Need to switch to a new disk

Before diving into the process, let's understand why upgrading your hard drive is a wise move. Over time, your old hard drive accumulates fragmented data, bad sectors, and general wear and tear that can lead to decreased performance and potential data loss. By switching to a new drive, you can revitalize your system and ensure a smoother computing experience.

When choosing between an SSD and a traditional HDD, the advantages of SSDs are hard to overlook.

SSDs offer lightning-fast read and write speeds, drastically reducing boot times and application load times. They are also more durable due to their lack of moving parts, making them less susceptible to physical damage. Additionally, SSDs operate silently and consume less power, contributing to a more efficient and quieter system overall.

How to select a suitable new disk

Picking the right replacement drive involves more than just choosing between an SSD and an HDD. You'll need to consider factors such as capacity, form factor, and budget. SSDs come in various sizes, typically ranging from 120GB to 2TB or more. Assess your current storage usage and future needs to determine the appropriate capacity. Keep in mind that the price per gigabyte decreases as the drive's capacity increases.

The form factor is another crucial consideration. Most modern laptops and desktops utilize the 2.5-inch form factor, while M.2 drives are becoming increasingly popular due to their compact size and faster speeds. Ensure your chosen drive is compatible with your system's interface.

Lastly, set a budget for your upgrade. While SSD prices have significantly dropped in recent years, they still tend to be more expensive than HDDs. However, the performance boost and longevity of SSDs often justify the higher cost.

Preparations before making the disk switch

Before you embark on the journey of switching hard drives, certain preparations are essential to ensure a seamless transition. These steps will help safeguard your data and minimize potential hiccups during the process.

1. Backup important files
Backing up your data is non-negotiable. While the chances of data loss during a hard drive switch are relatively low, it's always better to be safe than sorry. Create a comprehensive backup of your crucial files, documents, and important settings. 

2. Organize and clean your files
This is the perfect opportunity to declutter your system. Sort through your files and delete any unnecessary documents, old downloads, and duplicate files. A tidy file structure will not only make the cloning process smoother but also save space on your new drive.

Stage 1. Install new disk

After you get the correct disk for you device, shut your computer down and unplug it.

Step 1. Ground yourself before opening the computer. Improper handling of electronic components can cause damage to the system. You can accomplish this by wearing an anti-static wrist strap while standing on an anti-static mat.

Step 2. If you're using a desktop computer, you'll typically need to twist off the screws on the back of the tower and then slide the side panels away from the unit. Some laptops have special doors on the case that allow you to easily insert and remove hard drives. Other models require you to remove the battery and unscrew various components to access the hard drive. Check with your manufacturer to find the correct method for your computer.

Step 3. If your computer has one more place for another disk, you can directly plug the new disk into it. If not, you may need to use an adaptor to connect the new disk to your PC. If so, you can close your computer case or laptop cover.

Stage 2. Initialize new disk

If it’s a new SSD, you should initialize this SSD first, or it can’t be found on the laptop.

Step 1. In Windows, press the "Windows + R" key, type "diskmgmt.msc" and click OK to launch Disk Management.

Step 2. Find and right-click the disk you want to initialize, and then click "Initialize Disk".

If the disk is listed as Offline, first right-click it and select Online.

In lower left corner of the window, you can click the "Settings" button to adjust the partition size on the destination disk. There are three options for you:

• Clone without resizing partitions: all partitions will be cloned to the target disk as the original partition size. It is available when the target disk is larger than the source disk. If it is smaller, this option will be grayed out.
• Fit partitions to entire disk: all partitions will be cloned to the target disk and take up its full capacity according to the original partition size proportion.
• Edit partitions on this disk: you can change every partition size on the target disk as you need.

After finishing the adjustment, please click "Save".

Notes:

• You can tick "4k alignment" to improve the reading and writing speed of SSD if the selected destination disk is an SSD storage.
• All data on this selected destination disk will be wiped out after you save the operation to physical disk. If there is important data on the destination drive, please make a backup in advance.
• If you clone to a smaller SSD, the first option is grayed out. If you select Sector-by-Sector Clone, it is unable to adjust the size on the destination disk.

Step 5. You can preview the disk cloning operating by viewing the "Pending Operations". To commit the "Pending Operations", please click "Apply" and "Proceed".

Step 6. The cloning process will start and you can check the cloning process.

Further tip: What to do with old hard drives after hard disk upgrading?

Congratulations on successfully upgrading your old disk! Now, let's see what you need to do for your old disk.

If you wish to dispose of or sell old hard drives, the first step is to fully erase all data on the disk. Wiping a hard drive is the process of erasing and overwriting unnecessary data on the disk in order to prevent data recovery. As a result, you cannot simply trash or format your old hard drives; these two processes will not preserve your privacy.

AOMEI Partition Assistant Professional is also a disk wiper. The “Wipe Hard Drive” feature offers you easy operations to overwrite the hard drive. You can select a hard drive that you want to wipe; right-click on it and choose the "Wipe Hard Drive" option. Choose a wiping method to wipe the selected hard drive according to your requirements and click "OK". Click "Apply" in the toolbar to execute the operation.

Also, you can reuse your old disk as your data disk. You just need to delete all partitions.
