    I plugged my external hard drive into a computer at work and it was not recognized. So I tried another computer at work and it still had the problem. Now it happens on my home computer also. I tried it with a flash drive and it also happened. I suspect that the first computer at work did something to cause this.

    I have tried rebooting and unplugging my computer with the device attached. Troubleshoot hasn't helped. I tried uninstalling it and updating software/drivers but it doesn't do anything.

    Any advice is appreciated.

    Is this a drive that was purchased as an external drive, or is it a hard drive inside of a USB enclosure?
    (what's the make/model?)

    It sounds to me as if the drive has failed..but please provide a bit more information.

    It happened to both my Western Digital Portable Hard Drive, and an HP 4GB flash drive.

    Have you checked both drives for malware and/or viruses recently?
    If not, I would suggest doing so with both Malwarebytes and
    Superspyware.

    Is there a way to scan a device for viruses if it is not listed in Explorer?

    You could attach each drive and go into the BIOS to see if it recognizes either..many mobos don't. If the drives are recognized in BIOS, you could use a bootable antivirus program, I believe AVG makes a free bootable "rescue" app.

    Another option is to attach a USB to Sata (or IDE) adapter and see if the drive(s) can be detected that way.

    Try other USB drives on the computers also to rule out the ports as the problem.
