What is cloning a drive?
Drive cloning is the process of making an exact copy of the contents of one hard drive and putting that replica onto another drive (Disk cloning). It allows you to duplicate everything on the source drive including the operating system, installed programs, settings, documents, and other data.
Cloning copies all the contents over sector-by-sector to create an identical clone of the original drive. The entire drive is replicated bit for bit. This cloning process happens directly from one drive to another without the data passing through a computer’s memory.
Drive cloning is done with special disk cloning software or tools. These facilitate copying the full contents from the original source drive to a new target drive. Common disk cloning tools include Macrium Reflect, Clonezilla, MiniTool Partition Wizard, and EaseUS Todo Backup (EaseUS).
Does drive cloning copy the OS?
Yes, cloning a drive copies everything including the operating system. When you clone a drive, the clone is an exact replica of the original drive containing a bit-for-bit copy of all data and partitions [1]. This means if the source drive has an OS like Windows, macOS or Linux installed, the clone will also have the identical OS installation. Cloning replicates the operating system files, system settings, installed applications, user data and all other contents from the source drive.
Drive cloning is different from a clean OS installation. With cloning, you don’t have to reinstall the OS or applications on the new drive. The clone boots up and functions exactly like the original drive right after the cloning process finishes. Everything is migrated over in the cloning operation.
In summary, cloning a drive provides an exact duplicate including the OS installation. You get a bootable clone that works just like the original drive with no need to reconfigure the OS or reinstall programs [2].
Benefits of cloning vs clean OS install
Cloning an existing drive offers some key benefits compared to doing a clean install of the operating system:
Cloning saves a significant amount of time compared to a clean install. With cloning, you can simply copy all the data, programs, files, and settings from the old drive to the new drive in one step. Clean installing the OS and reinstalling programs and transferring files can take many hours. According to UbackUp[1], cloning an SSD can be done in as little as 10-15 minutes while a clean install can take 3+ hours.
Cloning preserves all your existing programs, files, settings, and configuration. With a clean install, you have to manually reinstall programs, recreate settings, and move files. Cloning eliminates this tedious process. As noted by EaseUS[2], cloning means you don’t have to manually back up data and reinstall the operating system.
Overall, for those short on time or wanting to avoid reconfiguring a new drive from scratch, cloning provides a quicker and easier way to migrate to a new drive compared to a clean OS install.

Potential risks and downsides
While drive cloning can be a convenient way to migrate your data and applications to a new drive, there are some potential risks and downsides to be aware of:
One risk is that cloning may transfer viruses or malware from the old drive to the new one. Any malicious programs hiding in the old drive’s boot sectors, system files, or program files could get copied over. To avoid this, it’s best to scan the original drive for malware before cloning. Some cloning software like EaseUS Todo Backup has built-in antivirus scanning.
Another downside is that the clone may reflect an outdated operating system or outdated drivers. If you’ve been running the old drive for a while without updating the OS, cloning it over duplicates those outdated components. A fresh OS install on the new drive would allow starting clean with the latest updates. You can still migrate data separately after a fresh OS install.
There’s also a small risk of corruption or errors during the cloning process itself. Using a reputable cloning utility like Clonezilla and verifying the integrity of the clone can help avoid issues.
Overall, drive cloning requires care and awareness of the potential risks. With proper precautions, it can be a safe and effective migration method.
When to clone vs clean install
There are pros and cons to both cloning a drive and doing a clean install of an operating system. Cloning can be faster and easier for migrating your data and programs to a new drive, while a clean install ensures no software issues carry over but takes more time to reinstall programs and restore data.
According to EaseUS, you may want to clone your drive when “[you] just want to migrate OS and data to a new hard drive without reinstalling everything”. Cloning copies the entire contents of one drive to another, so you can quickly get a new drive up and running just like your old one.
On the other hand, as noted by Reddit users, “A clean install is always better to clear out all the junk, orphaned files etc that build up over time”. Performing a clean OS install formats the new drive and does a fresh installation, which eliminates any persisting software issues, bloatware, or corrupted files.
In summary, cloning is faster but duplicates everything as-is, while a clean install takes longer but gives you a fresh slate. Choose cloning for quick PC migration, and clean install to clear out issues.
How to clone a drive
There are two main methods for cloning a drive – using a physical drive adapter or cloning software. Physical drive adapters like HDD docking stations allow you to connect the source and destination drives via SATA or USB connections. The advantage of drive adapters is that they don’t require any additional software and make cloning a straightforward copy process.
Cloning software offers more flexibility and options for drive cloning. Popular cloning tools include Macrium Reflect, Clonezilla, EaseUS Todo Backup, and Acronis True Image. With software cloning, you can clone drives over a network connection or clone directly from within your operating system. Software cloning also provides options like file exclusion, compression, encryption, and scheduling.
