What Is Chkdsk?
Chkdsk or checkdisk is a utility tool provided by Microsoft Corporation for error checking the volume partition. It automatically repairs error on the volume partition if any and can be of great help if you hard disk have encountered Bad sectors or some portion of your hard drive have become unreadable.
Windows 7 Chkdsk
Chkdsk is a very useful tool provided for NTFS volumes and is bundled with windows 7 to check and repair errors. It can also check errors for FAT and FAT32 volumes. You can run Chkdsk from three ways.
Chkdsk Command Prompt
Click Start –> Run –> Type “cmd” (without quotes) –> press Enter –> Type “Chkdsk X:” (where X is the name of the drive you want to check) –> Press Enter
Remember this command can be executed only with Admin privileges. So if you are not running Command prompt as an Admin use this alternative method to execute checkdisk.
Open My Computer –> Open “C” drive –> Open folder “Windows”–> Open folder “System32” –> Type “cmd” in the search box in the upper right hand side of the explorer bar –> select the one with black icon –> Right click it and select “Run As Administrator” –> Select “Yes” –> Type “Chkdsk X:” and Press Enter.
Chkdsk Graphical User Interface
Open “My Computer” –> Right click the drive you want to check for errors and select properties à select the tab “Tools” –> Select “Check Now” button –> Select “Yes”
Now the System will open a window with two options. Select your choice (I would suggest select both the options) and then click “START”.
Chkdsk Recovery Console Check
Now this is the Best Option for checking any serious errors of the partition volume. If the above two options fail to provide remedy to your problem, this option could be the only solution. Before you start with the recovery procedure I would suggest you to be very cautious and take a back up of the data inside your drive to some other drives if possible.
–>Restart Your System
–>Start Pressing “F8” before the splash screen appears (This will take you inside the advanced boot menu options)
–>From there Select “Safe Mode with Command Prompt” (Now windows will load all essential files required for its startup and will load with a window showing the Command Prompt Panel)
–>Now enter this command without the quotes “Chkdsk /r” [Remember there is a space between Chkdsk and /r]
Difference Between Chkdsk Win 7 & Scandsk in Windows 7
Though both these command are taken for granted to be doing the same task, there is a level of difference between them. The most important is that the Logical system file errors can be fixed by Chkdsk but scandsk is unable to fix such problem. Moreover Chkdsk is somewhat a better tool and an upgraded version for carrying out repair and recovery tasks for NTFS file systems.
This is the reason why we do not have scandsk in windows 7. The NTFS volume partitions are something which scandsk is not compatible with. Hence Microsoft replaced all its tasks to chdsk program. Win 7 chkdsk program can easily repair logical errors do some tasks which scandsk was unable to do and most importantly it’s the next gen repair tool for Windows Platform.
