Overview on wiping a hard drive

It's common to most users to sell or give away computer or hard drive when they want to dispose of old device or upgrade to new ones. You may have already formatted the hard drive or deleted files on it in order to erase sensitive personal data and avoid becoming the victim of identity theft.

However, the fact is that wiping out a hard drive is not as easy as deleting data or formatting hard disk. Simply deleting files by Shift + Delete or emptying the Recycle Bin does not permanently clear data, as deleted files can easily be recovered by recovery software. Formatting a hard drive does not completely erase data either. Though operating system cannot see deleted or formatted data and the drive looks empty, average users are able to get back lost data easily with the help of hard drive recovery software.

If you view tech forums or comminutes online, you can see lots of users looking for an easy way to clean storage devices, and here is one of them:

'What is the best way to clean the hard drive of my laptop? I'm going to selling it to someone but want to ensure all personal files are securely erased. What I want to do is cleaning hard drive completely and reinstalling Windows 7 (its configurations does not suitable for Windows 10). Everything on the hard disk has been backed up to my external hard drive, I'm hoping one of you here can tell me how to clearing PC step by step? I know how to install Windows from CD but have no idea how to safely wipe hard disk. Many thanks!'

Why deleting and formatting is not the same as erasing hard drive?

Are you one of those who hold the view that deleting a file is similar to erase it? If yes, you should take a fresh look at this issue. We'll explain reasons in an easier manner.

Hard drive is a kind of storage devices which is used to store digital data. Files are stored on the surface of magnetic and rotating platters in hard disk case. Hard disk changes the magnetic property of platter surface to 1 or 0 when reading or writing data. Thus all data on hard drive will be finally stored in the form of basic binary data, for example, when system saves data like photos, music, etc. on hard drive, rows of zeros and ones are recorded on platters.

When a file is deleted, those ones and zeros of that files stays unaffected, for only a pointer indicating the file is being deleted. Therefore, the recovering deleted files is available before file data gets overwritten or damaged. What about disk formatting? Formatting works in a similar way, as it does not actually wipe data. Formatting disk or partition looks like tearing the contents of a book without disturbing actual chapters of the book. Recovery software is also able to retrieve lost files from formatted disk.

How does hard disk wiping works?

You may wonder how disk wiping works since deletion and formatting does not work on permanently clean hard drive. Apart from physical damage to hard drive, we can completely remove data with disk wiping technology.

As we've mentioned above, to completely erase disk, we should remove those binary data, which means overwriting those zeros and ones with new data. Once binary data of a file is replaced and overwritten by new data, it cannot be recovered any more. Some professional disk eraser software is able to filling up disk with zeros or random information sector by sector, ensuring no data can be recovered from a wiped disk.

What to do before wiping a hard drive?

Some preparatory work should be done before wiping computer hard drive in order to make sure the disk wiping can be completed without interruption or causing extra issues.

• Download and install hard drive wipe software. If you plan to clean hard disk on your own, a disk wipe tool is necessary. You should select one easy-to-use and effective tool for the task. If you want to wipe the entire computer, you should make sure the software can work on bootable drive.
• Ensure battery is full. If you want to wipe a laptop, you should make sure the battery is well charged or connected to power. If power goes out during disk clearing, it might spell disaster to the drive.
• Backup your data to a different hard disk. When you wipe your computer, everything on it will be lost, thus you should back up any files you want to keep to another hard drive. You can clone hard drive or just copy & paste files to that disk.
• Remember to save software serial numbers. Those applications you bought will be lost after wiping your PC, and you need to reinstall them to new hard drive. Do not forget to record each program's serial number so that you can activate them after reinstallation.
• Download drivers. If you are going to reinstall operating system after hard drive is completely wiped, you may need to download necessary drivers for new system. You can go to official web site of the device and download the latest drivers.
• Prepare a bootable disk. If you are wiping computer's main hard disk, you'll have to carry out the task without booting system, such as under WinPE. In that case, a bootable USB drive or CD is needed.

Once everything gets ready, you can start erasing computer hard drive or external disks. The rest part of this instruction will show you how to wipe a hard drive, external disk, SD card or flash drive via different ways.

Case #2: How to wipe computer system hard drive?

In this example, you can learn how to wipe a computer's main hard drive where Windows is installed. Operating system does not allow to erase system while it is running, and we can only wipe non-system partitions. In this situation, we can erase the hard disk in Pre-OS environment, for example Windows PE.

Case #3: Wipe a single file or folder on hard drive

Erasing an entire hard drive takes too much time, and you don't have to do that if you just want to erase certain existing files on the disk. On account that deleting files by emptying Recycle Bin does not wipe data complete, we should do extra operation to make files unrecoverable. Files deleted in this way cannot be recovered by any recovery software or professionals. Let's have a close look at how to wipe files and folders:

Step 1. Launch DiskGenius again, and locate files you want to permanently delete. Select those files and right-click them to choose 'Delete Files Permanently'.

Step 2. Click 'Permanently Delete' button on the popped-up window.

In order to completely delete the file, the application will refill hard drive sectors taken by the file during deletion. By default, it overwrites data by filling zeros which can be modified to random data as well. Besides, you should select 'Delete Directory Entry' option on FAT partition (and the option will be 'Delete File Record in $MFT' on NTFS partition).

Step 3. Click 'Delete' button to confirm the action to be done.

When selected files get deleted, you can continue to delete other data on your computer.

Case #4: Erase deleted files only without affecting existing data

Erasing free space on hard drive overwrites lost files, which does not disturb existing files on the disk. This solution applies to those who just want to overwrite lost files only in order to make lost data unrecoverable. For instance, you've formatted hard drive and reinstalled operating system, what you need to do is erasing all disk area except system; or you've deleted sensitive using Shift + Delete, and want to make sure they are no longer recoverable without affecting existing data.

Step 1. Start Eassos DiskGenius, click 'Tools' menu and select 'Erase Free Space' item.

Step 1. Use a screwdriver to remove all screws on the hard drive case. Then you'll be able to remove enclosure and the main circuit board.
