Resetting a hard disk drive (HDD) refers to erasing all of the data on the drive and restoring it to a factory default state. This can be done for several reasons, such as before selling or disposing of the HDD, troubleshooting performance issues, or wiping sensitive data before donating a computer.
Why Would You Want to Reset a Hard Drive?
There are a few common reasons why someone might want to reset their HDD:
- Preparing to sell or give away a computer – Resetting the HDD erases all personal data and leaves it in a fresh state for the next owner.
- Troubleshooting performance issues – If the HDD is having errors or running slowly, resetting it may help resolve these problems.
- Before donating a computer – Charities and schools often prefer donated computers to have the HDD reset to protect the privacy of the previous owner.
- Removing sensitive data – Those working with highly confidential data may need to reset HDDs before disposing of old computers to ensure no data is recoverable.
- Removing viruses and malware – Resetting can wipe malicious programs and files from the HDD.
- Starting fresh with a new operating system – Resetting the drive provides a blank slate for a fresh OS installation.
Are There Risks to Resetting a Hard Drive?
Resetting a hard drive does carry some risks:
- All data will be erased – Resetting removes all files, documents, programs, music, photos and other personal data. Be sure to back up anything you need before starting.
- Potential hardware damage – Repeatedly resetting HDDs can reduce their lifespan by wearing them out physically. Reset only when truly necessary.
- Accidental loss of partitions – Mistakenly resetting the wrong HDD could result in deleting vital partitions and data.
- Time consuming process – Resetting can take several hours depending on the drive size and method used.
- OS reinstallation required – The PC will need the operating system and programs reinstalled after resetting the HDD.
How to Reset a Hard Drive
There are a few different ways to reset a hard disk drive depending on your needs:
Method 1: Using DiskPart on Windows
DiskPart is a command line utility built into Windows that allows resetting drives. Here are the steps:
- Backup any data you need from the HDD.
- Open the Command Prompt as administrator.
- Type “diskpart” and press enter.
- Type “list disk” to identify the disk number of the HDD you want to reset.
- Type “select disk X” where X is the number of the target disk.
- Type “clean” to erase all data on the selected disk.
- Exit DiskPart and close Command Prompt when finished.
Method 2: Using Disk Management on Windows
Disk management provides a graphical interface for resetting drives on Windows:
- Backup data from the HDD first.
- Right click the Start menu and select “Disk Management”.
- Right click the disk you want to reset and choose “Delete Volume”.
- Select the newly unallocated space, choose “New Simple Volume”.
- Follow the wizard to initialize and format the empty drive.
Method 3: Using Drive Erase on Mac
Drive Erase is included on Macs for erasing HDDs:
- Backup data before erasing.
- Open Disk Utility.
- Select the HDD you want to erase.
- Click Erase and choose a format like Mac OS Extended.
- Enter a name for the reset drive and click Erase.
Method 4: Using Third Party Tools
There are many free and paid third party drive erasing tools available:
- DBAN (Darik’s Boot and Nuke) – Free open source tool for completely deleting data.
- Active@ KillDisk – Securely overwrites data multiple times.
- Hard Disk Eraser – Wipes drives on Windows and makes data unrecoverable.
- Mac Disk Eraser – Donates profits to human rights and erases HDDs on Macs.
- WipeDrive – Commercial solution meeting various data erasure standards.
Method 5: Using Manufacturer Tools
Most HDD manufacturers like Seagate, Western Digital and Toshiba provide free tools for erasing their brand of drives. These tools integrate directly with the HDD firmware and tend to be thorough and reliable. Refer to the manufacturer’s website for their particular data erasure tool.

Frequently Asked Questions
Is a quick format the same as fully resetting a hard drive?
No, a quick format does not actually erase data from the drive. It simply clears the index listing the files, making data inaccessible but potentially recoverable with the right tools. To fully reset a drive all data must actually be overwritten or physically destroyed.
Can deleted files be recovered after resetting a hard drive?
No, properly resetting a HDD using a full format, overwrite, or secure erase makes deleted files unrecoverable. Recovering data requires reading portions of intact files. Resetting eliminates file contents.
Is a physical destroy the most secure HDD reset method?
Physically destroying the HDD platters and mechanism, for example by degaussing or shredding, is the most secure reset option. However it also permanently destroys the drive. Most reset options focus on erasing data while keeping the hardware reusable.
How long does it take to reset a hard drive?
The time to reset a HDD depends on the drive capacity and reset method. Quick formats can take minutes while thorough overwriting can take hours for large multi-terabyte hard drives. Solid state drives reset faster than physical platter drives.
What tools are needed to reset a hard drive?
On Windows PCs the built-in DiskPart and Disk Management utilities allow resetting drives. On Macs the included Drive Erase tool can reset HDDs. Third party erasing tools are available for enhanced features. Some methods just require basic computer access.
Can an external USB drive be reset the same way as an internal HDD?
Yes, external USB hard disk drives use the same technology as internal drives and can be reset in the same ways by hooking up the external drive and using drive erasing software or commands. This allows resetting portable external drives easily.
Is resetting an SSD hard drive different than a HDD?
SSDs or solid state drives differ from mechanical hard disk drives in some ways but can still be reset using the same techniques. Because SSDs lack magnetic platters, options like degaussing do not apply to them. But reformatting or using drive erasing tools works for both HDDs and SSDs.
How can you tell if a hard drive was ever reset?
There are a few ways to potentially tell if a HDD has been erased and reset in the past:
- Very low number of hours powered on for the drive’s age
- No files older than the reset date present
- Possibly inconsistent performance due to excessive resetting wear
- The model, size and firmware not matching expected for that system
However these are not foolproof ways to know if a reset occurred. The only guaranteed way is if you directly did and recall the reset yourself.
Is there any way to recover data from a reset hard drive?
If the drive was properly erased using a full format, overwrite, or secure erase method, there is no way to recover the old data. These methods actively destroy file contents making recovery impossible. If a quick format was used, recovery software could potentially restore deleted files.
How many times can a hard disk drive be reset before wear makes it unusable?
There is no specific count of resets after which a HDD will fail, but repeatedly initializing, formatting, and overwriting cells does progressively wear them out physically and technically shorten lifespan. In general HDDs can handle tens to hundreds of resets before mechanical breakdown depending on the model.
