iPod 4g 40GB iPod formating new HD

[petermuir]

I need to reformat a HD to work with my 4G 40GB iPod. The current HD partition map reads as follows:

Partition map (with 512 byte blocks) on '/dev/disk2'
#: type name length base ( size )
1: Apple_partition_map Apple 63 @ 1
2: Apple_Free 262144 @ 64 (128.0M)
3: Apple_HFS Apple_HFS_Untitled_1 77863824 @ 262208 ( 37.1G)
4: Apple_Free 16 @ 78126032

The partition map for a 4G 40GB iPod reads as follows:

Partition map (with 512 byte blocks) on '/dev/disk2'
#: type name length base ( size )
1: Apple_partition_map partition map 62 @ 1
2: Apple_MDFW firmware 65536 @ 63 ( 32.0M)
3: Apple_HFS disk 78060440 @ 65600 ( 37.2G)

Device block size=512, Number of Blocks=78126048 (37.3G)
DeviceType=0x0, DeviceId=0x0

Grateful for any advice as to how I can get from the current HD partition map status to the desired one.
