Re: my two front usb ports cant read usb hard drives
Some external USB drives require external power sources. Typically this is done either with an external power supply that connects to the drive or a second USB cable that connects to the drive and a second usb port on the pc. I have even seen one drive that comes with a Y cable. one end goes to the drive and the 2 usb plugs go to the pc.

You didn't mention the manufacturer on your 16GB stick, but that should not be a problem using it. The price on 16GB USB drives has fallen dramatically in recent weeks, so you will see more of them in use.
If you plug the USB drive into one of your computer's free USB ports, it should be recognized by your computer and assigned a drive letter in Windows. This means if you view the contents of your hard drive using Windows File Explorer, you should see another drive representing the 16GB USB thumb drive in the list of disks.
If you click on that drive you will see its contents (if any). Some drives come with software pre-loaded on them which you may be able to use to encrypt the contents of the thumb drive.
In all other respects, the USB drive will function like any other disk drive, allowing you to move or copy files back and forth between your main hard drive and the USB drive.
Be careful to 'unmount' the USB drive before you remove it from the USB port. Often there will be a flashing LED light on the drive which indicates that data is being written to the USB drive. If you remove the drive while the light is blinking, you may damage the file system on the USB drive and make reading its data impossible.
To eject the drive properly using Windows File Explorer, click on your main hard drive (usually C:) to select it, then RIGHT-CLICK on the drive you want to eject. A menu will come up, and you should click 'Eject' to close out the USB drive. You will get a confirmation message window that it is safe to remove the drive.
Try it on another computer. If it works, then your computer's USB port has problem. Check the ports and make sure they are properly connected and are cleaned. Also make sure the USB driver is updated/installed. You can also try it on another USB Port of your computer. If it doesn't work on another computer, then I would say your Flashdrive is bad or gone.

look on the back of your computer for a hi speed usb port, or just use any back usb port. some computers like mine dont have a "bus" to the mother board to the front usbs or because they are piggy backed to the front they dont pass through.
Hello sir/ma'am, hi, most likely you have cable problems, check and see if you can find another cable. The cable is the USB data cable, that connects from your PC to the external hard drive.
Please also check if your USB port is working fine, just simply plug in a thumb drive to confirm.
If its not the cable, its the external hard drive. Usually, the red light appears or the device is reading the drive continuously with no action. let me know your progress.
Try any other computer but not open drive only see if they can read it. Also change USB port, sometimes some ports dont accept devices. Also check for latest antivirus software last such case viruses dont let me read any of my USB drives. If driver works to oter PC then you have virus.
If your system is USB 1 rather than USB 2 then some flash drives will not work. Not all usb 2 flashdrives are backwards compatible. My kids flasdrives will only work on my usb2 ports & will not work at all on my wife's computer which has the older usb 1 ports.
