Transferring data from a desktop computer's hard drive to a laptop is a task that users face when upgrading a PC, backing up or restoring files. The main difficulty is that HDD/SSD from desktop not intended for direct connection to portable devices. However, a solution exists: it is enough to use adapters or external adapters to convert the interface SATA or IDE to standard USB.

In this article, we will analyze all the available connection methods - from budget adapters to universal docking stations, and also look at typical errors (for example, when the disk is not detected by the system) and ways to eliminate them. We will pay special attention interface compatibility: not every adapter is suitable for M.2 NVMe or outdated IDE-disks. If you plan to work with large amounts of data (for example, transferring projects or archives), it is important to estimate the transfer speed in advance - it can differ by 2-5 times depending on the chosen method.

1. What tools will you need to connect?

Before you start connecting, make sure you have everything you need. The main component is adapter or box, which converts the hard drive interface to USB. They can be divided into three categories:

  • 🔌 SATA-to-USB adapters - simple adapters for 2.5" And 3.5" USB powered drives (only for 2.5") or external unit (for 3.5").
  • 📦 External boxes (enclosure) — boxes with an adapter inside, protecting the disk from damage. Available for one disk or with RAID support.
  • 🖥️ Docking stations - advanced devices with support for multiple drives, UASP (data transfer acceleration) and additional ports (USB-C, eSATA).

You may also need:

  • 🔋 Power supply for 3.5" drives (if the adapter does not support USB power).
  • 🔧 Screwdriver (for removing the disc from a PC or installing it in a box).
  • 💽 Cables: USB 3.0/3.1 Type-A or Type-C (depending on laptop ports).
📊 What type of hard drive are you planning to connect?
  • 2.5" SATA (from laptop)
  • 3.5" SATA (from PC)
  • M.2 NVMe/SSD
  • IDE (obsolete)
  • I don't know

If you are working with M.2 NVMePlease note: not all adapters support this protocol. For example, cheap adapters often only work with M.2 SATA, and for NVMe requires a separate chip (for example, ASM2362 or JMS583). Check specifications before purchasing!

2. Method 1: Using a SATA-to-USB adapter

The most inexpensive and universal method is connecting via an adapter. It is suitable for 2.5" And 3.5" SATA drives, and also for some M.2 (subject to compatibility). Let's look at the process step by step:

  1. Disconnect your PC from the network and remove the hard drive. For 3.5" disks, unscrew the fastenings to 2.5" - carefully pull it out of the slot.
  2. Connect the drive to the adapter:
    • 🔌 For 2.5": insert into the connector SATA and connect to your laptop via USB.
    • 🔋 For 3.5": additionally connect the power supply (usually included).
  • Turn on your laptop. The system should automatically detect the new device.

    • ☑️ Preparing the adapter for use

    Done: 0 / 4

    If the disk is not detected:

    • 🔄 Reconnect the adapter to another USB-port (preferably 3.0 blue).
    • 🖥️ Check it out Device Manager (on Windows): If there is an exclamation mark next to the drive, update the driver.
    • 🔧 For Linux/macOS run in terminal: 
      lsblk

      or

      diskutil list

      to make sure the system sees the device.

    ⚠️ Attention: Some cheap adapters do not support disks larger than 2 TB. If your HDD is larger, look for models that support GPT And UASP (For example, Sabrent EC-UASP or ORICO 2139U3).

    3. Method 2: External hard drive box

    If you plan to frequently connect the drive to your laptop, it is more rational to use external box (enclosure). It protects the HDD/SSD from dust, shock and overheating, and also simplifies transportation. Boxes are:

    • 📦 For one disk - compact, with support USB 3.0/3.1 (For example, ORICO 2599U3 for 2.5" or Sabrent EC-HDD2 for 3.5").
    • 🔄 RAID enabled - to create arrays (for example, Mediasonic ProBox for 2–4 discs).
    • 🔥 With active cooling - for 3.5" disks that heat up during prolonged operation.

    Connection instructions:

    1. Disassemble the box (usually the cover can be removed without tools or using a screwdriver).
    2. Place the disk in the slide, secure with screws (included in the kit).
    3. Connect the box to your laptop. For 3.5" models, do not forget about the power supply.
    4. Wait for initialization. B Conductor (Windows) or Finder (macOS) a new volume should appear.
    Boxing type Max. speed UASP support Price (approximate)
    ORICO 2599U3 (2.5") 5 Gbps Yes 1 200–1 500 ₽
    Sabrent EC-HDD2 (3.5") 5 Gbps Yes 2 000–2 500 ₽
    Mediasonic ProBox (2×3.5") 10 Gbps (USB 3.1) Yes 5 000–7 000 ₽
    UGREEN 1065 (M.2 NVMe) 10 Gbps Yes 1 800–2 200 ₽

    Critical detail: if you connect a drive with an OS installed (for example, Windows), do not run it on another PC without first preparing it. This may result in driver conflicts or corrupted system files. It's better to copy the data you need and then format the drive.

    4. Method 3: Multi-drive docking station

    Docking stations are a professional solution for working with multiple disks at the same time. They support:

    • 🔄 Hot swap (connection/disconnection without turning off the PC).
    • 🚀 UASP - a protocol that speeds up data transfer by 20–30% compared to conventional USB 3.0.
    • 🔧 Disk cloning (some models, e.g. StarTech USB3S2SAT3CB).

    Examples of popular models:

    • Sabrent DS-UC3B — support 2.5"/3.5" SATA And UASP, speed up to 5 Gbps.
    • ORICO 6528US3-C - two-slot station with USB-C and support NVMe.
    • StarTech USB3S2SAT3CB - with cloning function and hardware encryption.

