Windows refuses to update past 1703

When they get unplugged, they come back up as different letters, and then he has to relink a ton of media and projects get messed up. Some I have assigned letters to, but I don't know if it always works. He usually is under tight deadlines and doesn't let me near his pc unless he has a problem.

But you've got that Disk mgmt screenshot you posted that shows what drive letters are used for each one. You can set them up again after the clean install because they'll almost all get reset by it.
Personally, I always give each drive a unique name [label] so I am never in any doubt about which one is which. You have done this for some but not all of your disks so I suggest you do it for every one of them before you do any disconnecting or clean installing. Drive labels do not get reset by a clean install [or by anything else that I've experienced].
One external drive is Invicta, another is Keint, another is Quips, another is Real, another is Supposed. I'll leave you to guess what their drive letters are. I only connect them when I need to.
I have all their contents backed up. My OS & internal data drives are backed up twice.


If, as I think you are saying, there are also some drives that cannot now be read then that can be addressed after the clean install. There is one particular forum member who has great experience of advising others in recovering many such drives.

Denis - he has so many drives because they are full of video. My husband is a videographer/editor. He works on many ongoing/recurring projects. We used to have a Acera Thunderbolt RAID Storage with his PC. Well it broke and none of the drives appear to even be formatted anymore. He lost 32TB of video. So now he just gets new external drives as he goes along.
He likes to keep footage for a while because it has saved him many times.... yada yada yada.

The Acera Thunderbolt RAID Storage is probably a Linux NAS. It is probably a RAID 1 (mirror) array. The information are still on the drives. You may access the information taking out the drives and installing on a Linux machine. You have to search to find out how do it. Win 10 can read Linux drives. That is subject for another thread.

Open device manager. IDE ATA/ATAPI controller. Do it mention AHCI?


It is missing the Intel Turbo Bust Manager Driver

I see I can download Intel Driver & Support Assistant. ITBM seems to be good thing?

Turbo bust dynamically controls the CPU frequency. Yes, it's good.
Run Windows Update. It may find the needed driver.

What do you have on drive 4 (H:)? Is it a OS or a data drive?
If it is a data drive we need to clean the EFI partition.

The ones that have names I'm sure were given to him by someone else.

Yes, many arrive with a label set by the maker.
My very first external HDD came with the name EHDD and as I was copying backups etc to it I found myself thinking of it as Eddy. So the next one was Fred, ...

They are only labels and they have no effect so he'll have nothing to fear.
But they can be examined by, for example, batch files. I use batch file scripts to do my backups and they start off with checking the names of connected disks then abort & warn me if the expected names for my backup disks are not found.


Best of luck,
Denis

To clean the drive 4 EFI partition (4.6TB)

Open a CMD window as administrator and type:
diskpart
list disk <- note the disk number of the 4.6T drive (it should be 4)
select disk # <- replace # with the drive identified above
list par <- note which partition is the EFI System partition (it should be 1)
select part # <- replace # with the partition number identified above
del part override
