udev/hotplug does abolutely the right thing.
The sda node is the whole disc. You may install a  bootsector by
writing block 0 of sda, so you need this node to be created.
sda1 and sda2 are your data partitions. You can print the partition table
with "fdisk -l /dev/sda" and you will see two partitions there.
Maybe you just don't use the second partition now.

This is what udev creates for the first IDE disc:
  brw-r--r--    1 root     root       3,   0 Nov  5 20:14 hda
  brw-r--r--    1 root     root       3,   1 Nov  5 20:14 hda1
  brw-r--r--    1 root     root       3,   2 Nov  5 20:14 hda2
  brw-r--r--    1 root     root       3,   4 Nov  5 20:14 hda3


and this is the partition table:
  Device Boot      Start         End      Blocks   Id  System
  /dev/hda1               1         992      499936+  82  Linux swap
  /dev/hda2             993       20368     9765504   83  Linux
  /dev/hda3           20369      155061    67885272   83  Linux
