# HDD Repair – Most Common Faults and Solutions

## What to do immediately when your drive fails

- **Turn off the device** – disconnect the computer, laptop or external drive from power. Every second of running a damaged drive can make the situation worse.
- **Stay calm** – in most cases data recovery is possible, as long as the media isn't further damaged.
- **Don't reconnect the drive** – repeated attempts to power on are the most common reason a solvable problem becomes unsolvable.
- **Contact us – [+420 608 177 773](tel:+420608177773)** – we'll advise you over the phone. Free diagnostics and pickup across the Czech Republic and by arrangement from other EU countries.

## Drive repair vs. data recovery – what's the difference

Most people searching for "HDD repair" actually need [data recovery](https://www.exalab.cz/index.php?Itemid=711). These are two different things:

**Drive repair** means restoring the drive to a working state so it functions as before. With modern hard drives suffering mechanical failure, this is almost always impossible – damaged read/write heads, a seized motor or scratched platters cannot be reliably repaired for continued safe use. The exception is simple faults like a broken USB connector on an external drive or a damaged electronics board.

**Data recovery** means extracting your files from the damaged drive onto new, working media. The original drive is no longer used. In most cases, this is exactly what you need – not a repaired drive, but your data back.

## What not to do – most common mistakes

- **Don't reconnect the drive repeatedly** – if the drive clicks, knocks or won't spin, every power-on worsens the damage. Damaged read/write heads can scratch the platters where your data is stored.
- **Don't use software on a mechanically damaged drive** – no program can fix faulty heads or a seized motor. Software only helps with logical issues on an otherwise functional drive.
- **Don't open the drive** – a hard drive requires an ISO Class 5 cleanroom environment. A single dust particle on the platter can destroy your data.
- **Don't put the drive in a freezer** – an old internet myth that in practice causes condensation and corrosion inside the drive.

## Frequently asked questions

#### Can a hard drive be repaired after a fall?

Repaired to work reliably again – in most cases no. But data can be recovered from it with a high success rate. After a fall, the read/write heads are usually damaged, requiring replacement in a cleanroom followed by reading data with specialized tools. The sooner the drive reaches a lab without further power-on attempts, the higher the chance of success.

#### How long does data recovery from a damaged HDD take?

It depends on the type and extent of damage and on the chosen priority level. We offer express service for urgent cases. We'll provide a precise estimate after free diagnostics.

#### How much does data recovery from a damaged drive cost?

The price depends on the type of fault. You'll receive an exact quote after diagnostics, which is free and non-binding. You only pay for successfully recovered data. For indicative pricing see our [price list](https://www.exalab.cz/index.php?Itemid=198).
