“I got a Western Digital My Passport 0830 2TB external HDD drive and it was working very well. I use it as my movie archive drive […] I connected the HDD to my PC usb, it took a long time but it couldn’t load it. It was in my computer window but you couldn’t open it […] HDD appears with no used space bar (both windows 7 and 8.1) and it has written 0 bytes of free space. While all my data takes just 811 GBs! and the only hidden files and folders inside are my own hidden files and folders. I see nothing else to fill the space. I used properties on all that files and folders. 811 GBs no doubt. “

What Does “Hard Drive Shows 0 Bytes” Mean?

When a hard drive shows 0 bytes, the OS cannot read its file system. The storage space appears empty or unallocated. However, this does not always mean your data is gone. It simply means the system cannot access it properly. This issue often occurs due to file system errors or corruption.

Common Causes of a Hard Drive Showing 0 Bytes

There are several factors that can lead to this problem. Understanding the cause helps you choose the right solution.

• Unexpected Shutdown: One of the common causes of this issue is an improper system shutdown. The system crashes due to an abrupt power disconnection. It prevents the OS reading the data.
• Malware Attack: A Malware or a computer virus can damage or hide your files. Some viruses modify the drive structure or partition details. This can make the drive appear empty.
• Bad Sectors on the Drive: Bad sectors are damaged areas on the disk surface. If critical sectors are affected, the drive may show 0 bytes. This is often seen in aging or physically damaged drives.
• Drive Shows as RAW: Sometimes the file system changes to RAW format. This means the system cannot recognize the file system type. As a result, the drive appears empty.
• Partition Table Damage: The partition table helps the system locate data on the drive. If it gets corrupted, the drive may not display stored data.

Note: For external HDD or SSD, removing the drive without following proper ejection process can be a cause of the problem.

Before trying Windows troubleshooting, confirm whether your system detects the drive.

• Open Disk Management on your system.
