Earlier this evening, I copied some files to a 16 GB flash drive. When I was done, I right clicked on the desktop icon and selected unmount. A dialog box which said it was safe to remove popped up. So I removed it. A little while later I plugged it back in to recopy a file I had changed. Only one the video podcast folder and my bookmark back-up is displayed on the drive. Yet, it says there are 8 files with 12.1 GB of the 16 being free. It won't let me do anything with it cause it says it is read-only.
How do I get full access back?
