It's very common for laptops to crash but still have study files, work documents, or personal photos on them. The problem isn't just recovering the files, but also the risk of incorrect operation that could overwrite data or cause more serious damage to the storage drive. In this article, TipsMake will share how to safely recover data from your laptop's hard drive, helping you find your lost information.
Key points
- Accurately identifying the laptop's fault (screen damage, Windows issue, or physical problem) helps you choose a safe and effective data extraction method.
- Safe ways to recover data at home: Connect an external monitor, use a USB box, use a bootable USB drive, or use recovery software.
- Absolutely do not format, reinstall Windows, or save new files to the faulty drive to avoid the risk of overwriting and permanently losing data.
- Stop attempting to fix it yourself and seek professional help if your hard drive is making strange noises, has been exposed to water, is broken or dropped, or is not fully recognized.
- After retrieving the data, quickly back it up to an external drive or the cloud to prevent the risk of losing it again.
1. Before extracting data, it's necessary to identify what kind of error the laptop is experiencing.
1.1. Laptop screen is broken but the machine is still running.
- Common signs include the power light on, the fan spinning, the keyboard lighting up, or the Windows boot sound still being heard.
- In this case, the data usually remains in the storage drive, as the error lies more in the display part.
- The preferred approach is to connect the computer monitor first. If that doesn't work, you can try removing the hard drive or using a converter box.
The device has a power light, the fan is spinning, etc., but the screen doesn't light up.
1.2. Laptop won't boot into Windows or start up.
- Symptoms include getting stuck on the logo screen, boot errors, entering a repair loop, or a blue screen.
- The problem could lie with Windows, the boot loader, or the partition (hard drive partition); it's not necessarily true that the drive is faulty.
- If the computer still recognizes the drive, there's usually a good chance of copying the files out using a bootable USB drive or by removing the drive.

1.3. The hard drive shows signs of physical damage or serious failure.
- The computer is running unusually slowly, freezes frequently when opening files, the HDD makes clicking noises, or the SSD is not recognized.
- Bad sectors are areas where errors are stored, causing data read and write operations to become unstable.
- With HDDs, strange noises are a high-risk sign. With laptop SSDs , a complete loss of recognition is often more difficult to fix yourself.

3. 5 most common ways to retrieve data from a laptop hard drive
3.1. Connect your laptop to an external monitor if only the screen is damaged.
This method is suitable when the laptop powers on but doesn't display anything. You can try connecting via HDMI , VGA, or USB-C depending on the model. The goal is to access the operating system to copy data to a USB drive, external drive, or cloud storage. If the laptop doesn't automatically display an image, try the screen switching key combination specific to your model.
If your laptop screen is broken, try connecting it to an external monitor.
3.2. Remove the hard drive and install it in another computer.
This method is suitable when the main computer has a serious failure but the drive is still good. Modern laptops typically use 2.5-inch SATA , M.2 SATA , or M.2 NVMe drives . SATA is a common storage connection standard. NVMe is a high-speed SSD standard that runs through the M.2 slot.
You need to check the correct type of drive before removing it. Then, install it in a compatible computer to access and copy the data. Prioritize copying important files first. Do not rush to modify partitions or run multiple diagnostic tools on this drive.

3.3. Using a hard drive enclosure and a USB-to-USB cable.
A hard drive enclosure is a conversion case that turns a laptop's hard drive into an external drive that connects via USB. This is an easy solution for the average user because it doesn't require direct connection to another computer.
You need to prepare the correct type of enclosure for the HDD/SSD and the correct SATA/NVMe standard, another computer that is working stably, and a file storage location to copy data. If the drive is recognized, copy the data first before considering further testing. If the drive is intermittent, makes strange noises, or disconnects constantly when plugged into the enclosure, stop testing.

3.4. Boot from USB to copy data.
This method is suitable when Windows is corrupted but the drive is still recognized. Booting from USB means booting the computer into a different environment, such as WinPE or Linux, instead of the operating system on the hard drive.
The goal isn't to reinstall the operating system, but simply to open the folder and copy the files to another drive. This is useful when the computer is stuck on the logo screen, has boot errors, or won't boot to the desktop. Do not overwrite Windows on the drive where you need to recover data. Doing so could lead to the loss of more files or reduce the chances of recovery later.
Booting from a USB drive allows you to start your computer in a different environment, open folders, and copy files to another drive.
3.5. Use data recovery software when the drive is still recognized.
This method is suitable for accidentally deleting files, minor partition loss, or when the drive is still readable but missing data. Some popular tools include Recuva, EaseUS, and MiniTool. Do not install the software directly on the faulty drive. Do not save the recovery file to the drive you need to recover from. These two actions can easily overwrite data and reduce the chances of recovering files.
Note: Recovery software does not guarantee 100% recovery. Results depend on the extent of overwriting, drive condition, and timing of the process.

4. When should you avoid collecting data at home?
- An HDD making clicking or buzzing noises is usually a sign of a mechanical failure; attempting to read from it only increases the risk.
- The SSD is not fully recognized. In this case, a USB adapter or reinstalling the SSD usually won't solve the problem.
- The socket is burned, broken, or has been exposed to water. Physical damage requires more specialized equipment.
- The drive has BitLocker encryption but no decryption key. Without the decryption key, accessing the data is very difficult.
- The data is too critical to handle, and there's no room for risk. Therefore, a data recovery center should be prioritized from the outset.
Even if the drive has BitLocker encryption, accessing the data without the key is very difficult.
5. Things to avoid to prevent permanent data loss.
- Do not format the hard drive from which you need to recover data. Doing so may cause further loss of file structure.
- Do not reinstall Windows on the faulty drive. The new system may overwrite the old data.
- Do not copy new data to the drive you need to recover. This is the most common mistake that causes overwriting.
- Avoid excessive repeat scans if you suspect bad sectors or physical damage. Each scan can further weaken the drive.
- Do not modify partitions unless you are sure of the cause. Incorrect partition settings can make data more difficult to access.

6. What should we do next after collecting the data?
- Copy all important files to an external drive.
- Save important data to the cloud to reduce the risk of losing it again.
- Check the health of your hard drive using SMART or the manufacturer's basic testing tool.
- If the drive is slow, has a history of bad sectors, or experiences recurring errors, it should no longer be used for important data.

7. Frequently Asked Questions
7.1. Can data be recovered if the laptop screen doesn't turn on?
Yes. If the computer is still running and the drive is working, you can prioritize connecting an external monitor. If that doesn't work, you can remove the drive or use a USB box to copy the data.
7.2. Can a USB enclosure be used if the hard drive is broken?
It should only be used if the drive is still recognized. If the drive is making strange noises, has been dropped or broken, or is not fully recognized, a USB enclosure usually won't solve the problem and may waste time troubleshooting.
7.3. Can recovery software retrieve 100% of the data?
No. The recovery rate depends on whether the data has been overwritten, the condition of the storage drive, and when you start processing.
7.4. Should I do it myself or take it to a technician?
Attempting to fix it yourself is suitable for minor errors, when the drive is still recognized, and the data is not at significant risk. However, if there are signs of physical damage or the files are very important, it's best to have a technician check it.
