How to Wipe External Hard Drive in Windows 10

Wiping or erasing a hard drive is an effective way to permanently delete data without recovery. Although Windows doesn't offer a tool that can scan and wipe your external hard drive, there are still some methods you can choose to make it.

Method 1. Wipe External Hard Drive with a Windows 10 Data Wiping Tool

The first solution we recommend you try is to use EaseUS Windows 10 disk management tool, as this is the easiest way to wipe a hard drive, SSD, or external drive.  

EaseUS Partition Master, a superior disk partitioning program, provides a "Wipe data" feature to erase all disk data permanently in Windows 10/8/7. It can help you completely erase all of the data and partitions on your hard disk with solutions that meet DoD 5220.22-M Wiping Standard. Usually, after two erases, your data will be permanently removed and cannot be recovered anymore.

More Relevant Topics About Wiping External Hard Drive

If you also have any of the following frequently asked questions about hard drive erase, find solutions here.

1. How do you delete everything off your hard drive?

Wipe the drive to delete everything completely.

The only way to remove data off your HDD, SSD, external hard drive, SD card, or USB flash drive is by erasing the device.

Deleting files or formatting disks will not completely clear the files, they will still be on your hard drive and can be retrieved by professional data recovery software.

2. Can a wiped hard drive be recovered?

No, the erased hard disk cannot be recovered.

To permanently deleted previously stored data, the data wipe tool overwrites hard disk drive storage areas with the same data everywhere—often using a pattern of all zeros. Once the wipe operation is carried out, the files will not be recovered by any data recovery software. If the number of times to wipe the hard disk is set to 10, the data will never be recovered by any data recovery solution.

3. Format data VS wipe data

Formatting can be classified into low-level formatting (it is physical formatting and usually operated by manufacturer) and high-level formatting that can be carried out on the computer by users. High-level formatting only clears the FAT table (file allocation table), which makes the system think that there are no files on the disk, and does not erase the hard disk. After quick formatting, the hard disk data can be restored by data recovery tools.

Hard disk data wiping aims to completely delete the data on the hard disk through the related hard disk data erasing technology and standard (e.g. DoD 5220.22-M Wipe). After the hard disk is executed with full write and zero erasing, there is currently no professional data recovery company in the world capable of recovering the data, effectively ensuring the security and privacy of data.
