Windows 10: Disk Partitions different in Win10 and Win8.1 ???

So here's the thing.

I have an SSD which I have removed from one laptop (it's running Win8.1Pro) and connected it through a USB caddy to my other laptop (running Win10Pro 1909) so that I can move some data around.

To do this I shrink the "C" partition on the SSD and create a new partition from the empty space (shown as "E" in the screenshot below) in disk management on the Win10 laptop. I then copy around 200GB into this new drive, some from the Win10 laptop drive and some from the SSD "C" drive (shown as "D" in the screenshot).





Now when I reinstall the SSD into the original Win8.1 laptop there is no new partition and it's as though nothing has happened to the disk, see below.





When I put the SSD back in the USB disk caddy it shows up as the partitions in the first screenshot.

What's going on?

Running Win10 pro clobbers Win7 hard disk

Obviously I have to be more detailed about the configuration:

All my desktops and notebooks have the same configuration:

4 partitions, named Boot, Application, Data and User Data.

Step 1: To be able to test Win 10 I made a 1to1 copy of my Win7 hard disk to another hard disk and disabled the original installation. After that I made an update from Win7 Ult to Win8 pro on the copied disk, as mentioned I have three Win8 installion packs
bought but never used it after testing!

Step2: Downloading Win 10pro and upgrade the Win8 installation, all this takes time but Win10 worked as expected.

Step 3: Enable in BIOS hard disk with Win7Ult, reboot win10, 2nd hard disk is correctly recognized and Win10 is working.

Step 4: Switching off hard disk (already in an switchable environment) with Win10 installation and reboot hard disk with Win7Ult, error message shows up, that the partitions have to bee checked!

I hope this will clarify the subject

Disk management console view is not up-to-date

i dont know how to fix your disk management, but i can fix your partition problems...




open up Command Prompt with admin rights. (Right click, run as admin)


enter in
DISKPART
list disk

then find the Disk number for your Raid array... lets call it number 7 ( you can tell what disk is what by the total size)
type in

Select Disk 7
List Partition (will give you a list of all the partitions..)
Select Partition 1 (im assuming you only have 1 partition on Disk 7) repeat this step if you have more partitions.
ASSIGN


that should get the array up and running ready to use.


EDITED.

any problems, post back ^^


Still EDITING *Stick Out Tongue

side question, have you tried restarting the PC?
