Intro

If your computer’s hard drive has failed or is showing signs of failure, you may still be able to recover your files. Our shop can often recover data from many types of problems affecting traditional spinning hard drives. However, some drives are too severely damaged to recover without specialized equipment.

The sections below explain the types of data recovery we can perform and when it may be better to send your drive to a professional data recovery laboratory. If you’re not sure which option is right for you, give us a call. We can discuss the problem with you and help determine the best course of action.

⚠ Warning:
If the data is extremely important—such as evidence for a court case—send the drive directly to a professional recovery lab. Expect to pay $800 or more per drive.

What Is Data Recovery?

Data recovery is the process of retrieving files from a hard drive that is damaged, corrupted, or no longer working properly. Hard drives use different file systems to organize and store your data, and the recovery process depends on both the file system and the type of problem affecting the drive.

We divide data recovery jobs into four main categories based on what has gone wrong with the drive. Other computer repair shops and recovery services may categorize these problems differently, but this is the approach we use to determine the best way to recover your files.

File Systems

A file system refers to the way data is organized and stored on a storage device. The majority of our data recovery experience is with NTFS and FAT32 but we have worked with other file systems as well.

Windows

Linux

Apple

While Apple is not our specialty, we do have some experience with Apple file systems and their unique challenges. We can read APFS and HFS+ volumes with our specialized tools.

Categories

We categorize recovery into four main types, depending on what’s wrong with the drive. Other shops may use different systems, but the following sections explain is how we categorize our data recovery jobs. The the work gets increasingly complex with each higher category.

Type 0 – Drive Is Healthy but Computer Is Dead (Very Common)

In this case, the drive itself is fine, but the computer isn’t working. We simply remove the hard drive, connect it to another system, and copy the files. This type of recovery usually succeeds 100% of the time, and we’ve done it hundreds of times. This is actually considered a data transfer.

⚠ Warning:
THERE IS NO GUARANTEE ON DATA RECOVERY.

Type 1 – Logical Issues (Common)

Logical problems occur when the drive still spins and powers on, but data is difficult to access. We use several specialized recovery systems to read data from these drives. Often we can recover most of the files, though data stored on bad sectors—tiny damaged spots on the platters—may be lost. Bad sectors can be caused by scratches, dust, or even rust forming inside the drive.

THERE IS NO GUARANTEE ON DATA RECOVERY.

Type 2 – Electronics Failure

When the drive’s circuit board fails, we sometimes perform a board swap using an identical donor drive. The replacement must match the same firmware and board revision. (The customer must cover the cost of the donor drive.)

If this fails, it would require board level work by a professional data recovery lab. This involves de-soldering and transferring small chips that store unique data. This process can work, but not always. If it fails, the issue may be deeper within the drive’s internal components.

⚠ Warning:
THERE IS NO GUARANTEE ON DATA RECOVERY.

Type 3 – Mechanical Failure

Mechanical issues include:

• Drive clicking or grinding sounds
• Stuck or damaged read/write heads
• Drive not spinning up at all

These issues usually require a clean-room environment, which allows technicians to open drives without dust contamination. We do not have a clean-room, though in some limited cases we can attempt fixes in a very clean area for stuck heads. However, we do not replace heads or motors—those must go to a professional recovery lab.

⚠ Warning:
THERE IS NO GUARANTEE ON DATA RECOVERY.

When to Use a Data Recovery Lab

If your drive falls into Type 0 or Type 1, we can usually help. This is what we do the most.

If it’s a Type 2 or Type 3 issue, a specialized lab is the safer option. Labs have advanced equipment, clean-rooms, and firmware tools not available in standard repair shops. This includes situations like fire or water damage, drives that don't spin up, or physically damaged drives. The services can be costly, so it's up to you to decide if the expense is worth it. The drive will be shipped out to a lab and the process may take a while.

Preventing Future Data Loss

In every case, the best protection against data loss is a regular backup plan. External hard drives, cloud storage, and automatic backup tools can save you from expensive recovery costs later. Remember: if you have a reliable backup, data recovery is rarely necessary.
