The answer is right there , it is UnFomatted.

So in Disk Utility select the drive, click on the Partition tab, Select One partition from the Partition Layout drop down box, Select Options and make it GUID, then either give it a name or not, select Mac Extended (Journaled) as the format and hit the Apply button.

If it comes back as Not Formatted then the drive is bad even though you may be able to read it on a Windows PC.

OK, as others have suggested, you need to format it.

1. Open Disk Utility.
2. Select your flash drive.
3. Select Erase.
4. Select a format. I recommend choosing MS-DOS (FAT), since you have a PC, and you should want it to be readable by both systems. If you don't, select Mac OS Extended (Journaled).
5. Give it any name you wish.
6. Check it.

If this doesn't work, the problem is with your drive.

Yeah the drive is no good. Buy a new one.
