When you FDISK  drive, you can create a primary partition and and extended partition. In the extended partition you can have 1 or more logical drives. In the primary partition you can only have 1 drive.
So, Windows and Dos line up the  drives like this:
All of the primary partitions, then all of the logical drives in each hard disks extended partition in this order: primary master, primary slave, secondary master, secondary slave.
If your friend creates a primary dos partition and one logical drive on each  hard disk, it will turn out as you expect: that C: is the first hard drives first partition, and D: is the first partition on the 2nd hard drive, E: is the first hard drive's extended partition, and F: is the 2nd hard drives extended partition.
But, if he somehow makes ONLY an extended dos partition on the second hard drive (I don't think you can do this with just dos, but you can with linux fdisk) then the 2 drives on the 2nd hard disk's extended partition will line up as you saw -- E: and F:

The primary partition for the first drive is C: and the primary partition for the second physical drive is d:.
Then Dos goes back to the first drive to assign drive letters in sequence.
You can read all about it in the K/B aricle here:
