For disk managemet:
To initialize new disks
Click Start > Run and type diskmgmt.msc
Right-click the disk you want to initialize, and then click Initialize Disk.
In the Initialize Disk dialog box, select the disk(s) to initialize.
On x86-based computers running Windows Server 2003 with Service Pack 1 (SP1), Itanium-based computers, or x64-based computers, you can select whether to use the master boot record (MBR) or GUID partition table (GPT) partition style.
The disk is initialized as a basic disk.
To open Computer Management, click Start, and then click Control Panel. Double-click Administrative Tools, and then double-click Computer Management.
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.
New disks appear as Not Initialized. Before you can use a disk, you must first initialize it. If you start Disk Management after adding a disk, the Initialize Disk Wizard appears so you can initialize the disk.
