Data Recovery by Device

External Hard Drive Data Recovery

External hard drives have come a long way in recent years. The products on today’s market offer a fantastic blend of capacity, portability, speed, connectivity and ruggedness. But even with all those qualities, data loss can still happen. When an external hard drive fails, you may lose access to precious memories and critical business files, and that can be disruptive and devastating. Fortunately, there are ways to regain access to the data you need.

Customized External Hard Drive Recovery

We understand that data recovery incidents come in all shapes and sizes.

Ontrack’s engineers are equipped with the expertise to successfully recover data from external hard drives that have fallen victim to circumstances ranging from mechanical failure and accidental drops to fire and water damage.

The Difference Between a Hard Drive and an External Hard Drive

Unlike general hard drives (HDDs) or solid-state drives (SSDs), external hard drives connect to your computer via a USB.

Their portable nature makes them easy to use and convenient for transporting data between machines, however, it also creates a large risk for data loss due to being continuously plugged and unplugged to various devices and dropped or roughly handled.  External drives often employ encryption to protect the data that is stored on the drives and Ontrack has developed tools to help recover data from these special drives.

What Causes Data Loss?

Determining the cause of data loss is always the first step in a successful recovery process.

This is because the cause (even more than the symptoms) will help you and any experts you speak with to identify the course of action that:

  1. Is most likely to be successful
  2. Will get the largest volume of lost data back (or the most valuable data)
  3. Is most time-efficient for you or your provider
  4. Is most cost-efficient for you

Aside from accidental deletion, which is pretty self-explanatory (and often straightforward to rectify), file corruption is one of the most common and relatable issues.

This happens when the data within a file or storage device is altered from its original state. That forces it to either behave differently (for example, an image file might suffer from reduced quality or missing pixels) or become completely inaccessible. We count both as data loss.

Common causes of hard drive corruption

Corruption happens for a number of reasons.

Age

Corruption is more likely to happen on an older hard drive. This is because the data within it degrades over time to the point where files become unreadable. This kind of degradation can happen during operation or even on a storage device that is rarely used.

Malware/viruses

Despite what you might read in ransomware emails, viruses cannot physically damage your storage device. However, they can damage the data within your storage device enough to make it unreadable.

Interruption during writing

Anything that disrupts the writing process (copying files, saving document changes etc.) can cause data to become incomplete, making it inaccessible or compromised. Common examples of causes include:

  • A sudden loss of power (hence why most operating systems ask you not to power off when installing or updating a program)
  • Impact damage from a drop, even a small one
  • Extreme temperatures (both hot and cold)
  • Unplugging a drive while it is in the process of writing data

Common symptoms of hard drive corruption

It’s unlikely that files will just go missing as a result of corruption. You’ll usually notice other symptoms, which can include:

  • Sluggish performance: Files take longer to load, save or copy
  • “Blue screen of death” (BSoD): The operating system fails to boot up (this happens when your operating system files are stored on the corrupted device)
  • The drive isn’t recognized: Nothing happens when you connect your device to a computer
  • The Operating System may prompt to run CHKDSK or other file system repair tools.

Mechanical failure

External hard drives (including both SSDs and HDDs) can also suffer mechanical failures that stop them from functioning correctly and prevent file access. Examples of mechanical failures include head crashes and motor failures. Again, these become more likely as a device gets older as the hardware components within it degrade, although failure can also be caused by physical damage like a drop or exposure to extreme conditions. Due to their portable nature, external drives are also far more prone to damage from bumps or drops than a drive that’s stored inside a physical computer.

You may experience symptoms similar to those above, although mechanical failure tends to result in a device making clicking and/or grinding noises. Listen carefully to your device as it may not always be obvious when this is happening.
