Windows 10: All HDD's inaccessible after reboot

Rebooted my Windows 10 machine today, now all of my HDD's are unreadable

- 4 internal HDD's

- 3 External HDD's (one is a set of raid drives)

All of them were working fine until today. If I plug my external ones into my laptop I can read and see the data just fine. Booting up MiniTool Partition wizard on my machine I can see every drive, all of their labels, used space, etc.

Disk Management shows them all as RAW, file explorer says I need to format them to use.

I also have a Hackintosh on this machine, booting into it lets me see and read all the drives just fine. So it's specifically my desktop windows 10.

Using chkdsk, it reads the drives with their proper file system, name, etc. Using "/f" says it found no problems.

I don't see any updates available. I'm also not able to roll back as it says my PC was updated more than 10 days ago.

Version: 2004

OS Build: 19041.610



Anyone had this happen before? I have been googling for a solution, but I cant find anything.

HDD inaccessible

I have a HDD that is now inaccessible and would appreciate some advice before I take the next step.

My system has:
-main SSD (C which has the Win system and all frequently used programs.
-secondary HDD (D which has all data and infrequently used programs.

Briefly here is what has happened and what I have done:
-about 2 days ago, the D: drive occasionally became very slow to access and eventually froze File Manager. A reboot would restore functionality for a short while but the problem would return.
-I ran an "error check" on the HDD. It found and fixed errors but the above symptoms continued.
-I ran a "chkdsk" on the HDD. It found and fixed errors but the above symptoms continued.
-Ultimately, the D: is totally inaccessible. It does not appear in File Manager
-Checking "Disk Management", the HDD is shown as "Disk 1 unknown" and it gives me a window asking to initialize the HDD as either MBR or GPT.
-When I boot the computer, it used to boot in less that 30 seconds. Now the POST seems to take forever before proceeding to boot.

I'm inclined to initialize the HDD but I'm worried that this will delete all data on the HDD. (I do have a back up but it doesn't include hundreds of irreplaceable pictures from a recent vacation.)

Any advice before I proceed and screw this up any further?

Hi Johan,

It is possible that your

causing the error message to appear. We recommend that you perform these troubleshooting steps and check if there are any changes:

• 
  Shutdown

• 
  Unhooked
  the
  HDD
  and

  PC.
  
• 
  Reconnect
  your
  HDD
  and
