First way to fix this is the most basic method and I would say try this way first; if it won't work then move on to the second method (command line). I do not have a good answer to why the graphical user interface method sometimes fails, but if it does you can always go to the command line method. So first step is to go to "My Computer" and find the drive letter and right click on it. In the drop down menu that will popup you will want to click on the last option that says "properties". In the Properties dialog box you will want to choose the Tools Tab. In this tab you will want to run the Error-checking tool, there is a button that says Check Now... click this. In the new window you will want to check mark both options (automatically fix file system errors) and (scan for and attempt recovery of bad sectors).
The program should run through and if there are any sectors or issues with the file system or boot sectors it will fix them for you. If the program says it completed successfully then you can try to open your flash drive, if you are successful then you are done. If the program just blinks and then stops and never prompts you that it has finished then it didn't work and you need to move on to the command line method.
The command line method will seem way more complicated and intense but it really isn't. All you will need to do is go to "Start" and choose "Run". In the text box that comes up you will want to type "cmd" and hit enter. This will open a command line text prompt that we will use to fix
our flash drive.
In the new window you will want to type chkdsk this is for checking the disk, and then we have to enter some parameters so the computer knows what to do to the flash drive. The next thing you will want to type is the drive letter of your USB device; you can find this by going to "My Computer" it will be next to the drive in the window. Once you have both of these then we will put our parameters to fix the drive, the two we will use are \f and \r.
The /f Fixes errors on the disk. The disk must be locked. If chkdsk cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer.
The /r Locates bad sectors and recovers readable information. The disk must be locked.
So now that we know what our commands do let me spell out the command line that you should have typed.
C:\>chkdsk E: \f \r
Now the one thing in this command that can change a lot is the letter of the drive, mine is E: yours could be almost anything from A to Z so check and be sure you get the right drive letter.
Once you have the command line text entered correctly then you can hit enter and it will run through and fix the file system on your Flash drive. Once it is done then you can check to be sure it worked. Once it works you should be able to get to all the files on your flash drive and use them just as before.
