Chkdsk Access Denied Elevated Mode
Become a and go ad-free! Checking a diskFiles on your live in folders; folders can live in other folders; the whole mess lives in your disk, which might actually be a on a larger hard disk. On top of that, there may be security information about who is allowed to access what and in what ways they’re allowed to access it.As you can imagine, things get pretty confusing. All that you probably care about is that you get what you expect when you access a file.There’s a lot of information on the hard disk to help keep track of all of the data that’s being stored there. CHKDSK’s primary job is to make sure all of that administrative information about the files, folders, and other stuff stored on the disk is correct.Normally, all of that information is correct.
Right-click on CMD and click on run as an administrator and then run chkdsk. You can also disable UAC. This posting is provided 'AS IS' with no warranties or guarantees, and confers no rights. C: WINDOWS system32 CHKDSK Access Denied as you do not have sufficient privileges. You have to invoke this utility running in elevated mode. You’ve not run Windows Command Prompt as administrator. Oct 15, 2018 The error: Access denied as you do not have sufficient privileges. It is quite annoying that when you want to do some operations to your disk like run CHKDSK in Command Prompt only to get the return message: Access denied you do not have sufficient privileges. You have to invoke this utility running in elevated mode.
The system is designed to keep it correct from startup to shutdown.Unfortunately, a variety of errors can cause it to be incorrect — things like not shutting down your computer properly, removing USB devices without using Safely Remove, or just flat out hardware errors can cause problems in the administrative information on the hard disk.CHKDSK’s job is to try to repair those errors. What’s a ‘command line’ tool?Most programs in Windows appear as well, as (or in) a window.Command line tools do not.
They don’t know about on-screen windows and don’t display their results in them. They rely on the Windows “Command Prompt”, which is nothing more than a non-windowed environment that mimics the days before Windows, when all programs were “command line” tools under MS-DOS.To run CHKDSK, we start with a Command Prompt. Running CHKDSKYou’ll find Command Prompt in your Start menu. In Windows 10, right-click the Start menu, and it should be listed right there. You’ll want the “(Admin)” version so it runs with full administrative privileges. Command Prompt (Admin) in the Windows Start menu.You may instead see “Windows PowerShell” instead of Command Prompt. PowerShell will do for our purposes.
Once again, be sure to run the “(Admin)” version.In prior versions of Windows, you’ll find Command Prompt under All Programs – Accessories, or by searching for “Command”. Make sure to right-click on the entry and select “Run as Administrator”.Running Command Prompt will open a new window that looks like this: Windows Command Prompt.Command line tools are run by typing the command and pressing the Return or Enter key.
Any output the tool generates shows up in the window below your typing. Running CHKDSKTry it now: after opening a Command Prompt window or clicking it to make it active, type CHKDSK followed by the Enter key.If you see something like this: C:WINDOWSsystem32 CHKDSKAccess Denied as you do not have sufficient privileges.You have to invoke this utility running in elevated mode.you’ve not run Windows Command Prompt as administrator. Close Command Prompt (either by clicking the “x” in the upper-right of the Window, or typing “exit” followed by the Enter key), and start it again, this time being sure to select the “(Admin)” version listed, or right-clicking on the Command Prompt menu item and selecting “Run as administrator”.Without any parameters (I’ll describe a few in a moment), CHKDSK does nothing more than check the disk. The special case of C:C: is special.
(More correctly, your system drive is special, but in most cases, that’s C.) The problem is that your system is using C:, and CHKDSK can’t repair things that are in use. Run CHKDSK /F on drive C: and you’re likely to see this: Attempting to run CHKDSK /F on the system drive.Answer Y for Yes and then your system. CHKDSK will run before Windows starts so it can repair the drive before Windows starts using it. Common usageThe most common ways to use CHKDSK are:. CHKDSK /F – to check and fix the current drive (a reboot might be required). CHKDSK D: /F – to check and fix a specific drive (in this case, D:).
CHKDSK D: /R – to check, fix, and look for bad sectors on a specific driveYou can also run CHKDSK /? To get a list of additional options. More for Patrons of Ask Leo!have access to this related video from. Chkdsk checks your disk for errors at a low level, requiring exclusive access to the disk to do so. 'Chkdsk cannot run.'
Means it doesn't have the exclusive access it needs. The Windows system utility CHKDSK is a powerful and useful tool in diagnosing and repairing certain types of disk problems. I'll review several ways to run it, and try and describe what it does. If CHKDSK freezes when you run it, you may have a problem with your files or hard disk. But don't blame CHKDSK for the problem.
