On a machine, I dual-boot Windows XP and Windows 7 (both 32-bit).
Several external hard drives work well under Windows XP, but under Windows 7 none of them is shown as a drive in Explorer.
The only thing that happens under Windows 7 is: after plugging in the USB cable, the system recognizes a plugged device and shows the "safely remove hardware" toolbar-icon (which refers to some Bridge device).
What can be the reason?
What additional information could I provide to clarify the problem?
