I wonder... if I'll use the script and enable the 48bit LBA, I think Disk
Utility will then show the unused portion of the drive.

No.
Actually, it does. :-)
(I'm on a PowerMac G4 DA with 10.4.11 - 250MB WD HD)

After using the script (and rebooting), Disk Utility shows (in the Partition
tab) a new 104,89GB "free space" area...
but I can't do anything with it. :-/
(perhaps because that's the boot drive)

I'm not an expert on this, but it seems reasonable to me that since this area has not been partitioned, the added space has not been "mapped out" by the OS so the OS cannot access it. It says the space is there, but it cannot address any of it ...

Whether you use the LBA48 technique, or buy a PCI ATA/IDE card, the extra space still hasn't been mapped out by the OS. I believe it all has to be linked together at the initial partitioning time as well.

Like I said earlier, I'm not one of the experts on this forum, just adding my intuitive feelings about the matter.


... I'll take the time to do some heavy backup, before partitioning the new
HD space.

Best idea.
