System filecheck on C:

[ToddeSwe]

Hi

Now i've gotten more problems with my sons computer since yesterdays BSOD it scans the C: at startup but it can't fix the corrupted files.

When i made a chkdsk i got:

"

When i tried the suggested command "Please run chkdsk /scan to find the problems and queue them for repair." it couldn't allocate place for a shadow thingy...

How or what can i do to fix this corrupted files?

First time i run this scan i got the name of the files that was corrupted but not now, still when we start the computer it makes a autoscan on C: why is that?

what make/model is the C drive?
he has an SSD right?
open command prompt (admin)
type chkdsk c: /f and press enter
2 paragraphs will pop up, Press Y to agree to run it at start up
restart PC and let it run scan

/f = fix
if his drive was a hdd, you could use /f /r which is fix & repair but ssd don't have sectors so nothing to repair.

I am going to work out how to read dumps this week. I have to go out tomorrow but after then I give it a go

right click start button

choose powershell (admin)

copy/paste this command into window:

Repair-WindowsImage -Online -RestoreHealth

and press enter

Then type SFC /scannow

and press enter

Restart PC if SFC fixes any files as some fixes require a restart to be implemented

First command repairs the files SFC uses to clean files, and SFC fixes system files

SFC = System File Checker. First command runs DISM - https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/what-is-dism?view=windows-11

The Volume Bitmap is incorrect.

hope chkdsk works as there is a loop associated with that error that is tied to an error going back to XP

Redirecting

guess we wait and see. He might need to clean install Windows to fix the error.

If I read the data correctly, you have a 128GB SSD system drive, which has close to 120GB used—is that correct?

This may be a cause of various problems. While modern SSDs usually have some hidden capacity, I recommend you uninstall some big game before trying to fix anything further—give Windows extra room to breathe.

 

[Colif]

if he wants to play games off SSD, he needs a bigger ssd
128gb is getting a little small these days.
Better to aim for 250 or bigger

Otherwise, yes. More free space also helps as ssd run faster if they have at least 10% free space

Hi and thank you, i've tried this now and here is the results:

From the first command Repair-WindowsImage -Online -RestoreHealth it says when done:

Path :
Online : True
ImageHealthState : Healthy
RestartNeeded : False



Seccond command Then type SFC /scannow gives me:

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files and successfully repaired them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.

And here's the logfile:

When i restart it still tries to do the scan of the c: wich is a Samsung SSD 120 GB. It is just 60% full because i've told him not to install any games on it.

No it is just 60% full becuase it is so small i told him not to save or install any games to it.

Did you run chkdsk c: /f ?
if its still running it at start... it could be you need to clean install windows 10 to fix the error

So backup anything on the ssd he doesn't want to lose, put it on hdd
Clean installs not so bad if you not forced to lose anything. You can take time and make sure you have a list of programs to reinstall, or can look over files and make sure you copied everything. Its what I did 2 years ago when I got new PC and had to move everything across.
If he has any steam games, the games themselves can be reused on new install without need to reinstall them
I think same applies for other game clients too

unplug the hdd from data inside case (helps to unplug power before hand) - if the installer finds blank space on another drive, it has been known to put the boot partition on it, and if you remove drive later, it won't boot.

On another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB

boot from installer

Once PC starts fine from ssd a few time, turn PC off, unplug it and plug the hdd back into data again so your son can access files.

the upside to a clean install is it could fix that BSOD.

Yes i tried the chkdsk command and it is the same that windows runs every startup so now i just got 2 of them instead.

Can one use the built in reinstall windows without removing any files? Does it fix my problem?

 

[Colif]

No, because the problem is the actual file structure of the drive, resetting windows won't fix it. Only way is to remake it.
Resets just replace windows, they don't touch the underlying level

The Volume Bitmap is incorrect.

Now the volume is C drive
from what I can gather, the bitmap is used to track used and unused clusters on the drive (clusters are groups of sectors)
so it means it can't tell what space is used/unused

I help people with computer problems on Tom's Hardware and I don't think I ever seen that error before. I lost count of number of people I helped reinstall windows 10.
its unusual.

How old is the ssd?

Ok, then i have to make a new installation then. Will the inside command in windows do this under the choice erase all? Or how do to make a format of the c: before the new windows?

The SDD is my old one and i think it is about 3 years...

 

[Colif]

clean install of windows includes a format of the drive so no need to do it first.

3 years isn't that bad but 120gb drives have less extra space on them for error correction

what make/model is drive? most makers have software you can use to check drive. Makes sense to check drive before installing on it. If you tell me what it is, I go see what I can find.

it’s a Samsung sad 840

I removed the Samsung software because in a bother forum I was told it slowing the computer down. Crystal disc info says that the drive health is good.

 

[Colif]

it has a habit of running at startup, its not really needed to run all time.
still might help to run it anyway, just run diagnostics - https://semiconductor.samsung.com/consumer-storage/support/tools/
since you going to reinstall windows it won't make any difference now.

if its all good, install windows on it.

@Colif nice work here
Educational aside please:

and

it is just 60% full

Ignoring 1,024 not = 1,000, I read the first bit as 116GB total, 105GB used in files, and 9GB available. Iow ~90% full, compared to Todd seeing only 60% full—what am I interpreting wrongly?

 

[Colif]

Brian, could be part of this error

The Volume Bitmap is incorrect.
Windows has checked the file system and found problems.

Windows cannot tell what is free and not free. So if its reporting 60% full but actually 90% full, its going to have problems.
makes me wonder if trim was running on ssd. https://en.wikipedia.org/wiki/Trim_(computing)

You've right i must have been seeing wrong or remebering wrong... it was allmost full so i've removed some of it now.
