How to cancel a currently ongoing format

"Hello, I have an issue with my WD Elements external hard drive. I'm trying to format it using Diskpart on Windows. However, after entering the command [format fs=ntfs], the process has been stuck for two hours and is only 12% complete! Can I interrupt the formatting and start over? It seems that Windows can't safely unformat it. Please help!"

When encountering some common hard drive issues, such as hard drive very slow suddenly, unable to open the hard drive normally, or bad sectors on the hard drive, people usually think formatting the hard drive is a good option. Microsoft Windows provides several ways to format internal hard drives and some external USB flash drives in File Explorer, Disk Management, and Command Prompt.

The time it takes to format a storage drive depends on how much is stored on it, usually ranging from a few seconds to hours. However, sometimes, people get stuck in the formatting process for an extended period, like more than 24 hours, and they need to stop the formatting urgently. When the hard drive formatting takes too long, two concerns may arise. Will stopping the formatting halfway damage the hard drive? What if Windows fails to cancel the formatting even after closing the formatting window?

Method 3: Format through File Explorer

How to Recover Data from a Formatted Hard Drive

The risk involved here is that once the formatting begins, interrupting it carries a risk. If you stop the process in the middle, especially after it has been going on for some time, you end up with an inaccessible hard drive that appears as RAW drive.

For those who forget to back up the hard drive before formatting and then cancel the formatting, you can download and use Data Recovery Wizard to recover data from a partially formatted hard drive. Let this professional Data Recovery Wizard tool help you retrieve all the deleted data from the uncompleted formatted hard drive.

Note: To ensure a higher chance of data recovery, do not install the data recovery tool on the formatted disk.

Select a drive and click “Scan”.

Step 2: The software will start scanning all the lost data and files. After the scan, you can click "Filter" to filter specific file types to quickly find the needed files. Or you can click "Search File or Folder" to select the data you want to recover.
