How To: Correct the Mistaken Available Space on a Flash Drive

Hello, everyone. This tutorial is for GNOME. Easy to translate for other DEs/WNs, however.

For a long time, after deleting a large amount of data from a flash drive or MP3 player, I would see something like the attached image.

Where I have an 8.0 GB Flash drive with no files, but also no space.

The simple "" solutions are as follows:
1. Ctrl+H to view hidden files, and delete all of them.
2. Empty your desktop trash, and also your root trash.

But sometimes, like in my example, there are absolutely no files on the drive, or in any trash bin.

This problem remained a constant annoyance, bother, and mystery for me until just recently.

Here's how I fixed it.

Step 1
Follow System --> Administration --> System Monitor --> File Systems. Take note of your flash drive. In my case it was /dev/sdb1.

Step 2
Follow Applications --> Accessories --> Terminal and run the following command, replacing /dev/sdb1 with the name of your flash drive.
Code:
sudo dosfsck -rV /dev/sdb1
Step 3
Press 1 to "backup to original" if this is an option.
then,
Press 2, for "Correct," followed by a "y" to confirm.

Step 4
Unmount, then remount your flash drive, and all should be well!
