Quick Answer

Yes, it is possible to fully wipe and erase a drive in Windows 10. The easiest way is to use the built-in Diskpart tool from the command line. Diskpart’s ‘clean’ command will overwrite all data on the selected drive with zeros, effectively wiping it. Another option is to use third-party disk wiping software that utilizes multiple pass overwrites for deeper cleaning.

Ways to Wipe a Drive in Windows 10

There are a few different ways to securely erase data from a hard drive in Windows 10:

Using Diskpart from Command Prompt

Diskpart is a command line utility built into Windows that allows you to completely clean and reformat a drive. To use it:

Open the Command Prompt as administrator
Type ‘diskpart’ and press enter
Type ‘list disk’ to show available disks

Select the disk you want to clean by typing ‘select disk X’ (where X is the disk number)
Type ‘clean’ and press enter to start wiping the drive

The clean command overwrites all sectors with zeros, effectively erasing any previous data.

Using Disk Management

Disk Management is another built-in Windows tool that can be used to wipe a drive:

Open Disk Management (right-click start menu and select Disk Management)
Right-click on the disk you want to wipe and select ‘Format’

Make sure ‘Quick Format’ is unchecked
Select file system (NTFS is recommended) and start the formatting process

This performs a full format, overwriting all existing data with zeros.

Using Third-Party Disk Wiping Software

For more secure drive erasure, specialized disk wiping tools are recommended. Some popular options:

DBAN (Darik’s Boot and Nuke) – boots from a CD/USB and completely destroys data
Eraser – securely overwrites data multiple times

KillDisk – wipes drives mechanically with multiple algorithms
Active@ KillDisk – offers DoD 5220.22-M compliant wiping methods

These employ multiple overwriting passes, advanced algorithms, and meet wiping standards to make data recovery impossible.

How Does Disk Wiping Work?

Disk wiping works by overwriting the existing data on a hard drive. This is necessary to securely erase data as simply deleting files or formatting does not actually remove the underlying data – it just removes pointers to it and marks the space as available for new data.

To prevent recovery, the drive needs to be overwritten with new meaningless data. Here’s a bit more detail:

Simple Overwrite

A single pass overwrite writes zeros or random data across the entire drive. This makes previous data essentially unrecoverable.

Multi-Pass Overwrites

For highly sensitive data, multiple pass overwrites are more secure. The drive is wiped multiple times with alternating data patterns. This prevents any chance of leftover data traces.

Advanced Algorithms

Some software uses military-grade wiping algorithms like DoD 5220.22-M (7 pass) and Gutmann method (35 pass). These repeatedly overwrite with complex patterns for the highest security.

Why Should You Wipe a Drive?

There are a few good reasons to completely wipe a hard drive:

Reselling or Donating a Drive

If you plan on selling, giving away or donating an old drive, you want to make sure all personal and sensitive data is removed first.

Removing Sensitive Data

Before disposing of old business or government drives, proper disk wiping is required to delete confidential data, financial reports, classified information, etc.

Repurposing or Reassigning a Drive

When moving an old drive to a new machine or user, you’ll want to wipe it to provide them with a clean slate.

Troubleshooting Performance Issues

Wiping and reformatting a drive to factory-fresh state can help resolve any filesystem errors or performance issues.

Considerations Before Wiping a Drive

There are a few important factors to keep in mind before wiping a drive:

Backup Important Data First – Ensure you have backups of anything important before wiping a drive!

Wiping is Permanent – Wiped data cannot be recovered by consumer software once it’s overwritten.
Entire Drive Will Be Erased – The wipe process erases the entire drive, not just selected data.
System Drive Wiping Requires Boot Media – To wipe the current system drive, you’ll need bootable media like a CD or USB key.

So if you need to retain anything on the drive, make sure to copy it elsewhere first!

Step-by-Step Guide to Wipe a Drive with Diskpart

Here is a step-by-step walkthrough for securely wiping a drive with Diskpart from the command prompt:

Open Command Prompt as Administrator – Open the start menu, search for “Command Prompt”, right-click it, and select run as administrator. This opens Command Prompt with admin rights needed to wipe drives.

Type diskpart and Press Enter – This will start the Diskpart utility.
List Available Disks – Type “list disk” and press enter to display all disks detected by the system.
Select the Target Disk – Identify the disk number you want to wipe and type “select disk X” where X is the number. Ex: “select disk 2”

Verify Disk Selection – Type “detail disk” to view details on the selected disk and confirm it is the correct one.
Clean the Disk – Type “clean” and press enter to wipe the drive by overwriting data with zeros.
Exit Diskpart – When finished, type “exit” to close Diskpart.

Close Command Prompt – Type “exit” again to close the Command Prompt window.

The target drive is now wiped completely clean of previous data and ready for a new filesystem and usage!

Using Third-Party Wiping Software

For enhanced drive wiping security beyond Diskpart, third-party disk erasure tools are recommended. Here is an overview of using a popular data wiping utility called Eraser:

Download and Install Eraser – Get the latest version from https://eraser.heidi.ie and run the installer.
Select a Drive – Open Eraser, click Add Data Source, and choose the drive letter of the disk you want to wipe.
Choose Wiping Method – Under Erasure Method, select an algorithm like DoD 5220.22-M for a 7-pass overwrite.

