1. Right-click My Computer and click Manage.
2. In the Computer Management window, under Storage, click Disk Management.
3. In Disk Management, right click the Unallocated partition. Click "New Simple Volume" and the Write
Signature Wizard pops up.
4. Use the wizard to write a signature to the new drive. If you want only one partition we suggest using a
primary partition and selecting the maximum size. In most cases you’ll want to use NTFS volumes, this is
the default for Windows XP and Vista. Ensure "Perform a Quick Format" is checked. Choose FAT32 if you
want to use the drives with older versions of Windows, or if you want to use the drive with Windows and
Mac OS.
5. Formatting will take a few minutes, after which your drive will be ready to use.

Note - Formatting for Windows 8 and above is the same once you are in Disk Management.
