Re: Rereading A Partition Table



Duane --

I'm making changes to GUID partition disks partition table, and I would
like the system to re-read the disk in order to recognize new partitions
on the disk. 

What do I need to do to get the system to re-read the disk and recognize
the changes?

I've tried several disk util commands (unmountDisk, mountDisk, and
eject) but they don't re-read the disk. 

Disk Utility->Eject does the same thing (ie nothing).

I note that this is a FireWire drive, but it could also be an internal
drive or any other non-network drive.

For example, when Disk Utility partitions a disk, it fully unmounts and
then remounts the disk. How can I do the same thing?

Try opening and closing the raw disk node for the whole device.
