Chkdsk is the command that checks the status of hard disks (volumes) and floppy disks and fixes the logical file system errors, if occurred. This command is used on DOS and Microsoft Windows operating systems. The result of chkdsk may not necessarily be in read-only mode.
Ways to perform Check Disk
There are two ways to perform disk check:
Restart the computer to start the disk check.
Caution on files, which are open
Never run chkdsk /f when files are open because it may cause loss of data. Chkdsk command cannot be run to check a disk on a network drive.
There are two types of errors in the file system, which needs special care. One is logical and another is physical disk errors. Logical errors in file system are identified by chkdsk command. When the system prompts for chkdsk during boot up, then it is recommended to perform chkdsk, always (This would happen because of power failure or improper shut down of the system).
Bad sectors are marked as “bad” when the chkdsk reports them. Chkdsk does not fix cross-linked files. Maually a cross-linked file can be fixed by copying the files or directories somewhere else and deleting the original files or directories.
Redirecting the output of CHKDSK to a file
chkdsk a: > filename
filename is the name of the file to which the output of the chkdsk is redirected. In this scenario, the chkdsk command does not fix the errors. It simply redirects the result to the specified file. To fix the errors, following command should be used.
Recover data from bad hard drive
Bad hard drive refers to hard drive containing bad sectors, which effects the data stored in it. There are many reasons which leads to bad hard drive like OS crash, virus attack, file system corruption etc. In order to overcome such scenario, Remo Recover makes use of advanced scan algorithm to restore back all lost files stored on the hard drive.