There are times when the disk checking utility needs to run before you boot into Windows. Sometimes it seems to get stuck and does so every time.Posted: April 22, 2019in:This is a minor update to an article originally posted May 18, 2011Shortlink:Tagged.

ENTER key & RETURN key mean the same thing.now., as in.today.I’m old enough to remember when the term was CARRIAGE RETURN & LINE FEED.
Even the key was labeled CRLF. This harkens back to when terminals were more like typewriters (actually teletype machines). This predates PCs by decades.If you look carefully at the ENTER key on most keyboards you will see an arrow and the tail of the arrow actually has a vertical component; which represents “go down and to the left”; just like the function on a typewriter.
Running CHKDSK /R may take some time. I have several computers. One is a desktop running Windows XP Pro w/ SP3 — I use some legacy peripherials — with a 1.9 GHz processor and two sticks totalling 2 GB of RAM, and having a C: drive consisting of a 80+ GB hard drive (60% full) and a D: drive consisting of an “old” IBM 18 GB hard drive with SCSI interface (80% full). I recently have run CHKDSK /R on both drives. NOTE: given my system, to check and repair all sectors on the C: took 11 hours.
I was surprized. So, if your system seems to run “slowly” using CHKDSK /R it nevertheless is probably doing its job. Just enjoy a movie or two. Jim,I won’t speak for Leo and I’ve personally not worked with Win7 yet but I can say that XP will spring a chkdsk on you from time-to-time.
I can’t say I’ve seen it after an update, but it’s always after a reboot. It boots to a cartoonish looking light-blue screen with a simple looking Windows logo and simple text that explains breifly what it’s doing and it’s progress. Furthermore, after it’s done you won’t see it’s results until you go into Control Panel Administrative Tools Event Viewer and look up the scan results (I forget right now what the event source/ID is)HTH,Gabe. coffA few years ago, I had a file that I wanted to get rid of, but couldn’t delete under Windows.
It was at the end of a long path, and I had deleted or moved all the other files and folders along that path, but this file WOULD NOT GO!Eventually, in DOS, I managed to kill it – probably by using Norton!I then discovered that my entire “My Pictures” folder had disappeared!Well, I knew all the files were still there, and that I just (!) needed to re-establish the directory structure.CHKDSK presented me with SEVENTY THOUSAND files, named FILE0001.CHK, etc. (in seven folders). I have that hard disk still, untampered with since.ANY ideas how I might re-assemble the pictures? No, of COURSE I didn’t have a back-up!
Silly question!. I’ll probably find the answer long after writing this, but I’ve started a chkdsk /f/r in safemode to happen during a reboot.it’s been half an hour and it’s only 12% through, but in stage 4 of 5.It has a 500 gig drive.So the question is really about the other drive, I have a 500 gig USB drive that I left plugged in.Is this dragging out all this time for the main 500 gig drive? Or is it wasting all this time while also checking the storage drive?(which is probably a good thing but I hate the waiting) I’m posting this from another notebook I have running (yea 1 computer being checked and I’m impatient with a 2nd one live and online haha)thanks!. I started running chkdsk /r from recovery console after my computer shut down after a power failure and would not restart (windows xp) – I get a blue screen with the error unmountablebootvolume displayed; I booted from a recovery disk and ran chkdsk /r from recovery console; this has been running for over 4 days now with the same message displayed on the screen:C:chkdsk rCHKDSK is checking the volumeCHKDSK is performing additional checking or recoveryIs this something I should stop or let it go? I have read comments online of chkdsk taking days to run but that was with drives much larger than mine; is there any hope that my hard drive is salvagable? In regard to your reply below to Jeff, I am not clear on the answer to his question.
Is chkdsk useful (or harmful) for SSDs? Please clarify.T/Y,Patp.s.
Thanks for all of your help. I always look forward to reading your article each week, and truly enjoy reading your comments.Jeff18 May 2011 ReplyIs chkdsk useful (or harmful) for SSDs? Supposedly (maybe I learned this on your site), SSDs wear down faster than HDDs and you are supposed to avoid doing things like defragmenting. So, should I also avoid chkdsk?The wear on SSDs comes from writing, which defrag does lots of but chkdsk does only when fixing things.Leo19-May-2011. I found that Ctrl+C doesn’t abort chkdsk /r while it is already in progress. I have yet to try Ctrl/Fn+Break, closing the command prompt window, or forcibly switching off the PC (as suggested by a user elsewhere).My concern is: Is forcibly aborting either the chkdsk /r or chkdsk /f process harmful to the internal/ external HDD in question?