The general process for drive cloning is:
- Connect the source and destination drives to your computer.
- Open your cloning software and select the source and destination drives.
- Start the cloning process – this will copy all data from the source to destination drive.
- Verify the clone was completed successfully in the software.
- Disconnect the source drive and boot from the cloned destination drive.
It’s important to note that when cloning a drive with your operating system, you may need to reactivate or revalidate your OS license on the cloned drive before using it as your main system drive.
Choosing Cloning Software
When it comes to drive cloning software, there are both paid and free options to consider. Some of the top drive cloning programs include:
Paid options:
- Acronis True Image – Offers advanced cloning and backup features for both HDDs and SSDs. Widely considered one of the best paid options (source).
- Paragon Hard Disk Manager – Provides drive cloning along with many other disk management tools (source).
- O&O DiskImage – User-friendly cloning for Windows systems with support for backups and drive imaging.
Free options:
- Clonezilla – Open source cloning software that supports a wide range of file systems and operating systems.
- AOMEI Backupper – Basic cloning features available in the free version.
- EaseUS Todo Backup – Free cloning and backup software with option to upgrade to advanced paid version.
The main trade-off between paid and free is that paid options often provide more features, better performance optimization, and technical support. However, free tools like Clonezilla offer a solid basic cloning solution.
Cloning HDDs vs SSDs
When cloning a drive, there are some key differences to consider between traditional hard disk drives (HDDs) and solid state drives (SSDs) [1]:
HDDs have moving mechanical parts while SSDs are fully electronic. This means HDDs are typically slower, louder, and more prone to physical failure over time compared to SSDs. However, HDDs currently offer more storage capacity per dollar than SSDs.
The cloning process can take much longer for larger HDDs, while cloning smaller SSDs can be relatively quick. SSDs also have a limited number of write cycles over their lifespan, so excessive drive cloning could potentially shorten the longevity of an SSD.
When cloning HDDs, bad sectors can be copied to the new drive. SSDs do not have bad sectors, but a cloned SSD will still contain any existing performance issues from the old drive.
In general, it is considered better practice to do a clean OS install rather than cloning when migrating your system from an HDD to an SSD. This allows your operating system to fully optimize itself for the improved performance of SSD storage.[2]
However, cloning from HDD to SSD allows you to easily migrate your applications, files, and settings to the new drive. It can serve as a quick short-term solution, but a clean install maximizes the benefits of moving to fast SSD storage.
Troubleshooting cloning issues
Cloning a drive does not always go smoothly. You may encounter errors during the cloning process that prevent it from completing successfully. Here are some tips on troubleshooting common cloning issues:
If the clone fails partway through, restart the process. There may have been a temporary glitch. Check that the source and destination drives are properly connected and restart the clone. However, if it fails at the same spot again, there is likely a bad sector on the source drive that cannot be copied.
Try cloning to a different drive if possible. If the clone fails when cloning to one drive but is successful when cloning to a different drive, then the issue was with the original destination drive. It likely has bad sectors or other corruption preventing the clone.
Check for disk errors on the source and destination drives using the CHKDSK utility in Windows. This scans the drives and attempts to repair logical file system errors or bad sectors. Rerun the clone after repairs.
Update the cloning software and associated drivers. An outdated version may have incompatibilities or bugs causing clone failures. Always use the latest version.
If the cloned drive does not boot, make sure the partitions were properly aligned during cloning. Use a partition alignment tool to check and correct if necessary. The boot files may not be accessible if alignment is off.
In rare cases, you may need to repair the boot sector or reconfigure the bootloader like the MBR for an MBR disk. Utilize the cloning software or other drive tools for this repair.
As a last resort, switch to a disk imaging software instead of a cloning utility. Disk images copy over the data in file format, getting around any sector-by-sector copy errors.
Frequently asked questions
Here are some common questions about cloning drives:
Does cloning copy everything on my drive?
Yes, drive cloning makes an exact copy of the entire contents of your drive, including the operating system, installed programs, settings, files, and folders. The clone is a mirror image of the original drive (IDrive).
Will I have to reactivate Windows after cloning?
Typically no. Since the clone contains an exact copy of your operating system, Windows activation should carry over to the new drive. However, you may need to reactivate if you’re switching major hardware components like the motherboard (Crucial).
Can I clone between different drive types?
Yes, you can clone HDDs to SSDs and vice versa. The cloning process makes a bit-for-bit copy, so the drive types do not need to match. Just make sure the new drive is equal or larger in capacity (PC Mag).
Will cloning fix drive errors or problems?
No, cloning replicates everything on the source drive, including any corruption or errors. It’s better to do a clean OS install on a new drive if the old drive has developed issues over time.
