Command Prompt to Repair Disk

I found this page when searching for a solution to my BSOD:

Can you open Elevated Command Prompt from Command Prompt?

I started following zbook's instructions but got immediately confused because for the C Directory it showed my D drive (which I read elsewhere is to be expected) but then the D Directory is not my C drive so I stopped, created an account, and here I am. If booting from a USB are these directions applicable?

No drive was recognized. I assumed to leave it on D: and this is what it says:

D:\>bcdedit /enum
The boot configuration data store could not be opened.
The requested system device cannot be found.

D:\>bcdedit |find"osdevice"
'find"osdevice"' is not recognized as an internal or external command, operable program or batch file.

So I went ahead and proceeded with zbook's steps. I've pasted the steps I'm now stuck at. I don't have any volumes that display RAW as per step #21, so I don't have a drive letter to enter for step #24.

21) type: list volume
(look in the column Fs for any volume that displays RAW instead of NTFS)
22) type: list partition
23) type: exit
24) type: chkdsk /f /r G: (change G to the drive letter of the volume displaying RAW)
It may display "The first NTFS boot sector is unreadable or corrupt."
This may then convert the RAW volume to NTFS.

I have four HDD in my pc so I was having a hard time figuring out which one to run chkdsk on, so I unplugged three at a time. On the second attempt, I guessed it was C and ran chkdsk, but it said "Chkdsk Cannot Run Because the Volume Is in Use by another Process. Would you like to force a dismount on this volume windows 10?" I was searching for what that meant and I found I could identify the correct drive letter for my Windows installation by typing:
dir C:\Win*
dir D:\Win*
dir E:\Win*
until I found the Windows folder.
Upon restarting to try and do that, everything came backup like normal.

Is there something else I should/could run now to see if one of my HDD is failing?

Btw, thank you so much for your assistance.

Wow! Thanks. Clearly I'm having problems. I've attached a picture. My C Drive (with Windows) is Yellow. That's the one I included as a picture. V Drive is storage. I'm assuming I should replace my C Drive.

You have just one Reallocated Sector and 16 Current Pending Sectors. That does not of itself mean the drive has to be replaced immediately, but it needs watching closely. Should either of those counts increase then it is a probable sign of immanent failure. However, your 51,589 powered on hours (nearly 6 years) suggests it's near the end of its useful life.

I have a machine (the one I'm typing this on) that has had just one reallocated sector for (to my knowledge) the past three years. So far it has stuck at just the one, but I regularly make a system image so I'm prepared to replace it should it get worse. At nearly three years powered up I'm curious to see just how long its original HDD can continue to work.

I have another machine that had hundreds of reallocated sectors on its HDD (and the count was steadily increasing). That one got a new SSD before it was too late to rescue.

I'm backing up stuff now to one of the other drives. Since I've already had the BSOD I'm going to replace it. My other V Drive has been powered on for 91,906 hours, and the D Drive just as long as the C Drive. I'm assuming C is failing since it has Windows and programs. V Drive has Reallocated Sector Count of 5 under Raw Values. Thanks so much to everyone who helped!!! I'm going to Mark as Solved, however, if there is anything else I should do, please advise.

Probably for the best....

It's use that wears out a drive, some drives also report 'Loaded Hours (DE)' which is a better measure of how hard a life it has had. Powered on hours can be high, but if the actual hours of use are low in comparison the drive should have life left in it. Reallocated Sectors are always a warning sign though.