Is there a risk of data loss &/or compromise to the file system?From an internet search, it appears that opinions differ somewhat as to whether terminating the said process is harmful, although it seems that many users (including the helpers at the Microsoft Help forum) advise against it. Hi I have been running check disk via properties - tools on my c drive window 7 to try to repair bad sectors on a 400gb hdd and it took about 5hr to do 80% and that was 2 days ago. It is still running very slowly and it is now at about 90%. I would like to cancel it.my question is if I cancel it now without it finishing will any bad sectors that may have been identified by check disk and would be marked as bad for the OS to recognize be retained by the system or will all that be lost due to canceling?I understand that the HDD has probably gone bad, but if you know the answer to the above question and let me know it, that would be much appreciated.thanks.
My HP media center shut down after loading Windows 8.1 desktop. Now it goes into “automatic repair” and fails to fix problem.From Advanced options I can bring up command promote and try to run chkdsk with switchs /r and /f but the computer just shuts down as soon as it starts running chkdsk.
Booted for USB recovery image and same thing. Trying it from x: “chkdsk c:/f or chkdsk c:/r but it just shuts down. It stays up out side windows, but running anything against the HD it shuts down. Will not boot into safe mode, but sometimes can boot into safe mode with command promote. Do you and suggestions?
My DATA disc with about 600 g has become corrupted and won’t open. It is recognised in BIOS and ‘this PC’ (I am running 8.1 Pro X 64).I bought a new drive and using a programme called ‘Backupper’ from AOMEI I got it to read the corrupted drive and run a backup which suggests that something was working. I then ran the RESTORE part of the programme onto the new formatted replacement drive and it restores OK.
Trouble is I now have 2 discs with the same corrupted data which wont open, I suppose that is not unreasonable. CHKDSK running as an Administrator says File System is NTFS and data structure is corrupted and unreadable. Any helpful suggestions please?. Yes, spinrite, written by Steve Gibson Is the best program that I have ever come upon.It is only at version 6.0 after many years since first version.
That’s as good an indicatoras any thing that the person that was writing the program. Know what he was doing.also its programed in machine code called assembly. It doesn’t need the be translatedinto the PC Machines code, so it runs very fast. I have version 6.0 and I have used it tocheck some USB Flash type drive that were saying can not write to disk as disk is read only.The cost is not very much, I don’t remember how much it cost so it was not very much.You also get the next updated version free I think.

Hello,I have a situation where the contents of several files have mysteriously disappeared from the back up section of my external hard drive (a plug & play Hitachi, that I bought about 4 years ago.
It still has plenty of capacity on it.I have seen the chkdsk remedy recommended by other users to solve my problem, and then I have followed you instructions to the letter, several times but I still get presented with the words “Cannot open volume for direct access”.this is despite having ensured I went for the Administrator selection.(I am running a new laptop with Windows 8.1).I would appreciate your help asap.to recover the contents of the files, the folders of which are named with their capacity in terms of bytes.Thanks. Hi,Windows is not able to boot up. I am using Windows 8.1.I have tried using system restore Option and tried a different date but system restore popped up with an error code and it stated that drive on C: is corrupted.
I have used chksk D: and chkdsk e: and it showed no issues. However I have not tried chkdsk R F.Will this fix the whole issue and will I be able to reboot windows normally.Is there any other options other than formatting as I wanted to troubleshoot with alternative ways.Please advise.ThanksShriram.
Is CHKDSK D: /R same as CHKDSK /R D:?2. If my disk have 2 partitions C: and D: on the same disk. In Command Prompt I am in C: now, I type CHKDSK /R, will it do chkdsk for C:, or will it do chkdsk for the whole disk both partitions C: and D:?3. If my disk have 2 partitions C: and D:, In Command Prompt what is the command to run chkdsk /r to scan both partitions C: and D:?4.
My disk is faulty, I still cannot access a file on my disk after running CHKDSK D: /R (it hangs halfway), would I be able to access the file if I run CHKDSK D: /F?Thanks. Cancelling Disk CheckIf chkdsk has started and for some reason (most likely taking too long, and you need access to your computer) you can stop it by running a command prompt. Open up an administrator mode command prompt by searching in the Start menu or screen for “cmd” and then right-clicking on the item and choosing “Run as Administrator”. Type in the following command, substituting the drive letter if necessary: chkntfs /x c:I used that command last week and it worked without causing me more problems with that external drive. I have since used another (seldom used) computer to re-run chkdsk on the error-ridden drive. The process took almost three days!
