stevener11, the picture shows three drives.
What is your problem?
IMO, part of your issue you need to give short unique names (labels) to your drives and partitions. Stop calling then C D E F and so on. The drive letters change. And you can have a drive without a letter and still be part of the files system. If you want. But once Windows assigns letters, you ought to leave them. Changing the label of the drive is OK and it helps one to organize things.
In Windows 7 there is no need to call a drive a 'logical' drive. In fact, the picture you show does not have any drives called 'logical' drives. Notice they are all called primary drives.
Which drive is it that you can not find? The picture is not wide enough to see all the names and letters.
