Tested all my flash drives on the both front header, they all show pop ups. but when i put my external hard drive it doesn't on 1 front header.
If your external hard drive is not showing a notification or pop-up when plugged into a specific front USB header, it's likely that there is an issue with that particular USB port or its connection to your motherboard.You can try the following solutions:
1. Check the cable and ports: Check the cable and ports of your external hard drive to ensure that they are in good condition and not damaged. Try connecting your hard drive using a different USB cable or to a different USB port.
2. Check the device manager: Check your Device Manager to see if the USB driver and external hard drive are recognized. If they are not, try updating the USB driver or reinstalling the driver for the external hard drive.
3. Check the BIOS settings: Check your BIOS settings to ensure that the front USB port is properly enabled. To do this, restart your computer and press the key to enter the BIOS setup. Look for settings related to USB or "Front panel USB".
4. Disable USB Selective Suspend: USB Selective Suspend is a power saving mode that can sometimes cause issues with external hard drives. To disable it, navigate to the Power Options in your Control Panel, click on "Change plan settings" for your current plan, then click on "Change advanced power settings". Expand the USB settings, then expand USB selective suspend setting and change it to "Disabled".
5. Check the power supply: Try connecting your external hard drive to a powered USB hub or using an external power supply if one is available. Some external hard drives require more power than a USB port can provide.
6. Check the USB controller: If the above steps do not work, there may be an issue with your USB controller. Try uninstalling and reinstalling the USB controller driver or updating the USB controller firmware. You can find these in the Device Manager under the "Universal Serial Bus controllers" section.
If none of these solutions work, it could be a hardware issue with your USB port or external hard drive. You may need to take your computer or external hard drive to a professional technician to troubleshoot further.
