How Long Will My Hard Drive Last?

Backblaze is a company that has been performing data backups to hard drives for several years. Their server rooms consist of literally thousands of hard drives, which gives them a unique opportunity to study drive lifetimes.

Backblaze also studies failure rates of hard drives by model number and manufacturer and publishes a quarterly report. In a study they did in 2013, their data showed that after 4 years of use, 20% of all hard drives failed. They estimated that after 6 years, half of all hard drives in use worldwide would fail.

I have a customer who is still doing her company bookkeeping on a 12-year-old hard drive. I had another customer recently give me a 20-year-old computer running Windows XP and its hard drive fired right up. So obviously, many drives will run for much longer than 6 years without having any major issues. But let’s remember that hard drives are mechanical devices that will all fail eventually, so a current backup is a good idea too.

If a drive does fail, you can sometimes recover data from the damaged drive, but it can be an expensive and time-consuming process. It’s a LOT easier and much less expensive to back up your files and swap an older working hard drive with a new one than it is to try to recover your data from a crashed drive.

If you’re using an older computer with an older hard drive, I can replace that old hard drive with a new one and copy your data over for you. In most cases, people also see an increase in speed with a new drive.

Trust me, it’s better to do it before it becomes a crisis.

Backup and Wipe

At some point, you will replace your computer with a shiny new one. If you decide to sell, donate or dispose of the old computer, it’s important to properly wipe the data off your old hard drive first.

A 2017 study from the National Association for Information Destruction found that improper data erasure is very common.

When a hard drive is formatted, you’re usually only deleting the file system, making the data invisible but not gone. A file recovery program or special hardware can often recover the information.

To test this, NAID bought several hundred devices sold on sites like eBay, and they were able to recover vulnerable personal information on 40% of the devices and drives. This included the recovery of passwords using basic methods and free tools from the internet. 

Sensitive files that can potentially be recovered from an old hard drive include financial and tax information, work project files, personal photos and videos, medical documents, passwords, your web browsing history, and more. If you don’t want these files and information falling into the hands of your computer’s new owner, or worse yet, a hacker, you need to perform a secure wipe of the drive.

PC Overhaul can securely erase hard drive’s to Department of Defense standard DoD 5220.22-M. This overwrites every area of the hard disk 3 times with randomized data, ensuring nothing can ever be recovered.

But before I wipe your old hard drive, we should back up your data first. Very often, people think there’s nothing important on an old computer. Later, after the computer is gone, they sometimes realize they are missing files that may have been left on the old computer. Don’t make this mistake!

I can back up all your important files to an external drive or the cloud, then securely wipe your hard drive with professional-grade software and provide you with a certificate to verify the process.

And if you are going to re-sell or donate the machine, I can also reload Windows on the computer and perform some tweaks to the system to make it better than brand new.

Creating A Data Backup Plan

We live in a digital world, where the only copy of our irreplaceable photos or important business data sits on a mechanical hard drive that can fail at any point without warning. Yikes!

Data loss can be devastating personally and professionally, and although data recovery is sometimes possible, the process is expensive and can’t always recover all of your files.

Creating a data backup plan can save you time and money if you have a hard drive crash. It may seem complicated, but it can be done fairly easily using the 3-2-1 backup strategy.

Cloud storage can be used as part of a 3-2-1 backup plan

The 3-2-1 Backup Strategy

The 3-2-1 backup strategy is made up of three rules, which are:

  • Three copies of your data- Copy 1 is your original data (your primary copy). For most people, this data is located on the C drive of their computer. You should also have at least two backup copies of this data.
  • Two different storage types- Both backup copies should be kept on two separate storage types to minimize the chance of failure. Storage types could include a USB flash drive, internal hard drive, external hard drive, removable storage drive, DVD, tape or cloud backup.
  • One copy offsite- At least one backup copy should be located offsite, away from your primary copy. This protects you from a natural disaster that could destroy all the local copies.

For example, let’s say your files are on the hard drive on your home computer. For your first backup copy, you can use an external hard drive, which you can easily access if you need to retrieve a file. You could then set up a cloud backup as your second (archive) backup copy.

If your computer hard drive fails, you can get your files back from either of your two backups. The external hard drive should be your first choice, because copying is much faster via USB cable than downloading from the cloud over your internet connection. But in the event your house catches on fire, or you have a power surge that wipes out both the computer and the external drive, that cloud storage backup is going to be a lifesaver (and worth every penny).
