Method 1:
Use check disk command for any errors on hard disk -
Warning: Microsoft does not recommend interrupting the CHKDSK process. Microsoft does not guarantee the integrity of the disk if the CHKDSK program is interrupted .For safety you can back up your data before using the check disk command.
Use the check disk commands as follows:
- Press Windows Key + X, then choose Command prompt (Admin) from the context menu.
- In search window type 'cmd' and ENTER. Right click and select 'Run as administrator'.
- Type at the command prompt CHKDSK /P and press ENTER to scan the disk.
- Then type CHKDSK C: /F /R and press ENTER to repair corrupt sectors, if there are any.
NOTE: The root drive has to be C: and the command may schedule a task at the system startup, if it does, then press Y to schedule a task and restart the computer to perform chkdsk.
Once chkdsk completes, boot to the desktop and then check.
Important: While performing chkdsk on the hard drive if any bad sectors are found on the hard drive when chkdsk tries to repair that sector if any data available on that might be lost
