How to Convert Internal Hard Drive to External Hard Drive

Are you upgrading your PC with the new hard disk? Are you having a spare hard disk?

How about making that old internal hard disk drive into external hard disk drive? Sounds good?

If your answer is Yes, then this post is for you.

In today’s post, I’ll share the exact steps that I’ve done to convert my old PC’s internal hard disk (no matter it is SATA or IDE (PATA). If these terms are new to you, then read this post) into an external one. Let’s get started.

Convert Internal Hard Drive to External Hard Drive

We don’t need any software to do this. All we need is SATA/IDE to USB 2.0 adapter.

But before you make any sale, you need to remember 2 things:

PC’s hard disk is 3.5 inches

Laptop’s hard disk is 2.5 inches

So, you need to buy the cable as per your device’s HDD size.

I grab the one like this which is compatible with both 2.5 and 3.5 inch HDD drives. This one not only supports disks, but it also supports CD-ROM, CD-RW, DVD-RW, and DVD-ROM too.

Once you have the cable on your hands, now it’s time to do our task. In this instance, I’m sharing the steps to convert the internal HDD (IDE) into external HDD.

First, connect the AC adapter and AC to IDE power converter together.

Connect the end of the AC to IDE power converter with the hard disk.

Now take the USB to IDE/SATA cable adapter. Connect the one end of the adapter to the hard disk and another end with PC.

That’s all. Now you can see the hard disk on your PC.

Alternate Way

You can use enclosures (also known as caddies)​ to do this task and here is the video tutorial.

Final Thoughts

Instead of putting the old hard disk on the shelf, it is better to spend some bucks to make it usable.
