Clone HDD to SSD With Macrium Reflect Complete Step by Step Guide

A new SSD is the single biggest speed upgrade an old PC can get — and cloning means you keep your Windows, programs, files and settings exactly as they are. This is the complete, careful walkthrough of cloning an HDD to an SSD with Macrium Reflect, in the right order, with the checks that stop the classic mistakes.

Reinstalling Windows from scratch after an SSD upgrade takes a full day of drivers, programs and settings. Cloning skips all of it: Macrium Reflect copies your existing system to the new SSD, partition by partition, and the PC boots from the SSD as if nothing changed — except everything is suddenly fast. This guide follows the same happy path as the video: a healthy old drive, a planned upgrade, no drama. Do the steps in order. The two places people go wrong are skipping the small system partitions and testing the first boot with both drives still connected — both are covered below, and both are free to avoid.

Before You Start — the Three Honest Checks

Cloning is a copy, and a copy is only as good as what it starts from. Run these three checks first; they take five minutes and decide whether this job is a calm upgrade or something else entirely.

  1. The old drive must be healthy. This guide is for a planned upgrade on a working drive. If the HDD is clicking, vanishing, or already throwing read errors, stop — a failing drive needs a rescue-first approach, not a happy-path clone, because every extra minute of reading shortens its life.
  2. The SSD must hold your used space. Add up what is actually used on the partitions you are cloning — not the size of the old disk. A 1 TB HDD with 300 GB used clones happily onto a 500 GB SSD. A 1 TB HDD with 700 GB used does not fit a 500 GB SSD until you free or move some data.
  3. Back up anything irreplaceable separately. A clone normally touches only the destination disk, but cables get pulled and wrong disks get clicked. Photos and documents that exist nowhere else deserve a copy on an external drive or in the cloud before you begin.

Connect the SSD and Open the Clone Wizard

On a desktop, the cleanest setup is to fit the SSD in its final home now — a spare SATA data cable plus a SATA power connector — and clone with the HDD still in place. On a laptop with one drive slot, connect the SSD through a USB to SATA adapter or a USB enclosure for the clone, and swap it inside afterwards. Either way, Windows should see the new disk in Disk Management before you start; if it does not, fix that first, because Reflect cannot clone to a disk the PC cannot see. The full adapter walkthrough is in the companion guides in this set.

  1. Open Macrium Reflect and find your old HDD in the disk list
  2. Under that disk, click Clone this disk
  3. In the wizard, click Select a disk to clone to and choose the new SSD — check the model name and size twice, because the destination gets wiped completely
  4. Tick Copy selected partitions with all partitions selected, or drag each partition down onto the SSD

Size the Partitions and Start the Clone

If the SSD is the same size or bigger, Reflect can copy partitions as they are. If the SSD is smaller, this is where you shrink the big Windows partition to fit — select it on the destination, open Cloned Partition Properties, and drag the size down, leaving some free space rather than filling the SSD to the last megabyte. Reflect only needs room for the used data. One setting worth leaving alone: partition alignment. Reflect aligns partitions correctly for SSDs automatically during a clone — you do not need to hunt for an alignment option.

  1. Review the destination layout — small system partitions first, then Windows, then recovery
  2. Click Next through the summary pages; skip the schedule page — a one-time clone does not need a schedule
  3. Click Finish, then OK to run the clone now
  4. Let it finish without using the PC heavily. Reflect copies only the used sectors of supported file systems, so the clone is usually much faster than the raw disk size suggests

First Boot — Test the SSD Alone

This is the step that proves the clone, and the order matters. Shut the PC down, disconnect the old HDD completely (data cable is enough on a desktop; on a laptop the SSD is now the only drive anyway), and start the PC. It should boot from the SSD into your familiar desktop — noticeably faster. Disconnecting the old drive is not superstition: with two bootable copies attached, some PCs quietly boot the old one, and you can spend an hour wondering why nothing feels faster. The dedicated guide in this set covers the boot-order fix if your PC ever does boot the wrong drive later. Test your main programs, open a few files, and restart once more before you call it done.

Finish the Job — TRIM Check and the Old Drive

Two five-minute finishing tasks. First, confirm Windows is treating the new drive as an SSD by running fsutil behavior query DisableDeleteNotify in a terminal — a result of DisableDeleteNotify = 0 means TRIM is enabled, which is what you want. Second, decide the old HDD's future deliberately: keep it disconnected for about a week as your instant fallback, then reconnect it, wipe its old Windows partitions, and use the whole disk as a plain data drive. Both finishing tasks have their own step-by-step guides in this set — follow them rather than improvising, especially the formatting order, because formatting the wrong disk is the one disaster this whole process is designed to avoid.

🔴 The destination disk is erased completely. Before you click Finish, read the destination model name and size one more time. Reflect will overwrite everything on the disk you selected as the clone target — if your backup drive is connected and you picked it by mistake, its contents are gone. When in doubt, disconnect every USB drive except the one you are cloning to.

❓ Frequently Asked Questions

Will cloning delete anything on my old HDD?

No. Cloning reads the source disk and writes only to the destination. Your old HDD stays exactly as it was, which is why it works as a fallback afterwards. The disk that gets erased is the destination SSD — anything already on it is overwritten.

How long does an HDD to SSD clone take?

It depends on how much data is actually used and on the connection. Reflect copies only used sectors, so a half-empty drive clones far faster than its full size suggests. A typical home upgrade over SATA finishes in tens of minutes; a USB adapter is slower than an internal SATA connection.

Is Macrium Reflect free for cloning?

Not any more, and it is better to know that before you start. Macrium retired the Free edition — the last free version was v8.0 and its security patches ended on 1 January 2024. Today Macrium offers Reflect X as a paid product with a full-featured 30-day free trial, and the trial's cloning works completely, which is enough for a one-time upgrade like this. An old Reflect Free install, if you still have one, also still clones — but it is unsupported now. The edition guide in this set explains all of this in detail.
