As usual things are not as simple as they should be with Windows! You'd think that if you're using Vista or later it would be a simple matter of querying the WMI class Win32_DiskDrive to get this information: http://msdn.microsoft.com/en-gb/library/windows/desktop/aa394132(v=vs.85).aspx However for the devices I tried the SerialNumber property gave silly answers and the InstallDate property didn't work at all! I did eventually figure out that you could parse out the serial number from the PNPDeviceID property and the following code shows how to do that: using System; using System.Management; class Test { static void Main() { var searcher = new ManagementObjectSearcher(SELECT * FROM Win32_DiskDrive WHERE InterfaceType = 'USB'); foreach(ManagementObject drive in searcher.Get()) { string caption = drive[Caption].ToString(); string deviceId = drive[PNPDeviceID].ToString(); string[] items = deviceId.Substring(deviceId.LastIndexOf('\') + 1).Split('&'); string serialNo = items[items.Length - 2]; string installDate = Unavailable; object temp = drive[InstallDate]; if (temp != null) installDate = temp.ToString(); Console.WriteLine(caption); Console.WriteLine(PNP Device ID = {0} deviceId); Console.WriteLine(Serial Number = {0} serialNo); Console.WriteLine(Installation Date = {0} installDate); Console.WriteLine(); } Console.ReadKey(); } } As far as the log in date is concerned I couldn't find any way to get at this statically but there's a Code Project article here which shows how to detect in real time when devices are plugged-in and removed which may be of some help to you: http://www.codeproject.com/Articles/63878/Enumerate-and-Auto-Detect-USB-Drives#AWalkAroundWMI
