How failure develops depends on the device type
HDD
Hard drives can fail in different ways. Some stop working suddenly, while others degrade gradually over time. Even when a failure appears abrupt, it may be the final stage of underlying physical degradation.
By the time a drive reaches a lab, it may have already been restarted multiple times, scanned, or accessed despite errors. This is common. What matters now is how much of the disk surface can still be read before the condition deteriorates further.
Typical Signs
Slow or intermittent access
Freezing during file operations
Missing or corrupted files
RAW or unformatted volumes
Clicking or repeated seeking
SMART errors or bad sector warnings
Key Recovery Factor
When it comes to Hard Drive Recovery, the decisive factor is the drive’s current physical readability, not the original failure symptom.
SSD
SSD failures behave differently. A drive can become inaccessible without warning, even if it worked normally moments before. Like modern hard drives, SSDs actively modify their internal structures. Controller processes like TRIM and background cleanup may continue altering or erasing data during repeated power cycles.
Typical Signs
Not detected or showing 0 MB
Unallocated or empty after failure
Freezing or disconnecting during access
Failure after an update or power loss
Key Recovery Factor
SSD data recovery depends on internal state changes, not visible errors.
RAID / NAS Systems
RAID failures are rarely caused by a single event. Most data loss happens after the initial failure — during rebuilds, repair attempts, or repeated system access.
Once redundancy is exceeded, the array state becomes unstable. Actions meant to “fix” the system can overwrite or destroy critical reconstruction data.
Typical Signs
Degraded arrays or multiple drive failures
NAS offline or unstable
Rebuild started or suggested
“Initialize” or “repair” prompts
Key Recovery Factor
RAID data recovery depends on preserving the original array state, not restoring operation.
Dedicated service
Only a few competitors can match our data recovery capabilities
Tools alone do not make a data recovery company. We do have the best tools, but what really matters is experience, procedures, steady hands, problem-solving skills and sometimes just intuition. That is what we offer. If you want your files back, you’ve come to the right place.
Vital Data Recovery specializes in recovering files from all types of RAID, hard drives, SSDs, flash media and other storage. We have been providing data recovery services Canada-wide and worldwide from our Montreal data recovery laboratory for over 20 years.
Our service starts with a free estimate. We will only proceed with data recovery upon your approval. We are confident in our abilities to recover your files and offer a "No Data, No Charge" policy. In other words, if your files are not recoverable you will not be billed. In the case of an emergency, we can complete the job as fast as 24–48 hours — the quickest turnaround in the industry.
Our expertise lets us handle virtually any request, from the simplest to the most complex cases. We offer the most technologically advanced hard drive data recovery available. If it is still possible to recover your files, we can do it. If another expert has told you that your files are unrecoverable, send it to us for a second opinion. We have a genuine appreciation for the vital nature of your information — whether personal or business. Data loss can be reversed with one call to our Montreal data recovery lab.

How to Get Started
Please fill out our Request Evaluation form first. Then drop off your device at our Montreal lab in NDG, or send it via Purolator or Canada Post.
Most evaluations are completed within 24 hours. After evaluation, we explain what failed, what recovery may involve, and provide a fixed quote. Then you decide how to proceed. What can be recovered becomes clear during recovery.
