How to connect a hard drive from a laptop to a computer: all methods with photos and tips

Why connect a HDD from a laptop to a PC and what is needed for this

Pulled out the old one hard drive from your laptop and want to use it on your desktop? Or do you urgently need to copy data from a faulty laptop? Connection HDD/SSD from laptop to PC - the task is easier than it seems. The main thing is to know the nuances: from the type of interface (SATA, mSATA, M.2) until compatible with the motherboard.

In 90% of cases you won't need a soldering iron or specialized software. It is enough to have an adapter on hand for 300–800 rubles or a free one SATA port on the motherboard. But there are pitfalls: for example, wheels with markings GPT may not be detected in older systems with BIOS Legacy, and NVMe drives require protocol support from the PC. Let's look at all the methods - from the simplest to the advanced.

Method 1: Connect via SATA (for desktop PCs)

If your computer is a classic “tower” with free slots, this method is the most reliable and fastest. Laptop hard drive (standard 2.5") connects directly to SATA port motherboard as normal HDD format 3.5". Here's what you'll need:

• ⚡ SATA cable (usually comes with the motherboard or power supply).
• 🔌 Molex/SATA power adapter (if the power supply does not have a connector SATA 15-pin).
• 📏 2.5" drive mounts (or double-sided tape if you don't have a sled).

Algorithm of actions:

1. Turn off your PC and unplug the power cable. Press the power button 2-3 times to remove any remaining charge.
2. Remove the side cover of the system unit. Find a free one SATA port on the motherboard (usually labeled as SATA3_1, SATA2_2 etc.).
3. Connect SATA cable to the port and to the disk. Then connect the power (SATA 15-pin or through an adapter).
4. Secure the disc in an empty compartment (for example, next to the DVD drive) or place it on a non-flammable surface.
5. Turn on your PC. The disk should be detected automatically.

Check for a free SATA port on the motherboard|

Make sure the power supply has a SATA 15-pin connector (or buy an adapter)|

Disconnect your PC from the network before working |

Prepare mounts for a 2.5" drive (sled or tape)|

Check that the disc is not physically damaged (no chips, oxidation)

-->

⚠️ Attention: If the disk is not detected in BIOS/UEFI, check:

✅ Is the mode enabled? AHCI in settings SATA Mode (not IDE or RAID).

✅ Does the disk conflict with another device (try changing SATA port).

✅ Is there enough power (if the power supply is weak, the disk may not spin up).

Method 2: Using a USB adapter (universal option)

Don't want to disassemble the system unit? USB adapter - your savior. This is a small device that converts SATA in USB 3.0/3.1, allowing you to connect the drive like a regular flash drive. Suitable for:

• 💻 HDD/SSD format 2.5" And 3.5" (requires an adapter with external power for 3.5").
• 🔧 Disks with interface mSATA or M.2 SATA (requires special adapter).
• 🖥️ Laptops without free ones SATA ports (for example, ultrabooks).

How to choose an adapter:

Disk type	Required adapter	Speed	Price, ₽
2.5" SATA HDD/SSD	USB 3.0 → SATA (no external power)	Up to 5 Gbps	300–600
3.5" SATA HDD	USB 3.0 → SATA + 12V power supply	Up to 5 Gbps	800–1500
M.2 SATA SSD	USB → M.2 NGFF (B+M key)	Up to 5 Gbps	500–1000
M.2 NVMe SSD	USB 3.1 Gen2 → M.2 (with chip ASM2362)	Up to 10 Gbps	1500–3000

Connection instructions:

1. Connect the drive to the adapter (for M.2 — insert into the slot and secure with a screw).
2. Connect the adapter to USB port PC. For 3.5" drives, first connect the power supply.
3. Wait for the drivers to install (Windows usually installs them automatically).
4. Open Disk management (Win + X → Disk Management) and initialize the disk if it does not appear.

USB 3.0 → SATA (2.5")|

USB 3.0 → SATA (3.5") with power|

M.2 → USB (SATA or NVMe)|

Method 3: Drive Dock (for frequent connections)

If you regularly work with multiple drives (for example, recovering data or testing drives), docking station - the best solution. It allows you to connect HDD/SSD without opening the case, supports hot swapping and is often equipped with additional functions:

• 🔄 Disk cloning (without PC, with a button on the case).
• 🔒 Hardware encryption (for example, for models StarTech or Sabrent).
• 🌡️ Temperature control (fan or radiator for NVMe).

Popular models:

• 💰 ORICO 2139U3 — budget station for 2.5"/3.5" SATA (1000–1500 ₽).
• ⚡ Sabrent EC-DFLT - for M.2 NVMe/SATA with support USB-C 10 Gbps (2500–3000 ₽).
• 🔧 StarTech USB3S2SAT3CB — with cloning function (4000–5000 ₽).

