How To Check Hard Drive Windows 7

Any time you have hard drive errors—or fifty-fifty strange beliefs you might not at first associate with a hard bulldoze—Check Deejay tin be a lifesaver. Here'southward a total guide to using the Check Deejay tool that comes with every version of Windows.

What Chkdsk Does (and When to Utilize It)

The Bank check Disk utility, also known as chkdsk (since that'southward the command you utilise to run it) scans through your entire hard bulldoze to observe and fix problems. It's non a terribly exciting tool—and running it tin can take some fourth dimension—but it can actually assist preclude bigger problems and loss of data in the long run. Chkdsk performs a couple of functions, depending on how information technology's run:

• Chkdsk'southward bones office is to scan the integrity of the file system and file system metadata on a disk volume and gear up whatsoever logical file system errors that it finds. Such errors might include decadent entries in a volume's master file table (MFT), bad security descriptors associated with files, or even misaligned time stamp or file size information virtually individual files.
• Chkdsk tin can also optionally scan every sector on a disk volume looking for bad sectors. Bad sectors come in 2 forms: soft bad sectors, that tin can occur when data is written desperately, and hard bad sectors that can occur because of physical damage to the disk. Chkdsk attempts to fix these problems past repairing soft bad sectors, and marker hard bad sectors then they won't be used once again.

That may all sound very technical, but don't worry: you don't need to understand the ins and outs of how it works to know when y'all should run it.

We recommend running chkdsk every few months as function of routine maintenance along with using a S.M.A.R.T. tool for drives that back up it. Yous should too consider running it whatsoever time Windows has shut downwardly abnormally—such as after a power loss or arrangement crash. Sometimes Windows will automatically run a scan during startup, but near often you'll take to practice it yourself. Even if you're just having foreign problems with apps not loading or crashing that you oasis't been able to resolve another way, you might consider checking the disk.

For instance: I one time had a problem where Outlook suddenly started crashing on me shortly after loading. Subsequently a lot of troubleshooting, a chkdsk scan revealed I had bad sectors where my Outlook data file was stored. Fortunately, chkdsk was able to recover the sectors in my instance, and everything went back to normal afterward.

If chkdsk does see problems—especially difficult bad sectors—that it can't repair, data tin go unusable. It's not very likely, but it tin happen. For that reason, yous should ever make certain you have a good backup routine in identify and back up your PC before running chkdsk.

The chkdsk tool works pretty much the same in all versions of Windows. We'll be working with Windows x in this article, then the screens may expect slightly dissimilar if you're using Windows 7 or 8, but chkdsk performs the same, and we'll indicate out where any procedures differ. We'll likewise talk about running it from the Command Prompt, in cases where y'all can't even boot into Windows.

How to Check a Disk from Windows

Running the Check Disk tool from the Windows desktop is easy. In File Explorer, right-click the drive y'all desire to cheque, and so choose "Properties."

In the properties window, switch to the "Tools" tab and then click the "Check" button. In Windows 7, the button is named "Check at present."

In Windows viii and ten, Windows may inform you that information technology hasn't institute any errors on the drive. You tin can still perform a manual scan by clicking "Scan drive." This will kickoff perform a scan without attempting any repairs, so it will non restart your PC at this point. If the quick deejay scan reveals any problems, Windows will present that selection to you. If you lot want to forcefulness information technology, though, y'all'll take to use the control prompt to run chkdsk—something we'll be covering a bit later in the article.

Later Windows scans your drive, if no errors were plant, you tin just click "Close."

In Windows 7, when you click the "Check at present" push button, you'll come across a dialog that lets yous choose a couple of extra options—namely whether y'all also want to automatically ready file arrangement errors and browse for bad sectors. If you want to perform the well-nigh thorough disk check, get alee and select both options and then click "Start." Just be enlightened that if you add a sector browse to the mix, checking the disk can take quite a while. Information technology may exist something yous want to do when you don't need your computer for a few hours.

If you elect to set file system errors or browse for bad sectors, Windows won't be able to perform a scan while the disk is in employ. If that happens, you'll have the option to cancel the scan or schedule a deejay check to happen the side by side time you restart Windows.

