Can not mount old Gateway Boot / File Drive in New HP

My old Gateway failed.

Today I purchased a new HP Pavilion 570-p023w​.

It sees my two USB 1 T drives straight away.

I put the old Gateway boot/ file drive a 500 gig Seagate Barracuda Sata in a Rrosewill RX308.
external USB enclosure.

The HP does not recognize it.

What do I need to do for mounting the Gateway?

Something at the Administrative Command Line?

H-E-L-P PLEASE.

I so need to be able to access the files on the Gateway Drive

Thanks.

A fellow at the library mounted the drive using the same enclosure so I know it works. I am trying to replicate his procedure.

The drive does not show in the partition manager or in the AOMEI Assistant. However Windows 10 beeps when I plug it into the USB port. So I am confused.

Here is the report from Disk parted.
DISKPART> list volume



Volume ### Ltr Label Fs Type Size Status Info

---------- --- ----------- ----- ---------- ------- --------- --------

Volume 0 F DVD-ROM 0 B No Media

Volume 1 C Windows NTFS Partition 118 GB Healthy Boot

Volume 2 Windows RE NTFS Partition 980 MB Healthy

Volume 3 Z FAT32 Partition 260 MB Healthy System

Volume 4 D DATA NTFS Partition 919 GB Healthy

Volume 5 E RECOVERY NTFS Partition 11 GB Healthy

Volume 6 G Removable 0 B No Media


Volume 6 was established in the library demonstration.

Here are the instructions he gave me.

One last variable.
The demo ran on my Gateway. Something went wrong with it. It appears the RAM has gone faulty. I am trying to source replacement memory.

Now I am running on a brand new HP.

Thinking about this a bit more I think the G drive assignment carried over from the Gateway to HP, so the HP somehow see it?

If so then the issue becomes how to mount it?


I tried doing that in Computer Management but did not see any mounting tools,

Then I found this page:
https://docs.microsoft.com/en-us/windows-server/storage/disk-management/assign-a-mount-point-folder-path-to-a-drive


Outtake
You cannot assign drive letters to boot volumes, or volumes that contain the paging file. In addition, you cannot assign a drive letter to an Original Equipment Manufacturer (OEM) partition, EFI system partition, or any GPT partition other than a basic data partition.

It seems like discpart should show all the partitions on the external?



So I am wondering how do I get past the boot partition for accessing the data?

Are there any other paths for getting to this drive?

I checked for the warning flag in Window Disk Management. None there.

I DO still see the folder for the G drive there and in Disk part
from DiskPart
Volume 6 G Removable 0 B No Media

So Windows recognizes the EXTERNAL USB drive, but not its contents.

When I disconnect the USB drive the folder goes away in all the partition managers I have tried..

I have tried other ways as I describe about but none are leading me to the files, like the fellow showed me at the library.

The mission remains discovering the missing step in this process that will reveal the files partition in the external USB drive.

This is not an issue with the brand new well+behaved HP Drive, so it does not call for a rescue disk.

But if there is a way to look at the external through a like program I am all ears. Post some links please.

Thanks for your responses and inputs Andre.

I get your drift for identifying / segregating a potential hardware issues,

Right now I need to put this down for a while.

I will report back when I have made some progress.
