so ok... 3 and 4 tb hard drives need to use this new GUID scheme... but after that is done and we get the single big disk, can it then also be split into more than one partition??
 
thanks but not exactly what I'm wanting to understand...

Let's say I do a GUID partition on a 3TB drive... and then would like to split that into two 1.5 TB partitions... keeping GUID scheme... you see?

so two diff Letter names on the same drive... much like we used to do with MBR drives, right? That is what I don't see anyway to do.
 
Don't really understand what you are asking that hasn't been answered.... if you do what I said, as further explained in the tutorial, you have made a partition of the size you chose.....I usually do 128 or 256 GB .... you have a GPT partition of the size you chose.....1.5 TB is just fine tho the other one will NOT also be 1.5 TB..... you don't get 3 TB out of a 3TB drive cause the marketing folks define a TB as 1000 GB instead of 1024 GB and ya need room for the disk to manage itself.

As you can see in the image in the tutorial, the system created the two necessary system and reserve partitions and then a primary of 172.6 GB. The unallocated space, in the tutorial example (293 GB) when ya ready to do it, can be done (GPT) from within disk management in Windows.

I think we have a misunderstanding. I appreciate your info but it really is not dealing with what I'm wanting.

I am aware you never the full TB or GB size when formatted... I'm not new at computers but I am fairly new to certain thing in this GPT or GUID stuff.

I am not dealing with installing windows... I have win7 64 bit installed on this particular pc. It has an SSD and 3 other 3TB HD's all happy and fine.

What I now have is another 3TB drive in a USB 3.0 external case... OK?

I can make it one big GUID partition just fine. But then in the win disk management console, I find no way to further split that into two partitions, each with it's own drive letter name.

Is that more clear as a question?
 
GUID Partition Table, aka GPT, is the partition table, not the partition. The Windows default is Master Boot Record aka MBR. The reason you use GPT instead of MBR is because of the Logical Block Addressing (LBA) that each uses. MBR is 32bit and GPT is 64bit. This is the number of bits in the unique addresses of each logical block of memory on the disk and has nothing to do with 32 or 64 but CPU architecture. The short and small of it is that if you have a disk with a capacity of 2.2TB or more, you will have to use GPT in order to be able to address all of the memory blocks on that disk. This partion table is chosen when you initialise the disk and it does not alter when you create/delete/extend/shrink/format a partition or volume on that disk.

You do not need any third party software to create or delete partitions on your disk but if you intend to use your GPT disk as a boot disk for Windows, you may very well require a BIOS upgrade for your motherboard, as Windows bootloader looks for MBR disks to boot from.

In order to edit the partitions on your disk inside Windows 7:

Start Menu > riight-click "My Computer" > select "Manage" > select "Disk Management" from the tree in the left hand pane of the window that pops up, towards the bottom of the tree > select your 4TB disk from the list of disks there.

Your existing partitions will be represented as boxes along a horizontal bar. If you have an existing volume/partition crurrently taking up all of the free space on your 4TB disk then you will need to split this into the volumes you require, or you will have to delete it and create new ones to suit. The options to do such things are found by right clicking the partition box to wish to edit.

Under MBR you were limited to 4 logical volumes per disk but GPT does not have this limitation. I think it's 12 or something but that is just off the top of my head...
