I am using an external HDD for backups on my WIN 2008 server. Recently I applied monthly updates and this caused my ext hdd to stop working. It doesnt show up in My Computer and in Device Manager is showing with a yellow triangle and this the error message that I have : Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available. Mars

Select the yellow triangle in Device Manager, right click, and select Uninstall Driver... When the device has finished uninstalling, select Scan for new devices and it should auto-detect the drive and reinstall the drivers.If you found this post helpful, please "Vote as Helpful".

Hi, Cause: There are several causes of Code 39 errors: A required device driver is missing. A required binary file is corrupted. There is a problem with the file I/O process. A driver that is referencing an entry point in another binary file is unable to load. Recommended resolution : Reinstall the drivers for this device. Uninstall and reinstall the driver Uninstall the driver from Device Manager, and then scan for new hardware to install the driver again. You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s Web site. On the device Properties dialog box, click the Driver tab, and then click Uninstall. Follow the instructions. Restart your computer. Open Device Manager, click Action, and then click Scan for hardware changes. Follow the instructions.
