When you get rid of an old computer or upgrade your hard drive or SSD to something bigger, faster, or newer, you need to make sure your data is deleted from your old hardware. Why? If this is not the case, someone else could easily reach the hard drive and look at all your personal files and folders.

Wipe a drive under Windows
Step 1: Download Eraser
There are a number of applications that can erase your hard drive or SSD well but eraser is our favourite. It's free, intuitive and comprehensive. Since it must be run under Windows, you can not delete the drive on which you are running it. If you do not have an alternative drive to boot, consider an alternative tool like DBAN.
Download Eraser from the official website and install it like any other application.
Step 2: Create Task
Open the Eraser application and right-click (or tap and hold) in the main window in the Delete window and select New task . In the window that appears, make sure Manually Run is selected, and then select the Add Data button at the bottom of the window. Change the destination type to the drive of your choice.
Step 3: Select a deletion method
There are different extinguishing methods from which you can choose with their special advantages. For simplicity, a P seudorandom Data (1 Pass) is sufficient for basic personal information and SSDs. However, if you wipe a hard disk or are worried that certain data will be restored from your hard drive, a larger number of runs will have less chance of recovering that data. So select one with more passes to get more peace of mind if you want
Step 4: Perform the
Although you can set tasks to run automatically or at a scheduled time, we have set them up manually to give us a chance to review everything again. Make sure that all the data you can not afford can be securely backed up, and that you have selected the correct method for deleting and deleting for this task.
When you are sure that everything is ready, right-click on the task in Eraser and select Run Now .
What about Windows Reset?
Windows 10 includes its own reset options, which erase the drives relatively effectively. Although we would continue to recommend using third-party software such as Eraser, the Windows reset and formatting method is still effective if you take a few extra steps. To make sure that your data can not only be deleted but overwritten and not restored, follow the instructions to reset Windows. Then fill the drive with data. You can do this by copying movie files, game installations, or other items that are especially large – hundreds of megabytes or several gigabytes. Copy and paste again and again until the drive is full. Then put it back again.
The drive should be clean enough to dispose of.
Deleting a Drive on MacOS
Step 1: Run the Disk Utility
MacOS 'built-in hard disk wiping tool is fantastic and more than enough for average disk wiping. Access it by booting to MacOS Recovery by turning on and holding your Mac. Command + R. Hold down the display until you see the Apple logo or a globe. The MacOS utility window should open shortly thereafter.
Select Disk Utility from the list of options.
Step 2: Select the disk to be deleted
Select View . from the top menu bar, followed by Show All Devices . In the left menu, select the hard disk to be deleted.
Step 3: Select the deletion options
Select Erase ] in the top menu. Select the new name for the volume after it has been deleted. Select the format APFS unless you intend to install a version of MacOS before High Sierra on the drive (in this case, Mac OS Extended ). For the scheme, select GUID Partition Card .
If you delete an SSD, continue to the next step. If you use a hard disk, you can make the deletion a little more effective. To do this, select Security Options and use the slider on the following page to change the number of passes that the delete tool makes over the drive. More than one is enough and a little over three is probably overkill.
Step 4: Erase the data
If you are sure that you have backed up all the important data (after this step, there is no turning back)) Select Erase.
Destroy the drive physically.
An alternative step to the above-mentioned digital data removal method or a secondary step if you want to double-check that your data can not be recovered. Everyone should physically destroy the drive.
If you are of the practical type, you can drag the hard drives (the actual hard drives that hold the zeros and your data) and grind the surface until they look like a dimple and crater. Another option is to pull a rare earth magnet, such as a neodymium magnet, over the drive plate. That deforms it and makes all data unreadable.
You can also drill holes in the drive if you do not want to bother removing the case.
There are companies that professionally destroy the device. Drive for you while you watch as well. Think "it will melt", but with a much larger mixer.
