Windows 10: Disk Management Is Seriously Misreading My Storage

I recently tried to uninstall McAfee from a brand new HP W10 laptop using the McAfee Product removal tool, but the uninstall quit partway through the process leaving me with half a program that couldn't run or uninstall either.
I didn't know what else to do so I finally reset my computer so I could start all over.
Unfortunately the removal tool failed and stuck again and I had to reset the computer again, only this time the Reset stuck at 40% completion. After waiting 2 hours it was still on 40% and not moving.

Finally I decided to shut it off and restart. When it started, it said "A configuration change was requested to clear this computer's TPM Module". It said press F1 to continue or F2 to not. I pressed F1, it rebooted and started up.
I downloaded Revo to get rid of McAfee and finished setting up the computer.
The computer has been running fine since then.

But here's he problem.....I have a 1 TB SSD and I just discovered that Disk Management recognizes 940GB capacity but it says there's only 16GB free, and that is totally impossible.
Speccy (Piriform Software) agrees there's 940GB capacity but says only 2% free space. What's going on?
I have no games, very little music and nowhere near that much software.

The computer thinks I'm using 98% of my C Drive and I'm only using a small percentage! What happened?
I'm sure there's a connection with what happened with that reset, but what do I do now?

Cannot find the D drive in regular places.

Hi

I have a problem with my drives. I literally just purchased this laptop and within one week the D drive is missing from file explorer, doesn't appear in disk management (even as unallocated). It does appear under the device manager, Intel rapid storage technology
and even in manage storage spaces under a pool. I've tried rescanning the drives, updating drivers (they are up to date) installing repair software. The only thing I can see as different is under intel rapid storage technology it states system disk as no (seriously
have no idea if this is even relevant)

Specs:

MSI GL62M 7REX

WINDOWS 10

1tb hdd, 128ssd

any help with this issue would be appreciated

 

Crash when Adding Storage Space

Hi All,

Windows 10 crashed with an exception when I tried adding a new disk as a storage space. I had made the mistake of not adding the new disk to my system through disk management first before trying to add it as a storage space. The issue now is that I cannot
see my new disk listed in disk management nor does the disk appear under the storage space pool. If I go into device management, I see the disk driver for my missing hard disk listed in there, the disk also shows up in my CMOS settings. What now? How do I
remove this disk from the storage pool so that I can have it back as a stand alone disk? I have tried deleting the hard disk drivers and the ATA controllers to no avail.

 

Hi, suggest you start with this to check your file system's integrity:

From an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Make sure the result is clear or fixed- else do not proceed.
Post back the result, which you can get after a restart as follows:
How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

Then download and run Ccleaner (free) - recommended - just leave everything default and let it clean temporary files and clear your recycle bin.

Recheck space used using file explorer.

Then download and run Windirstat (free) and post a screenshot of what that says (the scan will take a minute or two).

When this shows the pretty coloured picture of your space usage, mouseover or click on the three largest blocks or areas used and identify them.

Also please post a screenshot of Disk Management, and your system restore settings:

 

Thanks for the come back dalchina. It wouldn't perform the chkdsk. Here is what it said:

C:\WINDOWS\system32>chkdsk C: /F
The type of the file system is NTFS.
Cannot lock current drive.

chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts?

I didn't have any programs open, unless it's complaining about Kaspersky running in the background or some other background process?

 

You are booted into that drive, therefore it is in use. That is what it means by "another process".

 

If you say "Yes", it will schedule a chkdsk to run when you reboot the PC, before Windows starts.

 

Bree I told it Yes, shut down, restarted, it flashed a quick screen that said it would start chkdsk in 8 seconds, but then it didn't. It just booted up and went to the start screen as usual. Tried several times, same result.
So I went back to the Admin command prompt and scheduled a chckdsk C: without adding the /F at the end and it performed a quick scan of the C: Drive and produced a report that confirmed that I only had about 2% free space remaining on the C: drive and it stated there were no problems with the drive. GRRR

I checked Disk Management again and no change, but out of curiosity I right clicked the C: Drive in Disk Management and guess what I found.........the culprit!
A file, not a folder but just a TMP file labeled: Reset_SafeToDelete_OverwriteSpaceFile_0.tmp, and the size of this file is 878GB!

So Disk Management is not misreading my storage, it's actually there....878GB worth in just 1 file!
It's located in "This PC >Windows (C)" Everything else in this location is all folders except for this single TMP file.
I suspect I could just delete this monster file, but I decided to post back here about it first and get your thoughts.

 

I'd delete it - especially with a name like that.

If you google Reset_SafeToDelete_OverwriteSpaceFile_0.tmp that is what everyone else who got it did.

Run TRIM on your SSD after.

 

Well I finally went in and deleted the file "Reset_SafeToDelete_OverwriteSpaceFile_0.tmp" which was an 878GB file and everything appears to be back to normal. This ridiculous file somehow snuck in the back door as a result of that 40% Reset I mentioned in my 1st post. If you Google the name of the above file you'll find that my case was not the first, there's been a few others.
Out of all my years with W7 I never had any really stupid problems like that. A few problems yes, but not really stupid ones like this. 7 was a great OS. Leave it to Windows 10.

 

"Run TRIM on your SSD after"?
Manually? I thought that was performed automatically......how do I do that?

I have a Samsung SSD and they say all their SSD's are TRIM capable and I checked and my computer says TRIM is enabled. I hope so.

 

Go to Defragment and Optimize Drives and click on Optimize

It will do it automatically (eventually) but as you've just deleted a file that took 99% of your disk it is worth doing it manually just this once. It will carry on with its weekly schedule after that as normal.

 

Got it! Thanks Ix07, I'll do that.

 

You can tell it is set up properly for TRIM if it says Solid State Drive here...

 

Cool Ix!! Just did it. Thanks for pointing that out. I've never had SSD's before so I'm having to learn this stuff as I go.
Thanks again.