    How to use the docking station:

    1. Connect the station to your laptop via USB 3.0/3.1 or Type-C.
    2. Insert the disk into the slot. For 3.5" drives, connect the power supply.
    3. If the station supports RAID, set the mode in the menu (for example, JBOD for independent disks).
    4. The disk will appear in the system as an external drive.
    💡

    If the docking station does not detect the drive, try updating the device's firmware. Manufacturers often release patches for new HDD/SSD models. You can download the firmware on the official website (for example, for Sabrent - on the product support page).

    5. M.2 NVMe/SSD connection via USB

    M.2 NVMe - the fastest type of drive, but its connection is via USB has nuances. The point is that NVMe uses the PCIe protocol, not SATA, so a regular adapter will not work. You will need a specialized device with a converter chip (for example, ASM2362 or JMS583).

    Step by step instructions:

    1. Remove M.2 disk from the PC (unscrew the screw on the motherboard).
    2. Insert it into the adapter, securing it with a screw (usually included in the kit).
    3. Connect the adapter to the laptop via USB 3.1 Gen 2 or Type-C (for maximum speed).
    4. B Device Manager check that the disk is detected as NVMe Controller.

    Data transfer speed will be limited by bandwidth USB:

    • 🔥 USB 3.1 Gen 2 (10 Gbps) - up to 1,000 MB/s (actually ~800–900 MB/s).
    • ⚡ USB 3.0 (5 Gbps) - up to 400–500 MB/s.
    • ⚠️ USB 2.0 - no more 40 MB/s (not recommended for NVMe).
    Why is NVMe over USB slower than M.2?

    Even when connected to USB 3.1 Gen 2 (10 Gbps), actual speeds are limited by the overhead of the NVMe→USB protocol. For example, disk Samsung 980 Pro in the M.2 slot it shows 7,000 MB/s, and via USB - a maximum of 900 MB/s. The quality of the adapter also affects: cheap models can reduce speeds to 300–400 MB/s.

    6. Connecting legacy IDE drives

    If you need to connect IDE disk (for example, from an old PC from the early 2000s), you will need a special adapter IDE-to-USB. These devices are less common and more expensive SATA- adapters. Examples:

    • Sabrent USB-IFL — support 3.5"/2.5" IDE And SATA.
    • StarTech USB2IDE - only for IDE, with external power supply.

    Connection features:

    • 🔌 IDE drives always require external power (even 2.5").
    • 🔧Adjust the jumper (jumper) on the disk to mode Master (if you connect one drive).
    • ⚠️ Speed limited USB 2.0 (up to 40 MB/s), since IDE does not support UASP.
    ⚠️ Attention: Old IDE drives often have bad sectors. Before copying data, check with chkdsk /f (Windows) or fsck (Linux/macOS). If the disk makes a grinding noise or is not detected, do not try to repair it yourself - contact a service center.

    7. Common mistakes and their solutions

    Even if the connection is correct, problems may occur. Let's look at the most common ones:

    Problem Possible reason Solution
    Disk is not detected Lack of nutrition (especially for 3.5") Use a power supply or Y-cable for additional USB-port
    The disk is detected, but does not open File system ext4/APFS (not readable on Windows) Use Linux Reader or connect to macOS/Linux
    Low transfer speed Connection to USB 2.0 or lack UASP Reconnect to USB 3.0+ or update the adapter driver
    The drive appears as RAW Damaged file system Recover data via TestDisk or format

    If the disc makes unusual sounds (clicking, grinding), turn it off immediately. These are signs of mechanical failure and continued use may result in permanent data loss.

    💡

    Before connecting a disk with important data, always check it for bad sectors. On Windows this can be done via CrystalDiskInfo, in Linux - with the command smartctl -a /dev/sdX.

    FAQ: Frequently asked questions

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

    No, for connection SATA or M.2 drive always requires an adapter/box. An exception is if your laptop supports connecting a second drive to a special slot (for example, some models Lenovo ThinkPad or Dell Precision), but this is rare.

    Why is the disk detected, but the files are not copied ("Access Denied" error)?

    This has to do with access rights. On Windows try:

    1. Right click on the disk → Properties → Security → Advanced.
    2. Click Change permissions and add your account with full rights.

    On Linux use chmod or mount the disk with the option uid=1000.

    Which adapter should I choose for M.2 NVMe?

    Pay attention to models with a chip ASM2362 or JMS583, for example:

    • UGREEN M.2 NVMe Enclosure (USB-C, 10 Gbps).
    • Sabrent EC-SSDN (USB 3.1, support PCIe 3.0 x4).

    Avoid adapters without specified support NVMe - they only work with M.2 SATA.

    Is it possible to connect a Windows drive to a Mac and vice versa?

    Yes, but there are nuances:

    • 🖥️ Windows disk on Mac: NTFS read-only supported. To record, set Paragon NTFS or Tuxera NTFS.
    • 🍎 Mac disk on Windows: HFS+/APFS cannot be read without additional software (for example, HFSExplorer).

    Better to use exFAT or FAT32 for cross-platform compatibility.

    What should I do if the adapter gets hot?

    Overheating of the adapter may result in slow speed or drive shutdown. Solutions:

    • 🔥 Use an adapter with an aluminum housing (such as ORICO or Sabrent).
    • 💨 Connect an external cooler (if you are working with 3.5" disk).
    • ⏸️ Take breaks when copying large files (>50 GB).
