Greg,
Thanks for your knowledge. I will file this away for later.
Will simple tools appear in time so that we may know whether
our 'getting huge' EM drives and already huge SSD drives were
setup and/or formatted?
Best,
Duncan

MBR can only be used as the partition table for disks not exceeding 2.2
trillion bytes in size (technically, it's a limit of 2^32 sectors, which is
2.2 trillion bytes using a standard 512/512e HDD). Once you cross that
boundary, you need to use a different form of partition table - the GUID
Partition Table. UEFI enters the picture because a UEFI system is required
to boot many operating systems--including Windows--from a disk using the GPT
layout.
I general, I recommend that disks under 2.2TB that are not expected to grow
to that size continue to use MBR for better compatibility. Switching to GPT
is a destructive process to any existing data, so it's a decision that is
best made when the drive is first initialized.

Greg,
While I feel bad for @jjoeuser, I'm now curious about the diffs between MBR
drives and GPT drives.This thread shines light on something new based on
'EFI Bios.'
As I upgrage my PC's am I creating GPT drives???? If so, and they work,
Fine. Just wondering what I may be doing.
Thank you for your experience.

I'm not at all suggesting that it didn't happen; I'm just making sure that
the rest of the collective knows that this is a freak incident and that it
is not a requirement to do anything special in disk management or otherwise
when moving a GPT disk. I've worked with a lot of GPT disks many different
hardware and operating system configurations--I'm quite certain I would have
run in to this if it were a common occurrence. The root cause for the
behavior you experienced is, at this point, a mystery.
If you have information from an official source prescribing that a GPT
disk be unmounted before powering down (if you're removing a disk live it
should always be removed cleanly, GPT or otherwise) and relocating, I'd be
interested to see it, as I've not yielded anything.

Well, I'm very glad for you, I'm also lucky in the fact that nothing there
was to critical and/or can be transferred again.
However, this did indeed happen. I also looked up the info as I have
described to everyone & that is a fact. The only other thing I can think of
is, I went from an internal sata port to a USB3 ext sata cable?
Regardless. If you have a GPT drive - UNMOUNT/REMOVE from DISK MGMT! If
you forget, DO NOTHING - plug it back in where it was & then
REMOVE/UNMOUNT... This may or may not apply to UEFI - I don't have UEFI & I
don't care to right now.

joeuser - Still looking for the 'any' key...

I don't think that's it--I've moved UEFI to UEFI, BIOS to BIOS, and BIOS
to UEFI.
