So, I decided to start a whole new thread for this. Enjoy!!!!!

Install Marcrium Reflect free and make a complete disk image onto a USB stick.

Dissable fast startup: Doesn't come out of shadow Mode on restart.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power]

GUI wont start:

start a command prompt as an administrator then type the following command and press Enter:
reg add HKLM\SYSTEM\CurrentControlSet\Services\diskpt /v Control /t REG_DWORD /d 268435456 /f
Reboot and try again.


Some research (googling, actually) let me to suspect that the retained shadows of the drive were somehow corrupt, so I simply deleted them (vssadmin delete shadows /for=c: /all). Since then, there have been no errors reported, new shadow snapshots were created and everything else is working OK.

Drive Z: Error:

In SD's admin section, (administration) Click More Details. Where it says Others, change that from 200 to 1

Check for drive errors on reboot coming out of Shadow mode:

Here on my system, Win 11 Enterprise, I tried all the check disk options along with all the great check disk third party Apps along with the HD manufacture software. None of that worked and so I can only run using RAM.
RAM used as write cache on my system is set to 1000
