Windows has two inbuilt disk utility
command options named CHKDSK & SCANDISK. Any one
can be used to fix hard drive bad sectors, blocks, registry errors
and many other which is responsible for uncertain shutdown or system
restart in loop. First & foremost, you need to know why these two
options are so popular among Windows users and when they are used.
CHKDSK
Microsoft introduced this disk utility
command since before 2000 and can be found in all the latest versions
of Windows OS. CHKDSK command can be used to check the file system
integrity status, directories, bad sectors, blocks, & registry
errors as well as fix them. It is mostly helpful in the case when
system becomes unbootable or giving you a series of popup error
messages.
You can use it directly by going to
command prompt (Press CTRL + Run & Type CMD) or by going
to explorer, right click on any specific drive,go to properties
option and then select Tools tab, where a button is located named
‘Check Now’ (see in the image below).
Linux & MAC operating system uses
the same fsck command (stands for file system check) to check hard drive errors and fix it.
SCANDISK
SCANDISK is an improved GUI
based method unlike CHKDSK utility to manually check physical errors
on the hard drive as well as file system structureand repairs them
automatically. However, if you running system using NTFS file system
method, you cannot use this feature as it is restricted by Microsoft
to only for older versions of Windows like 2000, NT etc.
You can run SCANDISK graphically by
going to Start – Programs – Accessories – System Tools and
click on SCANDISK (See in the Image below)
Why Some of My Files was Lost after
Performing CHKDSK Operation?
Failed startup, virus corruption and
file system damages are the reasons after which the system needs to
run check disk utility. Either it will automatically initiate just
after starting the system (though you have 10 seconds on click cancel
on it) or you can run it yourself by using command prompt or by going
to drive properties > tools tab> Check Errors.
In both cases, check disk utility
usually checks your file system for errors and can mistakenly mark
either system files or any of your precious file that looks dangerous
for CHKDSK utility and then tries to repair them. In such cases,
CHKDSK utility removes the file addresses, delete the space it covers
and mark them as ready to store any new files. So if you believe that
some of your files were missing or deleted due to running check disk
utility, you need to stop using the drive and take help of any
professional recovery software.
Data recovery software is an
efficiently designed program to scan and recover the lost, hidden or
infected data from the hard drive and other removable media. All you
need is to download the professional recovery software from a reputed
company having expertise, experience and equipment’s in recovering data from such conditions.
