Simple Disc Management

When a drive has been installed in the computer or inserted on a port, the operating system must recognize it. Once it does, for a computer that runs Microsoft Windows, it assigns a letter to it. In Windows Explorer or My Computer, a drive is represented by a letter. Here are examples:
Each letter, in this case A, C, D, E, F, and G represents a drive. Most computers should have less drives than that and some computers can have more drives than that. In some cases, a letter may not represent a real drive physical drive (it may represent a partition among many partitions on the same har drive). To distinguish a letter of a drive from letters of normal words, the letter of a drive is always followed by a colon ":". In Windows Explorer or My Computer, the letter of a drive is also included in parentheses.
In most cases, you should accept the letters, In some cases, you may need to change them. For example, if you insert a flash drive, you hear a sound that the computer has recognized it, but the content of the drive doesn't show, or the drive letter is not (automatically) assigned (by the operating system). The problem could be that the letter the operating system attempted to assign to the drive is already taken but the operating system didn't attempt to assign another letter.
To manage the letters of the drives, you can open the Computer Management MMC. To do this, you can right-click My Computer and click Manage. Then, in the left frame, click Disk Management:
One of the actions you can perform here consists of changing a drive letter. To do this, you can right-click a drive letter in the top-right frame or a section in the lower-right frame and click Change Drive Letter And Paths... This would open a dialog box that you can use to change the letter.