How to Check Up On or Cancel a Scheduled Disk Cheque

If you're not sure whether a disk cheque is scheduled for your next restart, it's easy plenty to check at the Command Prompt. You lot'll need to run Command Prompt with administrative privileges. Printing Start and then type "command prompt." Correct-click the issue and then choose "Run as administrator."

At the prompt, type the following command—substituting the bulldoze letter of the alphabet if necessary.

chkntfs c:

If you accept scheduled a manual check of the drive, y'all'll see a message to that upshot.

If Windows has scheduled an automatic check of the drive, you'll meet a message letting you know that the volume is dingy, which only means it'southward been flagged with potential errors. This serves as indication that Windows will run a check the side by side time it starts. If no automatic scan is scheduled, yous'll just see a message letting yous know that the volume is not dirty.

If a disk bank check is scheduled for the next time you kickoff Windows, only accept decided you don't want the bank check to happen, you can cancel the check by typing the post-obit control:

chkntfs /10 c:

You lot won't get whatsoever kind of feedback that the scan has been cancelled, but information technology will accept been. This command actually excludes the drive from the chkdsk command for the next start. If y'all do restart to find that a scan has been scheduled, Windows is also kind enough to provide you with about 10 seconds to skip the browse if you want to.

How to Apply the ChkDsk Control at the Command Prompt

If you're willing to apply the Command Prompt (or y'all have to because Windows won't boot properly), you can exert a little more control over the disk checking procedure. Plus, if you're using Windows 8 or ten, it'due south the only way to force automatic fixing or bad sector scanning into the mix. Open up the Control Prompt with administrative privileges past hitting Windows+X and selecting "Command Prompt (Admin)." You'll be using the chkdsk command. The command supports a number of optional switches, but nosotros're by and large concerned with two of them: /f and /r .

If yous simply use the chkdsk command by itself, it will scan your drive in read-just manner, reporting errors but non attempting to repair them. For this reason, it can usually run without having to restart your PC.

If you want chkdsk to attempt to repair logical file system errors during the browse, add the /f switch. Note that if the drive has files that are in apply (and it probably will), you'll be asked to schedule a scan for the side by side restart.

chkdsk /f c:

If you want chkdsk to scan for bad sectors as well, you'll use the /r switch. When y'all utilise the /r switch, the /f switch is implied, meaning that chkdsk will scan for both logical errors and bad sectors. But while it's non really necessary, it likewise won't hurt anything if you lot throw both the /r and /f switches on the control at the same fourth dimension.

chkdsk /r c:

Running chkdsk /r gives you the nearly thorough scan yous can perform on a volume, and if you lot have some time to spare for the sector check, nosotros highly recommend running information technology at least periodically.

There are, of form, other parameters you can employ with chkdsk . And then, for the sake of completeness—and your geeky enjoyment—here they are:

C:\>chkdsk /? Checks a disk and displays a status study.  CHKDSK [book[[path]filename]]] [/F] [/5] [/R] [/Ten] [/I] [/C] [/50[:size]] [/B]    book          Specifies the bulldoze letter of the alphabet (followed past a colon),                   mountain point, or volume name.   filename        FAT/FAT32 just: Specifies the files to check for fragmentation.   /F              Fixes errors on the disk.   /V              On Fat/FAT32: Displays the full path and proper noun of every file                   on the disk.                   On NTFS: Displays cleanup letters if any.   /R              Locates bad sectors and recovers readable information                   (implies /F).   /Fifty:size         NTFS only:  Changes the log file size to the specified number                   of kilobytes.  If size is not specified, displays current                   size.   /X              Forces the book to dismount starting time if necessary.                   All opened handles to the volume would and so be invalid                   (implies /F).   /I              NTFS simply: Performs a less vigorous check of index entries.   /C              NTFS only: Skips checking of cycles inside the folder                   structure.   /B              NTFS simply: Re-evaluates bad clusters on the volume                   (implies /R)  The /I or /C switch reduces the corporeality of time required to run Chkdsk by skipping certain checks of the book.

Hopefully, Chkdsk will gear up whatsoever hard bulldoze bug you may have, and you can get back to using your computer ordinarily.
