Another thing to keep in mind is that the iMac G4 uses Parallel ATA bus for its internal drives. The drive controller may not have 48-bit LBA (Logical Block Addressing), which allows for partitions to exceed 128 petabytes (128,000,000,000,000,000 bytes). The older standard limited you access to about 137 gigabytes (1,000,000,000 bytes) per partition.

So, in short, make sure the first partition contains at least 128 gigabytes (just to be on the safe side) and what is left over goes in the 2nd partition. If your model iMac G4 supports Mac OS 9.2.2 along side an installation of OS X (and if you plan on doing so that way), make sure the first partition is about 7 or 8 gigabytes in size (for OS 9), install OS 9 on that, about 128 gigabytes on a 2nd partition (for OS X) and whatever is left goes in a 3rd partition. That's how I would deal with a drive that large on a Mac like that. The same applies to any drive larger than your 250 GB capacity.