How to use:

1. Insert the disc into the docking station slot (for 3.5" an adapter may be needed).
2. Connect the station to your PC via USB or Thunderbolt.
3. If necessary, press the clone button (if available).
4. The disk will appear in the system as an external drive.

Method 4: Connect via network access (for remote work)

Need to access your laptop drive without removing it? If the laptop is still working, you can connect to it via the network. This method is useful for:

• 📂 Transfer files without a physical connection.
• 🔄 Using the disk as network storage (NAS).
• 🛠️ Disk diagnostics with utilities like CrystalDiskInfo remotely.

Instructions for Windows:

1. On your laptop, open Control Panel → Network Settings → Change advanced sharing settings.
2. Turn on file and printer sharing and disable password protection.
3. Right-click on the drive (for example, D:), select Properties → Access → Share.
4. On PC open Explorer → Network and find the laptop name. The disk will be available as a network folder.

For Linux/macOS:

# На ноутбуке (Linux) расшариваем папку через Samba:
sudo apt install samba
sudo nano /etc/samba/smb.conf
# Добавляем в конец файла:
[shared]
path = /mnt/disk
browsable = yes
read only = no
guest ok = yes
# Перезапускаем службу:
sudo systemctl restart smbd

⚠️ Attention: Network connection is slower than direct connection SATA/USB (1 Gbps maximum vs. 5–10 Gbps). Not suitable for copying large files (>10 GB).

Method 5: Connect M.2 NVMe via PCIe adapter (for speed)

If your disk is NVMe (For example, Samsung 970 EVO or WD Black SN850), and the PC motherboard has a free slot PCIe x4/x16, you can connect it directly via PCIe adapter. This will give maximum speed (up to 3500 MB/s versus 500 MB/s for USB 3.0).

What you will need:

• 🔧 PCIe → M.2 adapter (For example, ASUS Hyper M.2 or Lycom DT-120).
• 🔌 Slot PCIe 3.0 x4 or later on the motherboard.
• ⚡ Disc with key M (for NVMe) or B+M (for SATA M.2).

Step by step instructions:

1. Turn off your PC and disconnect the power.
2. Remove the housing cover, find a free PCIe slot (usually black or blue).
3. Insert the adapter into the slot and secure it with a screw.
4. Install NVMe disk into the adapter connector (at an angle of 30°) and secure with a screw.
5. Turn on your PC. The disk will be detected as normal NVMe-storage

What to do if the disk is not detected in the PCIe adapter?

1. Check if the motherboard supports NVMe (older boards may not have drivers).

2. Update BIOS/UEFI to the latest version.

3. Try another one PCIe slot (For example, x4 instead of x16).

4. Make sure the disk is good (test on another PC).

5. If the adapter has a chip ASM1166, install the driver from the manufacturer's website.

Common mistakes and how to avoid them

Even if connected correctly, the drive may not work. Here are typical problems and solutions:

Problem	Reason	Solution
The disk is not visible in Conductor	Not initialized or formatted	Open Disk management (diskmgmt.msc) and create a partition
The disk is detected, but does not open	Damaged file system (RAW)	Check chkdsk /f or use TestDisk
Disk slows down when copying	Connected via USB 2.0 or a cheap adapter	Use USB 3.0 or SATA
Blue screen (INACCESSIBLE_BOOT_DEVICE)	Boot record conflict	Disconnect the drive from SATA port 0 (first)

⚠️ Attention: If the disk makes clicking sounds or is not detected by any means, do not try to format it - this may worsen data corruption. Contact a recovery laboratory (e.g. ACE Lab or HDD Recovery).

FAQ: Answers to popular questions

Is it possible to connect an HDD from a laptop to a PC without an adapter?

Yes, if your PC has free SATA port and power supply with connector SATA 15-pin. For M.2 NVMe will be needed PCIe adapter.

Why is a laptop disk detected as an "Unknown Device"?

This is typical for NVMe drives, connected through cheap USB adapter. Need an adapter with a chip ASM2362 or JMicron JMS583.

How to copy data from a disk if the laptop does not turn on?

Remove the drive and connect it to another PC via USB adapter or docking station. If the disk is damaged, use utilities like DMDE or R-Studio.

Is it possible to use a laptop disk as a system disk for a PC?

Technically yes, but you will have to reinstall Windows due to driver differences. Disk 2.5" will work slower 3.5" due to rotation speed restrictions.

What adapter is needed for M.2 SATA And M.2 NVMe?

For SATA M.2 any adapter with a connector will do B+M. For NVMe need an adapter with support PCIe (for example, with a chip ASM2362).
