I dont there is much you can do other than formatting it
Here are the steps for you to format the drive in Windows. This will erase any data that is on the drive. If you right click your Windows my computer icon, or Windows computer icon, click on manage.
On the left double click Disk Management.
Your drive should show.
With your mouse right click the drive,and click format. If you have windows vista or windows 7 you will choose delete volume and then you should get the option to create a new volume.
