Windows 10: My secondary HD can no longer be seen by disk management.

My secondary HD can no longer be seen by disk management but can be seen by device manager. Not sure what happened but I'm running out of ideas regarding how to correct the situation without buying a new HD.


Thanks for any help you can provide... Al.

Windows 10 1909 Causes Secondary Hard Drive to not be Recognized

Installing the Windows 10 1909 Update causes my secondary hard drive to not be recognized.

Steps to confirm issue:

• Secondary drive not visible in Windows Explorer
• Secondary drive not visible in device manager
• Secondary drive not visible in disk manager

Steps to replicate issue:

• Installing 1909 update

Steps to resolve issue:

• Uninstall 1909 update

Since updates can only be delayed for so long, an actual fix would be appreciated.

 

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?

 

Cannot Format HD


Need to initialize it as GPT disk type with HD > 2TB:
From Admin command prompt:

1. diskpart
2. list disk =====> Take a note of disk # for the 4TB HD
3. select disk # ====> From step 2
4. clean
5. exit

Open Disk Management and initialize the disk as GPT, create simple then format.
