Expert Hard Drive Data Recovery

TeraDrive is here to serve Canada by recovering your data from failed and damaged hard drives. Whether the contents are a critical client list for your company, a collection of cherished photographs, or the creative product of years of hard work, it can be absolutely heartbreaking (not to mention disastrous) to lose the files on an external or internal hard drive. 

We have served many companies and individuals across Canada to diagnose hard drive failures and recover data that would otherwise be lost. With tens of thousands successful data recoveries under our belt, we stand by a core philosophy of our company, and our work: ‘Nothing is lost forever!’

Hard drive failures

In most cases, a hard drive will fail in one of two ways. The reasons for these failures differ drastically, and so do our recovery methods. What they share in common, however, is TeraDrive’s ability to identify the problem, and successfully recover your data from the failed disk drive. So what causes a hard drive failure?

Logical HDD Failure

Like a human, you can divide a hard drive’s functionality into two categories, the body and the mind, or the physical and the logical. In basic terms, a logical failure refers to the function of the ‘mind’ of the drive no longer working. In essence, you can plug the hard drive in normally, and it appears to be in working order. But when you try to access the drive’s contents, you cannot view, edit, or transfer the data. What causes a logical hard drive failure? There can be many reasons, including:

  • File deletion (accidental or malicious)
  • A degraded operating system
  • Corrupted file structure
  • Damaged partitions caused by improper disk use or defective software
  • Computer viruses
  • A ransomware attack


When dealing with a logical hard disk failure, we start the recovery process by creating a clone or image of the original disk. From here, our experts can view the bits and bytes that make up the data as a whole, and get to work on extracting and rebuilding what’s been lost.

Physical HDD Failure

Physical failure is a more self-explanatory reason for hard disk failure. This occurs when the hard drive has been physically damaged in some way or stops normal function due to physical reasons. When a Hard Drive fails physically, some of the common signs that will show something is wrong would be loud noises coming from the drive (clicking/grinding), or a complete inactivity when plugged in.  Causes for a physical hard disk failure include:

  • Physical impact, such as dropping or knocking the hard drive over
  • Voltage spikes, such as a power surge
  • Water damage
  • Fire damage
  • Natural physical deterioration at the end of a hard drive’s lifespan
  • Improper removal of the drive from your system
  • Opening the drive in a non-sterile enviroment

The exact reasons for hard disk failure can vary. Regardless of what’s physically gone wrong in your hard drive, TeraDrive’s stellar track record makes us the obvious choice for data recovery from all malfunctioned disks. No matter how complex the task, TeraDrive’s expert team and record high success rate pose your best shot at a full data recovery.

recovery services

TeraDrive’s recovery service encompasses all kinds of hard disk damage. We operate the most sophisticated data recovery laboratory of its kind in all of Canada, with a cleanroom compliant with the extremely strict CLASS 100 standards. We also use exclusive proprietary software developed in-house, allowing us to offer seamless and effective data recovery you can’t find anywhere else. 

We’re here to help you with any of the following hard drive issues:

  • Deleted or corrupted files or partitions
  • Inaccessible internal and external drives
  • Physically damaged or clicking hard drives
  • Corrupted or formatted file systems
  • OS issues, non-bootable systems
  • Electrically damaged drives
  • Failed HDD Firmware
  • Any other issue that prevents you from accessing the data on your internal or external Hard Drive

Our Data Recovery Process

It begins as soon as you have contacted us about your problem. As a first step, we will help you to get your drive to our lab, either by directing you to your nearest drop-off location or by providing you with a complimentary courier service to pick up your disk from your home or office. Once we’ve received the damaged hard drive, we begin the work of inspecting the drive in our lab in order to best understand the type of malfunction and to provide a quote. From there, within 48 hours of submitting your device, you’ll receive a comprehensive analysis indicating the exact condition of the drive, turnaround time for recovery, and the best possible quote.

Once you’ve received our report, it’s over to you to approve the quote. If approved, our team will start to work on your device using as soon as possible. You will receive frequent updates as the work progresses.

Upon completion, we will send you a file list with the names of the files and/or folders recovered. The list will show you all the data recovered, including the locations and conditions of the files. We have a 96% success rate with HDD recovery, so most of the time, you will see all your files in the list we send.

And the best part? Our “No Data No Fee” Policy — if, in any event, we’re not able to recover your data, it just wouldn’t be right to ask for payment. That’s how confidently we stand by our recovery service.

If you’ve experienced data loss through a hard drive malfunction, whether accidentally formatted or dropped, you understand what a blow it can be. But don’t give up! Instead, give TeraDrive a call, and let us get to work on recovering what’s been lost.

What's inside a hard drive?

At the core of every hard drive lies a marvel of modern technology that efficiently stores and retrieves your digital data. A hard drive operates through a series of precise mechanical and magnetic processes, creating a seamless dance between hardware and data.

  1. Platters and Spindles: Imagine a stack of circular disks known as platters. These platters are coated with a magnetizable material. The platters are stacked on a central spindle that allows them to spin at high speeds, often thousands of revolutions per minute (RPM).

  2. Read/Write Heads: Hovering just above and below the platters are the read/write heads, which are minuscule electromagnetic devices responsible for reading and writing data. They are attached to an armature that positions them precisely over the desired location on the platters’ surfaces.

  3. Magnetic Encoding: Data is stored on the platters using a binary system of 1s and 0s. The read/write heads generate small magnetic fields that magnetize specific areas on the platters, encoding the data. Reading involves detecting the magnetic orientation of these areas.

  4. PCB (Printed Circuit Board): In charge of connecting the drive to your PC, powering it on and off, moving the data to and from the drive, and serving as the brain of the device.
