0 bytes driveAfter turning on your computer, you find that your hard drive is reading 0 bytes. This problem can also occur for flash drives and files or folders. When trying to open something with 0 bytes, Windows won’t let you, and instead, will display an error message saying it cannot be opened.

Worry not, as this problem has been encountered and fixed many times before. If your hard drive shows 0 bytes, read this article in full to figure out why this occurs and how you can fix it.

What Does 0 Bytes Mean?

Bytes are a unit of measurement that tells you how large any given file is or how much space has been taken up on a drive. When something reads 0 bytes, it means there is no data there. For a file, this means the file is empty. For a drive, this means the drive is empty.

However, just because it says 0 bytes doesn’t mean the file, folder, or disk is actually empty. It could be an incorrect reading due to a problem with the drive. For instance, if a folder is showing 0 bytes even when you know there is data inside, it means there’s an issue somewhere.

Common Reasons Why a Hard Drive Displays 0 Bytes

There are numerous reasons why a hard drive will display 0 bytes. Here are the most common ones:

Reason Description
🦠 Malware In this case, a 0 byte virus could have infected your computer, leading your files, folders and/or disk to read 0 bytes. This can typically be resolved by scanning your computer with an antivirus program.
💾 Corrupted file system When a file system becomes corrupted, it can prevent your computer from booting and cause your partition to read as 0 bytes.
🔌 Improper shutdown If your computer is shut down before it can finish performing an important action, this could lead to corruption of both your data and file system.
❌ Bad sectors A few bad sectors is normal for a hard drive, but a sudden increase in bad sectors could point towards an underlying issue with your hard drive that’s causing the 0 bytes problem.
🚫 No space Of course, your disk can read as 0 bytes remaining because there is not enough storage space to store any additional data. In which case, simply deleting unneeded data or upgrading your storage will suffice.

How to Recover Data From a Drive That Shows 0 Bytes

Before you fix the hard drive that shows 0 bytes, you should first recover any data currently on it if the drive is appearing in Disk Management with the correct size. This keeps it safe in the event that one of the fixes goes wrong and your hard drive is wiped. To do this, we’re going to use Disk Drill, as it allows you to create a byte-to-byte backup of the drive to recover from.

These steps will guide you through how to recover data from a drive that shows 0 bytes with Disk Drill:

  1. Download and install Disk Drill. Make sure you don’t install it to the same drive facing the 0 bytes problem.
  2. Click Drive Backup.select drive backup
  3. Select the drive and click Byte-to-byte Backup.click Byte-to-byte Backup
  4. Give the backup a name and specify an output location on a separate physical partition. Click OK. Click Done when it’s finished.name backup and start creating
  5. Go back to the Storage devices section, then click Attach disk image. Attach the image you just created.attach disk image
  6. Select the backup image, then click Search for lost data.scan backup image
  7. Click Review found items when the scan finishes.review found items on disk
  8. Select the files you want to recover and click Recover. Make note of the Recovery chances column to see your chances of recovering each file.select the files and recover
  9. Select an output location that’s not on the same problem disk. Click Next.select destination and recover files

How to Fix the 0 Bytes Issue

Now that your data is safe, let’s take a look at various ways you can fix the 0 bytes issue.

Method 1:Try Another Port or Computer

First things first, you should isolate where the issue resides. It’s definitely possible for this problem to be caused by the hardware of your computer, such as a faulty hard drive power connector.

To ensure the problem is localized to your hard drive, consider removing the hard drive and connecting it to another machine for testing. If the problem persists, then you can comfortably say the problem is with the hard drive.

Method 2:Repair Drive with CheckDisk

If one of your folders says Size on disk: 0 bytes, it could be related to your file system. CheckDisk is a Windows repair tool that can scan your drive for file system-related errors and resolve them. Even if it can’t repair your particular issue, it may be able to give you more information about what’s causing it.

Follow these steps to repair a drive using CheckDisk:

  1. Right-click Start and select Windows PowerShell (Admin).Opening an elevated PowerShell console.
  2. Type chkdsk F: /f /r. Replace F: with your own drive letter. Press Enter.Running the CheckDisk command.

Method 3:Repair with TestDisk

If your partition says 0 bytes, confirm that diskpart shows 0 too. If it does, it could be that the partition has become corrupted. Thankfully, using TestDisk, we can recover the entire partition to how it once was.

These steps will guide you through using TestDisk to recover a lost or corrupted partition:

  1. Download and unzip the contents of the TestDisk file. Open testdisk_win.
  2. Press Enter on the Create option.Creating a log of the actions to follow.
  3. Highlight the disk you want to recover the partition of, then press Enter to proceed.Selecting which disk to scan.
  4. Select your partition table type. TestDisk often detects this automatically.Choosing the partition table type.
  5. Press Enter on the Analyse option.Analyzing the current disk.
  6. Press Enter again to begin the quick search.Starting the quick search for lost partitions.
  7. Press Enter on the discovered partition.Reviewing the discovered partition.
  8. Move to the Write option, then press Enter.Writing the found partition.
  9. Press Y to confirm.

Method 4:Repair Damaged MBR

A damaged MBR (Master Boot Record) may be the reason why your hard drive space isn’t displaying correctly. Repairing it will ensure the boot record has all the correct information pertaining to your drive.

To repair a damaged MBR, you will need either a Windows installation DVD or a bootable recovery USB. Follow these steps to repair a damaged MBR:

  1. Boot into the Windows installation environment.
  2. Click Repair your computer.Choosing the 'Repair your computer' option.
  3. Click Troubleshoot.Troubleshooting this PC.
  4. Click Command Prompt.Accessing the recovery command prompt window.
  5. Type bootrec /FixMbr and press Enter.Running the bootrec fixmbr command.

  7. Type bootrec /ScanOs and press Enter.Running the bootrec scanos command.
  8. Type bootrec /RebuildBcd and press Enter.Running the bootrec rebuildbcd command.
  9. Restart your computer normally and check to see if the disk still reads 0 bytes.

Method 5:Resolve with Format

Formatting your drive is akin to performing a factory reset. It’s a common method for fixing failed hard drives. Formatting the drive will delete all data presently on it, but it also resolves any issues relating to the file system that’s currently on it.

The below instructions will guide you through formatting your drive:

  1. Right-click Start and select Disk Management.Opening Windows Disk Management.
