PacketShaper hard drives must be correctly partitioned and formatted before they can be recognized by the PSOS operating system used on PacketShapers.
A correctly partitioned and formatted hard drive would have four partitions which look like this:
Partition Type Size Primary/Logical Beginning Cylinder Ending Cylinder
1 FAT16 2047MB Primary 0 260
2 FAT16 2047MB Primary 261 521
3 FAT16 2047MB Primary 522 782
4 FAT16 1890MB Primary 783 1023