However, the drive now runs without problems. Leo,Since Windows 7 no longer boots on my computer, I used your article to run the CHKDSK command from the Windows Recovery Environment, which I accessed via my Windows installation DVD. But I ran into a problem.My Windows drive is C, so at the X: command prompt I enteredchkdsk c: /rThe message I got was“The type of the file system is RAW. CHKDSK is not available for RAW drives.”While disturbing, that message doesn’t seem inconsistent with other symptoms and messages I’ve seen when I try to boot and/or repair Windows (not related to CHKDSK so not appropriate to go into here). I thought I’d mention it here, though, since the message was generated after using CHKDSK.Any advice would be highly appreciated. At any rate, thanks for the clearest and most thorough explanation of CHKDSK I could find online.
I had forgotten the parameters I used to use back in the DOS days, and needed a refresher. I’ve been getting the BSOD since October (about sixty times), which I’ve managed to suppress it by logging out/back in every few days.I’ve tried just now to defragment my main drive and received a notice that “chkdsk” is scheduled and told me to run it. Not knowing what chkdsk is, I searched and came here.This command prompt is what my computer does before Windows starts, unless I cancel it, it does nothing that I’ve noticed. How do I unschedule chkdsk so I can run the defragmenter.Much appreciated, Leo!. I have a 2TB iomega was going good until we had a power cut then it kept saying i needed to format but i didn’t want to risk losing all my family photos and my files so i tryed the chkdsk g: /f/r it was going good but it seems to be still on stage 4 of 5 10%, it has been like this for the past 5 hours and not moved yet.
Was this the right thing to do? I will leave it going while im at work hopefully it might be finished by then. If not is there anything i can do to make it move or have i done something wrong?. I’m having the same issue, or maybe not. I am having some issue and i thought i would try your fix.
Access Denied When Running Chkdsk
I have a toshiba portable hard drive when alot of movies on it. Suddenly, computer wouldn’t read it and gave me the message to reformat it. I’m running the chkdsk j:/r right now. It seemed to be running fine. It got to 33 of 2560 file records without a problem now each one is “unreadable” i’m at 103 now. This seems like it will be a long process.
Is my hard drive toast? Am i wasting my time?side note: the usb wire has had a little bit of a short for some time.
Coulde that be the cause of my problem? Also, is there a chance that the actual hard drive is fine, but the connector electronics inside the case are the problem.it just skiped from file 115 to 120. Does that mean 5 files were good?. My laptop crashed a few days ago while writing to an 8Tb external HD that had about 540Gb used. At the time I ran chkdsk from Windows Explorer, but the progress bar showed no progress or action even after many hours so I canceled it.
After reading this posting I doubt that it stopped chkdsk, probably the cancel button was just to close the window as if one had decided to not start it. I have since shut the computer off several times. I can now read, but not write to the external HD (says it is dirty). I am now running chkdsk D: /r /v from the command line window. I noticed that the HD is now showing as exFAT, which probably just means it’s not FAT, but I am pretty sure that before it showed as NTSF. Should that be a concern? I also am concerned that is will take a month to complete.
It is been “verifying files and folders” for about an hour with no updates. Hi Leo,Could I have some advice please.
I have removed Mcafee a/virus from two laptops and replaced with Total Av, on one laptop this has worked well on the second laptop, I installed Total Av, without realising that I had not fully deinstalled the Mcafee version. Total Av deinstalled, then Mcafee removed, laptop rebooted, Total Av reinstalled, but noticed the realtime a/v feature was not enabled. I got a message saying that ‘intel storage device has to be disabled’ before realtime protection would work.
Followed steps, went into Device Manager and ‘IDE ATA/ATAPI controllers’ and removed using a driver utility removed the ‘Intel driver’ which was replaced with the ‘Standard SATA AHCI Controller’I have done a CHKDSK check via Command Prompt (Admin) and these checks across the drives have stated ‘ zero bad sectors’, assuming now that sectors are ok, what could be stopping the Total Av realtime protection from working, as I am still getting the message ‘intel storage device has to be disabled’. Any thoughts? ( advice appreciated) thx. A very thorough and quite comprhensive article, Leo. I am glad that I took the time to fully read through it- even the boring stuff I already knew.However, you did fail to mention an important point re the agenda of Command Prompt.First, be it known that I have my CP on the top level of my Start screen aps (I run an HP Pavilion 110-220 desktop PC w/ an HPw1907 19″ monitor screen using Windows 8.1 OS) so it is always handy for easy use. I always right click, hit Run as Administrator and then hit the OK for permission to run as you have said as administrator. Next I left click CP and get the cool black w/ white text DOS screen.I next input all the crapola CHKDSK whatever I am gonna run and hit Enter.This tells me that CHKDSK cannot run any checks while it is in use and would I care to srt up a CP run for the next time I reboot/restart my Henrietta, my PC?Next part confused the devil outta me.
