flash drive problems

I am trying to move a small movie from my desktop to a flash drive. I receive the error "modifying remote disc requires an administrator name and password"....to move file click authenticate'. I tried a different flash drive and different files (pictures, pdf, etc). I get the same message every time. I've reformatted the flash drive through disk utility, etc... TO no avail. Flash drives have always worked on my Imac in the past. Not sure what has happened here.


Any input would be appreciated. thanks.

iMac, OS X Yosemite (10.10.2)
