So lately, when I've put pendrives in my computer, the green arrow (safely remove hardware) icon shows up in the taskbar, windows makes the ding sound indicated i've plugged in a usb device, but the box doesn't pop up asking if i want to view folders and when i go to my computer, the drive doesn't show up. if i restart my computer, and then put the pendrive in, it will usually work the first time, but after that, i have the same problem. any ideas on what to do? i haven't always had this problem, and i haven't installed any new hardware. i'm running xp.
