Clarification Request
Many flash drives have a switch
by wpgwpg May 3, 2013 2:42AM PDT

Have you looked to see if your flash drive has a write protect switch? Some do. If yours does, try setting it in the other position and see if you can write to it then.

Good luck.

USB Flash Drive Write-protect switch
by honhoen May 5, 2013 11:44PM PDT

Hi - thanks for your suggestion -- my drive does not have a write-protect switch; good to know that some drives may have this however. I was able to reformat my drive from NTSF to an OS X format using Disk Utility - something I was not aware was possible with a flash drive.
Regards, JF

Why not format it again with an apple file system?
