You're now ready to create your new partition. Notice that you aren't creating another extended partition on the first disk. Last month, we created the second extended FAT16 partition on Hard Disk 0 for use with Windows NT Server. Next, we created a logical 2GB drive in the extended partition. So, although it seemed that you simply created a 2GB extended partition and formatted it with FAT16, you really created a 4.2GB extended partition and broke it into a 2GB logical drive and 2.2GB of unused space.
Logical drives are simply partitions within existing extended partitions.
Now, let's add a second logical drive with drive letter E, using the remaining space available on the extended partition. At this point, you've used all the available space on Hard Disk 0. Formatting the new partition with FAT32 Select Microsoft Windows from the boot menu and let the Windows GUI boot completely. Then, double-click My Computer to view your system configuration, which should resemble the one shown in Figure E . At this point, you haven't formatted the drive, so you can't access it.
