“When I opened my PC today the hard disk drive is showing 0 bytes free and 0 byte occupied at the same time. I am confused, what needs to be done now? How do I resolve the issue and bring back my PC in normal condition.”

The hard disk drive is an electromechanical data storage device which is prone to corruption and damage. When you come across a situation when the hard disk is showing 0 bytes of free space, you wouldn’t be able to access the data. Such a condition though alarming, aren’t uncommon. That is the reason one should always keep multiple copies of the important data preferably at different locations and on different storage devices. However, in most of the scenarios data is not backed up. Hence, it is necessary to be aware of the techniques of hard drive recovery.

Let’s first be aware of the reasons why a hard drive isn’t detected on a computer. This, in turn, plays a vital role in rectifying the problem.

Factors leading to Hard Drive Showing 0 Error

Some of the common factors responsible for error are listed below:

  • Removing hard drive without Ejection
  • A power surge
  • Hard drive usage in an improper way
  • Virus attack or malware infection
  • Interruption during partitioning or formatting of the hard drive
  • Corrupt files in the system and bad sectors

When you encounter such a situation, check the hard drive by connecting it to another PC. If the hard drive still shows 0 bytes and the RAW file system, implement the solutions stated below.

  1. Rename the Hard Drive Letter

Steps are listed below to rename the hard drive letter:

  • Press ‘Windows+R’ then type diskmgmt.msc and hit ‘Enter’. You will be directed to the Disk Management window.
  • Right-click on the hard drive that shows 0 bytes free space and choose ‘Change Drive Letter and Paths’.
  • Then click on the ‘Change’ button and choose a drive letter from the drop-down list.
  • Click ‘OK’ and then click ‘Yes’ when prompted. Click ‘OK’ to confirm and close the box.

You would be able to access the drive and stored files on the drive once you restart the system.  

  1. Run the CHKDSK Utility

If the file is corrupted due development of bad sectors in the drive, CHKDSK helps in repairing the file system. To fix the hard drive showing 0 bytes issue, execute CHKDSK utility on the hard drive, as per the steps mentioned below.

  • Press ‘Windows+S’ and type cmd.
  • Then right-click on Command Prompt and select ‘Run as administrator’. The Command Prompt window appears.
  • Type chkdsk X: /r /f where X is the hard drive letter that shows 0 bytes; /r & /f are the chkdsk parameters. Hit ‘Enter’ to execute chkdsk.

Hold on until the process is complete. This could most likely fix the hard drive error. Try to access the files after restarting your PC.

  1. Use Microsoft Safety Scanner

Microsoft Safety Scanner safeguards your system from spyware, viruses, and other malicious software and applications installed on the PC that might be causing the issue. You can download the security scanner tool from Microsoft for free that is compatible with your existing antivirus software. But, you will have to be extra careful while using the tool as it repairs the bad sector if found any while scanning. This may eventually lead to data loss.
