Following steps to erasing a hard drive is essential to removing all data from a hard drive. Otherwise, some hard drive data recovery processes can restore hard drive information, even if the drive is formatted.
Why you need to erase hard drive data.
Merely formatting a hard drive doesn't erase your hard drive information; it simply renders the file structure null and void, making it difficult to retrieve the info. Anyone with a hard drive data recovery tool can restore the information you overwrite during formatting. To erase a hard drive, you need to use a secure erase tool that not only deletes your data but also overwrites it several times with other data. This additional overwriting garbles the original data so efficiently that it's impossible to restore in a meaningful manner.
Backup any files you want to save.
Before you utilize any erase tools, you'll want to backup any files that you want to save. While most people want to destroy certain files and data by erasing a hard drive, you may find that you want to save certain data before you erase. You won't be able to restore this data when you're done, so back it up before you begin.
Select a data erasing tool.
Decide which data erasing tool you want to use to destroy your hard drive information. You can use a tool like DBAN to erase your hard drive data, or you may prefer something that utilizes the secure erase functionality built into Windows systems. Read reviews, and select a tool that satisfies you with its erasing capabilities.
Install and run the data erase tool.
Once you've selected the tool you want to use, install and run the program. You may be able to download the program online, or you may need to order or purchase the data erase tool that you want to use from a retailer. Once you have it, install it, following the prompts on the install wizard.
Most data erase tools are intuitive to run. Consult the program instructions if you have any trouble. You may need to select how many cycles you want it to run, which determines how many times you erase and overwrite your data. The more times you overwrite it, the lower the chance it can be restored using a hard drive data recovery tool. Ultimately, two or three cycles are typically enough for most home users. Then designate the drive you want to erase, and let it run.
Format your hard drive and reinstall Windows, or destroy the hard drive.
Once your data is erased, you can format your hard drive and reinstall the operating system, pass it on to someone else or destroy the hard drive. Ultimately, if you don't particularly want the hard drive to be usable, destroying it is the best and final way to ensure your data is safe from recovery. However, many people want to re-use an erased hard drive, or pass it on to someone else who could utilize the hard drive; both of these are acceptable options, as long as you've successfully erased the contents.
