/letter nothing happens. I have to right click the drive icon and choose "open" for me to access its contents. I checked the other drives and it showed the same problem as well. The only affected icons are the Drive icons...when i double click on the folders it opens.
