  • /r- Finds any corrupt sectors on the disk and restores readable data.
  • /x- Unmounts the drive before the procedure begins.
  • /b- Removes any bad clusters from a disk and rechecks all allocated and free clusters for errors. Use it with NTFS File System.

Bonus Tip: The Reasons and Symptoms of Corrupted Hard Drive

Why does the hard disk crash or become corrupted? Here are a few major causes.

  • Logical damage: Virus infection, faulty sectors, an unknown file system, an unformatted disk, a raw file system, and a lost or damaged partition table.
  • Physical damage: Short circuits, chip damage, corrupted headers, being dropped from great heights, and the aging of the hard disk's moving parts.
  • Manual damage: Improper human actions like an unexpected power outage, removal without safe removal, improper system shutdown, etc.

Corrupted hard drives typically indicate that they are not being recognized or functioning correctly. The signs of a failing or corrupted hard drive can vary from case to case, but if you see one or more of the symptoms described below, you should handle your hard drive cautiously.

  • The majority of your hard drive's files are corrupted or missing.
  • You get an error notice when you connect the hard drive to the computer or attempt to open it. For instance:

"X:\ is not accessible. Access is denied."

"You need to format the disk in the drive before using it. Do you want to format it?"

  • When checking in Disk Properties, the hard disk shows 0 bytes of free and utilized space.
  • In Disk Management, the hard disk is shown as RAW.

Even though your hard drive is corrupted, you do not have to throw it away just yet.
