Post by Robert in CAI have my 6 TB hd and now just waiting for the case.
Then I'll try cloning it.
Here's your instructions for cloning but as I say
they have automated the mrimg backups allot so I
think it may be the same with cloning.

It's interesting you looked up Righteous Warriors,
It was started by someone I use to know and I was
surprised it still was up. I tried contacting him but
never got a reply.
I barely am understanding you with the IPV4 and
IPV6 addresses. I'm trying to follow along.
Is there anything you want me to do? Run any
tests?
Thanks,
Robert
The reference to "somesite.com" was similar to "example.com",
just to show you the format.
Not to actually go there.
I wanted you to type a domain name, "example.com" or
whatever domain you're trying to use.

These links may point at the Macrium cloning disk instructions.
One of these links should work.

As it turns out, your request to "just clone the 2TB bootable backup drive
to the 6TB drive", this is a bit more complicated than expected :-)
You see, your previous backup drives (with their boot OS on them),
they were 2TB drives. That wasn't by accident, by the way. I am
a schemer. A schemer who hates surprises.
You can take the new 6TB drive, make it GPT
(GUID Partition Table, instead of MSDOS MBR partition table type),
and then in Disk Management, you can define the entire
6TB drive, as one partition.
That works fine.
The money is not wasted, because, you can use the *entire* drive
for backups. No problemo. When it asks what flavor of partitioning
you want, a 6TB drive works best with "GPT".
The problem comes, when you try to fit the older OS image you've
got, onto the 6TB drive. Remember that MSDOS MBR partitioned disks,
they work up to 2.2TB, so a 2.0TB disk was a "perfect fit for the job".
The MBR only has enough address space for the 2TB drive. It cannot
access storage above that point. There are two "hacks" for turning the
space above 2TB, into separate virtual drives (Acronis Capacity Manager
is one of the methods), but these are not practical. I used to run that,
but I got rid of it, because it was making me crazy.
If the disk is made GPT, and we want to boot the OS, we have:
UEFI GPT <=== most users do this. The OS installer does this
It is unlikely the Optiplex 780 has UEFI. I am
unable to confirm whether A15 BIOS update for the 780,
actually has UEFI option in it.
CSM GPT <=== this can be done with a Syslinux replacement MBR,
plus setting a GPT attribute bit, to support legacy
"boot flag" or Active flag, but in GPT-land.
https://superuser.com/questions/1750366/boot-a-legacy-bios-os-on-a-gpt-mass-memory
https://mirrors.edge.kernel.org/pub/linux/utils/boot/syslinux/Testing/6.04/syslinux-6.04-pre1.tar.xz
"You can install the Syslinux MBR boot code (gptmbr.bin), which behaves very much
like traditional MBRs that jump to an active partition's PBR, but understands GPT
partition tables and looks for a similarly named GPT attribute flag. (Specifically,
it checks bit 2 which gdisk calls "Legacy BIOS bootable.") The rest of Syslinux
is not needed."
You will notice this article,
https://wiki.syslinux.org/wiki/index.php?title=Mbr
does not address setting the GPT Attribute
in order to make gptmbr.bin to jump to the correct partition. You can set
some GPT things in Linux, which is what the previous paragraph proposes.
But "diskpart.exe" utility in Windows can also do that, and I've already had
to repair one GPT Attribute in the past using that.
You can help, by taking a screenshot of Disk Management (diskmgmt.msc)
of the 780 2TB bootable backup drive, to help me verify I'm preparing
my new recipe properly.
I hope by doing it this strange way, I will *AVOID* asking you to:
1) Flash update the Optiplex 780 BIOS. I don't want to do that.
It is unlikely to help, and I can't verify it would help.
2) Use the Microsoft MBR2GPT.exe utility. If you have your Win10 you installed
to get the Win10 license, there might be a copy of MBR2GPT.exe on there.
I don't really want to do that.
Instead, the steps will likely involve.
1) Macrium Reflect clone of Win7 C: and System Reserved, to the 6TB disk.
2) dd.exe transfer of 440 byte "gptmbr.bin" binary file, to the MBR sector.
This leaves the 0xEE protective partition single entry in the partition table, alone.
3) A diskpart session, selecting the currently active partition, and
making it active by setting GPT attribute to 0x4 or so. It'll be
something like that.
4) Test boot of the new setup, to see it vectors based on the GPT attribute it finds.
The reason the GPT attribute must be set, is the traditional 0x80 boot flag
has no equivalent in GPT-land directly (the same way as before).
Anyway, post a screenshot of the 2TB backup drive in Disk Management
(not file explorer), so I can have a look at it. In Windows 7,
Start : Run : diskmgmt.msc will give a nice clean picture.
