How do I set my SSD as the C drive? Posted by u/BlastedUnknown in pcmasterrace

The C drive usually refers to the boot or system drive that contains the operating system or system-related files. Most users find that their C drive runs out of space easily, as Windows updates or cached installations, temporary files, and some apps default to saving on this system partition. Thus, your Windows may become sluggish, and it might even unexpectedly reboot. In this case, you might need to create a new, larger C drive on a HDD or SSD drive.

Notably, SSDs (Solid State Drives) outperform HDDs in terms of read/write speed, durability, and power consumption. As a result, most computer users prefer SSDs over HDDs, and replacing the C drive with an SSD has become a trend in the computing world. In the following sections, you'll learn step by step how to create a new SSD C drive on your computer.

How to Create a New C Drive on an SSD Using Cloning

To set up a new Windows C drive, you could perform a fresh install of Windows on the new SSD, but that would take a lot of time and effort because you'd have to reinstall Windows and all your programs. Fortunately, there's a better option. It's called cloning, and it helps you transfer data from one hard drive to another without reinstalling the operating system or losing your data.

For this, you need to find a reliable disk cloning tool because Windows doesn't have a built-in cloning feature. Disk Copy Tool is a renowned name in the cloning field that can assist you.

This is a hard drive cloning software tailored for Windows users, capable of cloning disks from multiple manufacturers. It lets you clone your boot drive to a new SSD and ensure the SSD is bootable. Plus, with its sector-by-sector cloning function, it can handle drives with bad sectors and seamlessly migrate Windows from an HDD to an SSD or from SSD to SSD without any data loss.

Solid State Drive cloning software can help you migrate the operating system to the new SSD and make the target disk bootable. Whether you want to transfer, clone, back up, migrate, or upgrade your hard drive, a cloning tool can come in handy. Download it to your computer and follow the step-by-step guide below to create a new HDD/SSD C drive.

Notes:
1️⃣ Prepare a new SSD with at least 500GB for future OS updates and app installations.
2️⃣ Make sure to back up all crucial data on the source disk using a free backup tool like Todo Backup to avoid any risk of data loss.
3️⃣ During cloning, you'll need a USB-to-SATA cable to connect the new SSD to your computer.
4️⃣ There's no need to initialize the new SSD as disk cloning software can recognize an uninitialized disk.

Advance notice:

    • Sector-by-sector clone requires the target disk to be the same size or larger than the source disk. Uncheck this if you want to clone a larger hard drive to a smaller one. • All data on the target disk will be erased. Proceed with caution.

Step 1: To start copying/ cloning an entire disk to another disk, click on the disk as the source disk under Disk Mode, and then click Next.

Select the source disk and click Next

Step 2: Select another disk as the target disk.

Select the target disk

Step 3: Check the disk partitions of both source and target disks. You can customize the partition layout on the target disk by selecting "Auto Resize," "Keep as Source," or "Edit Partitions."

When a warning message appears, click OK.
    • "Automatically resize partitions" makes some default changes to the layout on the target disk so that it runs optimally.
    • "Copy as is" does not change anything on the target disk, and the layout will be identical to the source disk.
    • "Edit disk layout" lets you manually adjust/move the partition layout on the target disk.

Check the “Perform this check if the target is an SSD” option for best performance with an SSD.

A warning message will appear, indicating that your data will be lost. Confirm this information by clicking “OK,” and then click “Next.”

Check disk layout

Step 4: Click “Proceed” to officially kick off the job.
