How do I use a new disk for storage?

 

I just installed a new disk on my Windows 10 desktop for storing files and backups, but it’s not showing up in File Explorer. I’m not sure what steps I need to take to make it usable. Any help would be appreciated!

Adding a new disk to your PC is a great way to expand storage and improve performance. However, simply installing a new hard drive or SSD doesn't mean it's ready for use. Setting up a new disk involves a few key stages. In this section, we'll guide you through the entire process step by step.

Stage 1. Install a New Disk

Before you can use a new disk for storage, you must physically install it into your PC or connect it via USB if it's external. This step is crucial because if the drive isn't correctly connected, Windows won't detect it.

➤ For a desktop:

Step 1: Shut down your desktop and unplug the power cable. Then, open the computer case and locate the hard drive bay.

Step 2: Find the hard drive mounting bracket or tray, and use a screwdriver to remove it from the case.

Step 3: Remove the old hard drive (if any) and install the new one in the tray or bracket.

Step 4: Connect the new hard drive to the motherboard using a SATA data cable, and attach the power cable as well.

Step 5: Once the new hard drive is securely installed and connected, reattach the case cover.

➤ For a laptop:

Step 1: Shut down your laptop completely and disconnect it from the power supply. Make sure to remove the battery if it’s removable.

Step 2: Use a screwdriver to carefully open the back cover of the laptop.

Step 3: Locate the hard drive bay inside the laptop.

Step 4: Gently remove the old hard drive and replace it with the new one. Secure it with screws, then reattach the back cover.

Stage 2. Initialize the Disk

After successfully installing your new disk, you still can't use it for storage right away. To use a new disk for storage, you first need to initialize it. This process prepares the disk for Windows by writing a disk signature and selecting a partition style (MBR or GPT).

For this task, we recommend using AOMEI Partition Assistant. This professional software provides a user-friendly interface and various features for managing and optimizing disk partitions on Windows 11, 10, 8.1, 8, and 7.

Here's how to activate a new hard drive on Windows 10 using this tool:

Step 1: Install and launch AOMEI Partition Assistant. Right-click on the raw disk that you want to initialize and choose Initialize Disk

Disk Initialize

Step 2: In the pop up window, select an option for your disk and click OK to continue.

Choose Disk Style

Step 3: Click Apply to start the process, and wait for it to complete.

Apply Initialize

Stage 3. Create a Partition on the Disk

After creating a partition table, you’ll need to set up a file system before the new disk can be used for storage. AOMEI Partition Assistant makes this easy by letting you create new partitions or format existing partitions with just a few clicks. Unlike Windows Disk Management, it offers more file system options and greater flexibility.

 Here's how to create a new partition on a disk:

Step 1: Right-click the unallocated space and select Create Partition in the right panel. 

Create Partition Unallocated Space

Step 2: In the pop-up window, click Advanced to specify the information for the new partition, including partition size, partition label, drive letter, file system, and partition type. You can also specify the partition size by dragging both edges. Then, click OK to continue.

Edit New Partition

Step 3: Click Apply and Proceed to start the operation.

Apply Create Partition

If you want to quickly partition a disk, use the Quick Partition function to create multiple partitions at once.

Pro Tips: Clone Your Old Disk to the New One

If you're replacing an old hard drive, especially the system drive, reinstalling Windows and all your applications from scratch can take a lot of time. Fortunately, AOMEI Partition Assistant includes a powerful disk cloning feature that lets you copy everything from your old disk to the new one quickly and safely.

Follow these steps to clone your old disk to the new one:

Step 1: Right-click the disk you want to clone and select Clone Disk. If you only want to clone the OS, use the Migrate OS feature.

Clone Disk

Step 2: Choose the old disk that you need to clone as the source disk and click Next.

Select Source Disk

Step 3: Select the new disk as the source disk, and then click Next.

Select Destination Disk

Step 4: After all is set, you can click the Confirm button to continue.

If you're cloning to an SSD, you can check the 4K alignment option to help improve its read and write speed.

You can click the Settings button to adjust the partition size on the destination disk. But if you choose Sector by Sector Clone, you won’t be able to change it.

Edit Disk

Step 5: Click Apply and Proceed to start the process.
