I have a 32GB USB flash drive. It dosent show up on "This PC." I am running Windows 8.1. I went into "Disk Management" and it showed up as healthy and working. I tried to change the letter but that didnt work or help at all. I am out of ideas on why it isnt working.

As dijk mentioned, what filesystem was the flash drive formatted with (Windows or Mac)?
Or more so, was it formatted at all?

One other possibility is that the drive was used on this PC before, Windows cached the device but the USB channel it was cached under/linked to, is either invalid or in use by another device.

Check the formatting first.

If it was formatted, try formatting again (use whatever the native type it should use).

If formatting was fine, then:
- First, disconnect the drive then download USBdeview (download link is -almost- at the bottom) and check to see if there is any entry related to the drive indicating it was disabled or not. It would be odd but if that is the case, enable it.

- If the entry shows disconnected, simply remove/delete it. If it shows up as connected, first disconnect it then remove it.

I usually sort the list by clicking on the "Device Type" column then locate the drive by model under "Device Name" column. The manufacturer will also be listed under the "Description" column:

Afterwards, better to reboot the machine and then connect the flash drive to see if it shows up.
