How to prevent data recovery from hard disk drive?
We all know that deleted data can be recovered by free tools and that data could be anything, personal login account and passwords, business sensitive data, private emails, medical and bank information, and any types of files you can find on computer.
Home using computers don't likely have such worries, but for donated computers and recycled computers, recovered data is a threat to previous owners.
How to prevent?
To prevent data recovery from hard disk drive, we need make sure the hard drive or the SSD we donate or sell should be clean, each sector or block on the disk shall be overwritten to government standard. Especially for the charity who had taken donated computers, disks connected to the devices must be clean according to the privacy laws. The following steps would be some help on preventing data from recovery.
1. Download a third-party data sanitation program which has built-in government standard overwriting methods. FYI, ByebyeData Eraser has 14 overwrite algorithms built-in, most of which are government plans.
2. Install the program and Run the software as administrator.
3. In the first window, you can find that ByebyeData Eraser is able to erase files and folders, erase free space, erase entire drive and erase entire disk. For hard drives we're about to donate or give away, Erase entire disk is the best option to prevent data recovery, because this function is to erase everything on the hard drive. But before stepping to that option, we need to create a bootable media to erase the boot disk. So click Bootable media first.
4. Browse a path to store the ISO file ByebyeData about to create, or just use the default path and click Create to begin.
5. Double-click the ISO file on the desktop or the path you specified and insert a blank CD/DVD to burn. If you have USB instead, you can download a free USB ISO file burning tool- Rufus to start.
After the bootable media is created, just leave it in the USB port or the CD-ROM. Reboot and go the BIOS setting, then select Boot from CD, or USB, save and exit, reboot from bootable media. Then you'll see ByebyeData Eraser's main interface. And now we can start to erase data on all disks with the below guides:
1. Click Erase entire disk and choose all the disks in the list, including the boot disk, or the disk you installed Windows.
2. Choose an overwrite plan for the disks, should it be simple overwrite, advanced overwrite, complex or very complex overwrite? Choose it according to your company or university's rules.
3. Click Erase Now and give a Yes confirmation to ByebyeData Eraser so it can start to erase.
