DIY Guide: Using Internal Drives as External Storage.
If you want to increase your computer's storage without adding new memory drives, or if you have an old internal hard drive (HDD) or solid-state drive (SSD) lying around, you can convert it to an external drive for file transfers, backups, or extra storage. Converting an internal drive to an external drive is an economical method of increasing storage capacity.

This detailed guide teaches you how to convert your internal drive
into a fully functional external drive.
Step 1: Determine what type of
internal drive
- 2.5" SATA HDD/SSD (Laptop Drive)
- 3.5" SATA HDD (Desktop Drive)
- M.2 SATA or NVMe SSD
- IDE HDD
Step 2: Purchase the Right
Enclosure or Adapter
- 2.5"
SATA SSD/HDD → 2.5" external drive enclosure or a SATA-to-USB adapter.
- 3.5"
SATA HDD → 3.5" external drive
enclosure (requires external power).
- M.2 NVMe or SATA SSD → USB-C or USB 3.1 M.2 enclosure.
- IDE HDDs → IDE-to-USB adapter.
Step 3: Install the Drive Into
the Enclosure
For SATA HDDs and SSDs (2.5"
or 3.5"):
- Open the enclosure (usually with screws or a
sliding mechanism).
- Align the SATA connectors on the drive with those
in the enclosure.
- Firmly insert the drive into the SATA port.
- Secure the drive with screws (if any).
- Close the enclosure.
For M.2 SSDs:
- Open the M.2 enclosure.
- Insert the M.2 SSD into the slot with a little
elevated angle.
- Gently press it down and secure it with the
provided screw or latch.
- Close the enclosure.
Step 4: Connect the Drive to
Your Computer
Now connect it to your computer:
- Use the provided USB cable to plug the enclosure
into a USB port on your PC.
- If using a 3.5" HDD, plug in the external
power adapter with the enclosure.
- Your computer should detect the drive
automatically.
Step 5: Format the Drive (If required)
You may need to format if your drive is not recognized or has old data.
- Press Win + X and select "Disk
Management".
- Look for the new drive in the list (it may be labeled
as “Unallocated”).
- Right-click the drive and select "New Simple
Volume".
- Follow the wizard and select:
- NTFS (best for Windows-only use).
- exFAT (for compatibility with Windows and macOS).
- Click "Finish" to format the drive.
Conclusion
Repurposing an internal hard drive or SSD as an external drive is a great way to use old storage devices. Whether you use it for file transfers, backups, or additional storage, this easy procedure can help you increase storage capacities and save money. Additionally, buying an external drive directly is more expensive than buying an internal drive.
Employing an SSD or internal hard
drive as an external drive is more cost-effective, but it's still advisable to
consider the drawbacks that accompany it like increased wear and tear,
durability, etc. It is advised to check all the factors and choose what fits
you the best.
