Steps to Take Before Throwing Away Your Old PC

In 2010, the FTC recorded over 250,000 complaints of identity theft in the United States. While many identity thieves still get their information from your paper mail, a stolen purse or wallet, or hacked files online, more and more are starting to glean sensitive information from the hard drives of old computers. If you’re getting ready to toss out your desktop or laptop in favor of a newer model, take these steps to protect yourself from identity theft.

What information might be stored?

Not sure it’s worth all that work to wipe your hard drive? After all, you don’t keep a ton of important information on your computer, so what could a hacker possibly find anyway; and if you’re just donating your computer or selling it for cheap, what are the odds that an identity thief is going to get his hands on it?

The problem with this line of thinking is that often times, your computer has stored information that you don’t even know it has stored.

Common information stored on computers includes account numbers, credit card numbers, passwords, registration keys for software programs that you use, medical information, addresses, and even tax returns – which contain pretty much all the personal information necessary for a someone to apply for a credit card or bank loan in your name!

Keep in mind that many identity thieves will actually buy a used computer – or even steal a donated one – in the hope of gleaning such personal information. This information can be worth thousands of dollars to them and can create a huge headache – and financial problems – for you.

How to get rid of the data

So, before you sell your computer or donate it to your local school system, take these steps to get rid of the data for good:

1. Don’t count of just deleting the files. While you’ll want to delete the files from your computer, this is just the first step to take. Identity thieves are often experts at getting deleted information from hard drives by using specialized software.

2. Save any files you want to keep. Before you wipe your hard drive, you will, of course, want to save any files you want to keep. You can transfer your data to a new computer, burn it to a CD, put it on a USB drive, or put it on an external hard drive – a particularly good option if you need to store a ton of files or information.

3. Use a utility program specifically meant to wipe your hard drive. Local tech stores will sell utility programs meant for this purpose that match up with your specific operating system. The best idea is to get a program that will overwrite or wipe the hard drive several times instead of just once, and you’ll definitely want a program that wipes the entire drive.

If you know your computer has particularly sensitive information on it and you don’t trust a utility program to get rid of the information, you can always destroy the hard drive physically.

Businesses in particular, often use hard drive shredding services, as their computers tend to have lots of personal information on both employees and customers of the business.

Once you shred the hard drive, you can simply sell or donate the rest of the computer without it, and the new owner can then completely replace the hard drive.

Watching for identity theft

Even if you are careful to destroy information on your computer before you sell or donate it, it’s a good idea to be wary of potential identity theft.

Check your credit reports regularly to ensure that everything is accurate. Credit reports are normally the first place you’ll see evidence of identity theft when new accounts pop up that you didn’t open. If you do think you’ve been a victim of identity theft, get identity theft assistance as soon as possible.

Report the problem to the credit reporting bureaus, who will place a fraud alert on your account. Then close the new, fraudulent accounts. Finally, report the fraud to the Federal Trade Commission and your local police department.

If you’ve taken steps to protect your personal information from being stolen, you may never have to deal with the problem of identity theft, but it’s always a good idea to be aware of what you should do if your identity should be stolen.

  1. Great advice, While I would never donate my computer to a school, because then I think it would be more likely to be hacked. What program would you suggest to use to wipe your harddrive.

  2. Good post, Daniela. A lot of people forget that their hard drives could be accessed by other people once they throw it away and sensitive data might be recovered from it even though it has been formatted. I read somewhere that passing the drive through a strong electromagnetic field will ensuring total erasure of all data. Is this true?


    • Hi Jean,

      While it is definitely possible to erase a hard drive using a giant magnet or an electrically-charged magnetic coil (this method is also known as “degaussing”), I wouldn’t recommend it. A powerful magnet in the hands of a novice can completely ruin a computer hard drive (not to mention mess up a computer monitor), so I wouldn’t recommend that method unless you know what you’re doing and can afford to trash the drive anyway.

  3. Hi Daniela, great article, as you point out there are plenty of people ou there who would love to get their grubby little hands on your hard drive. The only way to be sure is as you say is to destroy the hard drive. It’s a shame but for piece of mind that’s all you can do

      There is always the option of format and rebuild – more time consuming, but less wasteful.

      Thanks for adding your view Phil, welcome to the blog 🙂

  4. The thing with this is to remember that when you delete a file your computer only really deletes the link to that file so you can’t see it any more, it’s still there and can be accessed by someone who knows how.

    These programs write over the drive multiple times until the files are eventually overwritten.

    Personally, I would just take the hard drive out before donating a PC to anyone. They’re cheap and easy enough to replace anyway.

  5. One should always wipe their hard drive whenever they come to sell their computer. If I didn’t for example, it would be just my luck that the person I sell it to is an elite hacker! haha.

    Great tips and information here, loving it!