Schedule or Run Wipe – Choose to perform the wipe immediately or schedule it for later.
Track Wiping Progress – View the status of the current wipe task and number of passes completed.
Verify Wipe on Reboot – After restarting, the drive should now appear blank and empty.

Following these steps will securely wipe the selected drive using advanced algorithms for permanent, irrecoverable data deletion.

How to Wipe a Drive Before Selling a Computer

When preparing a computer for sale or disposal, you’ll want to completely wipe personal information from the hard drive. Here are the steps:

Backup any data you need to keep onto external storage or the cloud.

Use Diskpart clean or third-party software to perform a full drive wipe.
If wiping the current system drive, use bootable media so the OS is not running from the drive.
Delete all existing partitions when prompted and recreate a fresh partition after wiping completes.

Format the blank drive with a new NTFS filesystem.
Reinstall Windows or the operating system from scratch after wiping.
The drive is now scrubbed and ready for the new owner with no recoverable user data left.

Wiping user data protects your privacy when passing a computer on to someone else. Securely erasing drives should be standard practice when decommissioning old computers.

How to Wipe an External USB Drive

To wipe an external USB flash drive or hard drive, follow these steps:

Connect the USB drive to your computer.

Open Disk Management and locate the USB drive.
Right-click and choose Format. Make sure Quick Format is unchecked.
Under File System choose NTFS and start the formatting.

Alternatively, use diskpart or third-party software for a more secure wipe.
USB drives should be wiped before selling, donation or disposal.

The steps are largely the same as wiping an internal drive. Just pay close attention to choose the correct USB drive letter or disk number before wiping to avoid accidentally erasing internal drives.

What Kinds of Data Can Be Recovered After Wiping?

Once a drive has been completely wiped using disk wiping software or tools like Diskpart, virtually no data can be recovered by conventional means. However, there are some exceptions:

Data remnants in system areas like drive slack space or gaps between partitions may persist in small amounts until overwritten.
Advanced forensic techniques using electron microscopes can read minute magnetic traces left on platters. This is expensive, difficult, and limited.

Some SSD drives retain copies of data after wiping due to wear-leveling algorithms. SSD wiping tools help mitigate this.
If the wiping process is interrupted, some deleted data may still be retrievable before it is fully overwritten.

For the average user though, a properly wiped hard drive is essentially impossible to recover meaningful data from. The best bet is to physically destroy drives containing highly sensitive information after wiping.

Can You Recover Files After Formatting a Hard Drive?

Formatting a hard drive does not securely erase data – it only removes file system information and marks space as available for reuse. Until the formatted drive is written over with new data, recovery is often possible:

Files remain intact in their original locations, marked as free space rather than deleted.
Unformatting utilities can reconstruct tables to make previously formatted partitions accessible again.

Data recovery software can scan disk platters and extract documents, photos, and other files after formatting.
Formatting limits recovery success and timeframe but does not prevent it. Wiping is required for secure deletion.

So if you have accidentally formatted an important drive, act quickly! Power down the drive immediately and use data recovery software to extract what you can before new data overwrites it.

Can You Recover Files After Wiping a Hard Drive?

With the right wiping techniques, recovering files from a wiped hard drive is essentially impossible:

Simple file recovery relies on filesystem metadata, which is destroyed during proper wiping.
Data remnants in slack space and gaps are overwritten multiple times by wiping algorithms.

Magnetic force microscopy can only recover minute traces, not usable data.
Each overwrite pass exponentially reduces the odds of meaningful content being retrievable.

Barring very expensive forensic methods and laboratory conditions, data recovery from a wiped drive has near-zero odds of success. The only sure way is to physically destroy drives.

Can Formatted Data Be Recovered from an SSD?

SSDs provide unique data recovery challenges after formatting due to wear-leveling algorithms:

Deleted files may persist until garbage collection erases original NAND flash blocks.
Wear-leveling rotates data around, producing remnant copies.

TRIM commands can discard deleted data from SSD logic but actual contents may remain.
Over-provisioning reserves extra NAND capacity, preserving data past deletion.

Still, data recovery from formatted SSDs is possible for a short window if they are immediately powered off and scanned by recovery tools before extensive rewrites occur.

Is a Quick Format Enough When Selling a Computer?

A quick format is not enough to securely wipe a hard drive before selling or disposing of a computer. Here’s why:

A quick format only deletes file system metadata, not the actual contents.
It marks all data as free space but does not actually overwrite it.

All original data continues to reside on the drive virtually intact.
Recovery tools can easily restore user files like documents and photos after quick format.

A full format overwrites all sectors, but even that is not enough. For proper sanitization before selling a PC, the drive needs to be completely wiped using disk wiping software or tools like Diskpart clean. This overwrites all data to ensure the next owner cannot recover any sensitive information.

Conclusion

Wiping a hard drive to permanently destroy data is critical when repurposing or disposing of old computers. By leveraging built-in tools like Diskpart and third-party software, drives can be completely erased to safeguard confidential information from recovery. Just remember: quick formats and deletions are not enough! Wiping must use multiple overwrite passes and advanced algorithms like DoD 5220.22-M to guarantee no remnants exist. With proper precautions, you can ensure data is rendered unrecoverable when the time comes to wipe your old drives.
