Windows 10 does not see one of my hard drives
« on: February 02, 2016, 06:16:03 AM »
I recently had to nuke and pave my OS driver for my home server as some form of Windows updates over time had been making it less and less usable to the point where it was easier to start fresh then try to fix things when only some aspects of Windows will work.

The 'new' OS drive is my older Intel 180GB SSD that I know works without any issues. I installed Win10 on it two nights ago and last night I finally had time to config the system. I never looked at the drivers before I installed DriveBender to re-pool my software raid, so that may be the original culprit. After this was done I had almost all my drives back in my raid, my 3 2TB and 1 6TB, yet my 4TB seems to not be found by DriveBender and CERTAIN software in Windows.

The BIOS and Device Manager both show that the 4TB HDD exists, the model, etc, however Disk Manager and Explorer do not show the drive. I have tried booting with just the 4TB and my OS drive yet DM and Explorer never display it. I know the 4TB was working prior, with great health as DriveBender periodically does SMART checks and alerts me of any drive issues. I was wondering if anyone has ever had a good working drive not be properly recognized by Windows in some aspect, but in others show up just fine. I'm hoping for some solutions that avoids me from nuke and paving the OS drive, if I have to do it I have no issues as it did not take long last time.

Notes(I know the high and mighty engineers might forget some of the basics so yah :P)
Always run cmd in administrator.

Try these steps:

Open Command Prompt. (CMD)
Type: diskpart
At the DISKPART prompt, type: list volume
Make note of the number of the simple volume whose drive letter you want to assign, change, or remove.
At the DISKPART prompt, type: select volume n
Select the volume, where n is the volume's number, whose drive letter you want to assign, change, or remove.
At the DISKPART prompt, type one of the following: assign letter=L
Where L is the drive letter you want to assign or change.


You can make L any letter as long as it is not already assigned to a drive.

Also worse comes to worse remove the drive throw it in another rig and confirm there is no other issues with the drive.

Turns out Diskpart was listing the disk as Foreign, imported it and all is good.

Technically your instructions wouldn't have worked as it Windows did not have the drive or partition flagged as active or online. I had to use the import function.
