Computer Won\'t Detect any external Hard Drives

My computer will not read any hard drives that I plug into the computer. It will read USB but no external Hard drives. I have tried several different types of hard drives as well which work fine in other computers. It has read them before, it recognizes that there is something plugged in because you can still safely remove it. I am stuck at this point it is not flagged in device manager.

  1. Can you read a pen drive?

    Are these hard drives powered from the USB port?
  2. It can read read pen drives and yes it is USB port powered.
  3. Erm, most 2.5" drives get away with running off a Usb port if so. But if you are trying to use a 3.5" Sata drive to usb you need to have a 12v power adapter to run some of them located on the back of the enclosure it`s in. Make sure it is a 2.0 or 3.0 usb port aswell.
  4. The Hard drive used to work on the computer and continues to work on others, the drive is functioning and so is the USB port.
  5. How does Microsoft's UVCView utility see the external drive?

    This is the info from the program thatfzabkar gave me provided
  7. You are showing two devices. The SuYin device is a 1.3M HD WebCam.

    http://forums.opensuse.org/english/get-technical-help-here/laptop/461634-acer-aspire-5253-bz602-sound-problems.html

    The second appears to be a WD Passport drive. I don't know if the errors are real, or whether they reflect some other issue. If the webcam works, then this would suggest that the errors are not real.

    Is your pen drive reported differently?
  8. Type "diskpart automount enable" in command prompt, see if that helps.
