I just got a pair of new 3TB disks that I wanted to put on my Windows 2003 server enterprise x64 system, SP2, all updates installed.
When I first tried to convert to dynamic, I got the error "The operation did not complete" as described in this KB article
It says there is a patch, but there is not one for x64, just x86 and ia64
I found another technet discussion here: https://social.technet.microsoft.com/Forums/en-US/winserverfiles/thread/cb62238c-b3d0-4989-b45a-ae6de6701a7b?stoAI=10
However its best suggestion is to use a product from AOMIE, but I tried that and it didn't even recognize the disk. It also suggests that one needs a better version of diskpart.exe and to try to the 32 bit version. Anyone have any experience with that?
I also tried creating moving the disk to Windows 7 x64, making it dynamic there, but when I move the disk back to 2K3 it does not recognize it, and goes back to a 2TB partition. I also saw something about needing a 512 block size for 2K3, but W7 does not allow anything smaller than 1K.

We do support 512 Block size on win7. Are these disks MBR dynamic or, GPT dynamic? For using more than 2TB try first converting disk to GPT and then convert it to dynamic. MBR has the known limitation of 2TB.
Do let me know if it helps,

To answer the question, they are GPT disks, that is kind of step zero in order to have a partition greater than 2 TB.
I was able to get the CMD version of Format to use 512 block size (GUI version is only 1k), but that turned out to be a six hour waste of time, since when I put the disk back into W2K3 it once again thought it was a non-dynamic 2TB partition, and then would not convert the whole disk to dynamic.
Still looking for a solution....

This bacause Windows 2003/XP do not support such configuration:
Any large-sector disks, such as 4K native, 512E, or any non-512 native disks, are not supported by Microsoft on any Windows XP-based version of the operating system.

This is not a large-sector disk, according to fsutil.
And according to
W2K3 SP1 does support drives greater than 2TB, and I am able to create a basic disk that spans the volume.
The problem is converting it to a dynamic disk, which is described as a bug at
its just that there is no x64 patch, which others have complained about also.

can you send me snapshot of diskmgmt.msc on both win7 & win2003? Let me have a look,

During my research, if found the following artcle which also mentioned a 3TB disk should be supported in Windows 2003 SP1:
Has anyone managed to get a 3TB dynamic disk on Windows 2003 Server?
So I contact the author about this issue. He said it could be caused if your hard disk is a 512e drive as the 3TB drives on the market today are normally 512e drives. However manufacturers stopping identifying this, and if the controller is old, FSUtil will not able to identify a 512 drive but recognized it as a normal 512n drive.
Thus please provide the drive model so we could search on manufacturer's website for exact information.
Also please paste the screenshot in your reply which Satish mentioned if available.