At the end of this line appears and no other explanation. When running CP the mouse cannot be used so one must place a Capital Y or N at the end of that line and hit Enter.Presto!
You get a pleasant message from old CP that he/she (One must be politically correct) that your CHKDSK task will be performed the next time your Henrietta (Or whatever name you have given your PC) is rebooted/restarted.To check Memory, I usually have to wait for a prompt to use CP for a memory check from the PC itself. However, to run one yourself the next time you reboot/restart your PC, the instructions are easily found amongst your Control Panel goodies. Just search ‘memory test’ there or Google or Yahoo it to find the correct procedures.A word of warning for any CHKDSK ops- They can seem to take forever and you cannot use your PC at all while CP is running those tests for ya! Memory Tests and there are 3 usually take about 2-3 hours depending on ‘how much junk you have stored in your memory banks, Pilgrim’ as my own fanfictional OC ‘CC’ is wont to say to folks. He is quite obnoxious.Hey Leo, a quickie for ya.
The CP screen is a DOS which predated Mac and Windows and the other OS goodies by many years. What does ‘DOS’ stand for. It could not be as simple as ‘Digital Operating System’ or could it? Have I perhaps just answered my own query? Thanks for listening to me rant and rave, my friends abd Leo.
The Keiman of Anime is very grateful for your assistance all these years, sir. Sayonara for now and have a swell week!. Command Prompt isn’t DOS, but it’s definitely modelled after the DOS interface. DOS stands for Disk Operating System. (MS-DOS Being Microsoft Disk Operating System, and IBM’s PC-DOS being Personal Computer Disk Operating System). In this context the “disk” being referred to was the original floppy disk.FWIW: Memory (RAM) tests shouldn’t be impacted by what you have “in” memory at the time, particularly if it’s performed at reboot. It’ll depend on how much RAM is installed in the machine.
CHKDSK will be impacted by how much you have stored on disk. Hi Leo – thanks for the article which prompted me to try it. CHKDSK /F found and fixed an error.
But when I tried CHKDSK /R I got the expected “run on restart” message, restarted, and it got as far as 15% then stayed there for over 6 hours. I see other messages that it can take some time, but sticking on the same number that long – is that usual? I didn’t know what to do, as I needed to use my PC, so I’m afraid I resorted to switching it off, wait a minute, switch back on (having read other responses I can see that what I needed was Cntrl C!) I’m now reluctant to run it again in case it hangs again.Any thoughts? Thanks, Helen. I decided to run a CHKDSK (ScanDisk), but when the computer rebooted I got an error message.
It went by so quickly I never got the actual number of the error. It said the CHKDSK couldn’t run because some “recently installed software” was preventing it from doing so. It wanted me to go through a system restore to get it back to a point where the scan could be free to run.Well, I don’t know what the message meant by “recent.” Since I haven’t run the scan in 8 months+, maybe it means “since the last scan.” I don’t want to put the two user accounts on the PC through the inconvenience of however many system restores it would take to finally just to allow for the scan. Is there a safe, reliable, free alternative to the (Windows 7 Pro) built-in Scandisk feature that would do the same thing, including making any repairs?Btw, I don’t know what software the error message could be referring to. A Palemoon update? A Vivaldi update?
CCleaner update? A Windows update? I don’t really have any brand-spanking-new software that I’ve gotten in the last few months.Any suggestions, including, as I say, any alternative scan to run, would be most appreciated.Thanks!

Right-click on CMD and click on run as an administrator and then runchkdsk.You can also disable UAC.Unfortunately, this solution doesn't work. On a completely new system chkdsk doesn't run.I clicked Start and entered cmd in the search, right clicked and selected 'Run as administrator' and yet fails with an incorrect error message. Next I create a shortcut to cmd.exe on the desktop and in its properties page, on the Shortcut tab,I pressed the advanced button and clicked 'Run as administrator'.
Double clicking and running 'chkdsk /F /R /B F:' still gives the incorrect error message.(I would have included the screenshot, but Microsoft won't allow it).
