On an article on the new Windows 7, I read the following.
Old bug with removable storage media resolved.
In Windows XP and Vista, there is a bug that if you have a mapped network drive, for example, on E:, and the device is the next available physical unit mapped as the removable media on E:. It then becomes impossible to access the content on the network drive. This bug is corrected in Windows 7.
