1.3 GB removable disk formats to only a 1.0 GB partition?

Question

I'm running into an odd problem. I have a Fujitsu DynaMO drive which uses 1.3 GB disks. Disks I've already formatted are recognized properly with roughly 1.2 GB of free space. However, formatting a new disk results in a 1.0 GB -- exactly! -- partition.
I verified with diskutil that the partition size created is $80000000 blocks. I haven't found a way with diskutil (yet) to convince it to generate a partition which allows me to use the full space of the disk. This is rather annoying.
Anyone else seen this? I'm using Leopard, 10.5.2, on a MacBook Pro.
And no, this is not the megabyte-vs-mebibyte issue.

Answer 1

I get the full capacity if I use two partitions:
% diskutil partitionDisk disk1 2 APMFormat JHFS+ "Untitled" 50% JHFS+ "Untitled 2" 50%
#: TYPE NAME SIZE IDENTIFIER
0: Applepartitionscheme *1.2 Gi disk1
1: Applepartitionmap 126.0 Ki disk1s1
2: Apple_HFS Untitled 591.7 Mi disk1s2
3: Apple_HFS Untitled 2 591.5 Mi disk1s3
but with one partition, it's clamped to 1 GB:
% diskutil partitionDisk disk1 1 APMFormat JHFS+ "Untitled" 100%
#: TYPE NAME SIZE IDENTIFIER
0: Applepartitionscheme *1.2 Gi disk1
1: Applepartitionmap 128.0 Ki disk1s1
2: Apple_HFS Untitled 1.0 Gi disk1s3
