Problem deleting files from USB Flash Drive

[lambatech]

I have a kingston 4 GB USB Flash drive .when I try to delete a file from my pendrive it says "The operation can’t be completed because an unexpected error occurred (error code -1407)." But when I right click the mouse button and select "Get Info" from the drop down box it shows that the file size is zero bytes. What to do ? Please help.

Copy off anything you want to keep and then re-format the drive using DiskUtility.

Also in the future, make sure to empty your trash before ejecting the drive after deleting files. I've had corrupted files not deleted before when I deleted the file then ejected the drive without emptying the trash.
