I have a 1 GB Kingston USB Drive which was working peoperly for about 2 months. Now suddenly, a strange problem has occured. When I plug it in, my pc accepts it and assigns a drive letter to it. If I ckick on the drive letter in My Computer or in Windows Explorer, an "Access Denied" error is shown. But if I use the Autorun Menu, then I can open the USB drive from there. In simpler words, I cannot access my USB drive through "My Computer" or "Windows Explorer" directly but can access it from the Autorun menu that pops up when I plug in the drive. I checked it on another PC and found the same problem there also. Both systems are having Windows XP with SP2.
