Hi Shaun, similar problem here, but not LaCie.
First, PPC Macs need APM Partion scheme & are limited to 2.2 TB drives.
Second, many newer drives are not bootable on PPC Macs due to the chipset used in the enclosure, which is my problem with a new FW/800 2.0 TB drive that cloned perfectly & DU/DW/DG report as fine, shows up in Startup Disk, but not in alt boot, & results in gray screen if chosen to start from.

Ah - didn't know about this chipset business. Will see what LaCie have to say. Maybe they'll swap it for the 2Tb drive if that isn't affected by the chipset.
Partition is APM, as recommended, but where does it say PPC Macs are limited to 2.2Tb drives?
Does this mean the OSX system can't run a drive bigger than this, but the drive can still be used for storage and retrieval up to its (here 4TB) limit?

It means that PPC hardware isn't capable of reading or writing more than 2.2 GBs of the drive.
OS X 10.5.8 may also limit what it can see for external drive storage space, also, but not sure about that.
There weren't large TB drives back when PowerPC Macs existed and when OS X 10.5 Leoprd came out.
That's why there is this limitation.

PPC Macs running 10.4.11 & up can read & write to GUID Partition scheme, but not boot from it.
I doubt the 2 TB one uses a different chipset.
Every disk has exactly one partition scheme. A disk can be partitioned as "Apple Partition Map" (APM), "GUID Partition Table" (GPT), "Master Boot Record" (MBR), or the Fdisk partition scheme. PowerPC Macs could only boot from a disk that is partitioned with the APM partitioning scheme. Intel Macs can boot from a disk that is partitioned with either the APM or GPT partitioning scheme.

OK. Thank you all for your help. Basically I can run this drive as a 2Tb non-bootable drive for storage purposes, with no way of using the full 4Tb I bought it for. Is that right?

A thought - APM restricts me to 2Tb, so ... if I format the 4Tb LaCie using the GUID format I still won't be able to boot from it, but - and if this sounds stupid I plead old age* - can I then use the full 4Tb to read and write?
I've looked through all the documents but this point doesn't appear to be mentioned.
*just turned 74 and not as sharp as what I once was ...

Yes, that is how it is supposed to work.
