Clonezilla Destination Disk Is Too Small (2023)

Clonezilla error: Destination disk is too small

Clonezilla is an open-source disk cloning & imaging tool whichhelps users create exact copies of hard drives or partitions fordata migrationor backup purpose. However, many users have run into this destination disk too small issue during cloning hard drives of different sizes.

Why does this problem occur and how to fix it? Keep reading to get details.

2 scenarios for“Clonezilla destination disk is too small”

When will you receive "Clonezilla target disk is too small" error message? There are usually 2 cases:

• Clonezilla restore destination disk is too small. If you have backed up a large drive and want to restore it to a smaller disk, you will receiveClonezilla destination disk is too small error.

  Many users want tomigrate OS form hard drive to an SSD, which is generally smaller than HDD at the same price. Clonezilla backups the original size of file system. When Clonezilla tries to restore the original file system onto a smaller disk, it cannot write beyond the destination disk boundary.

• Clonezilla clone destination disk is too small.The clone function of Clonezilla uses the same way to clone data, so you may get the same error when you clone a larger hard drive to a smaller SSD.

Now, you may have this question: is it possible to let Clonezilla restore or clone alarge disk to smaller one?

Fix "destination disk too small"via Clonezilla -icd mode

According to the Clonezilla Official, Clonezilla is not supposed to clone from a larger disk to a smaller one. However, many users have such needs to clone or restore larger disk to smaller one when they want to replace HDD with SSD.

To satisfy users needs, Clonezilla provides an advanced –icds mode, which canlet Clonezilla ignore disk size while cloning or restoring.That’s to say, if you use this mode, Clonezilla will not check the destination disk size before creating partition table.

To restore image to smaller drive using Clonezilla, see steps below:

1.Download, install and start Clonezilla. Then, launch this software, choose language > handing keymaps “Don’t touch keymap” > “Start_Clonezilla Start Clonezilla” and hit “Ok” after each option.

2.Then, mount clonezilla image directory. Just select “device-image work with disks or partitions using images” > “local_dev Use local device” and hit “Ok” in turn. After that, mount a local device as /home/partimag and then choose the directory of local disk, hit “Ok” subsequently.

3.Select export mode and restore with image. Choose “Expert Export mode: Choose your own options” > “restoredisk Restore_an_image_to_local_disk” > select the image file to restore > press space key to select “-icds” option > keep the default values and select “-p true Do nothing when clone finishs”, and click “Ok” one by one. After that, just wait until all the process ends.

✍Note: Clonezilla uses "-icds" to ignore disk size, but sometimes the problem may not be the size of the disk, but the size of the partitions. If the sum of the partition sizes are larger than the destination drive, Clonezilla will fail. To make it work successfully, you need to choose "Resize partitional table proportionally" as well, which can shrink the partitions before running Clonezilla with "-icds".

With this method, some users have successfully performed Clonezilla cloning to smaller destination disk. But it's not 100% effective.

If you find it complicated or still fail cloning or restoring,you can shrink the source drive via disk management, or, try an much easier alternative.

Once and for all: Restore or clone to smaller destination disk easily

If Clonezilla says disk is too small after trying all above workarounds, you can consider using effective disk imaging and cloning software software like AOMEI Backupper Standard.

How to restore larger disk to smaller disk

Preparations:

• Install the new HDD or SSD to your computer.If there's only one drive slot, you may need a SATA to USB cable or clousure to connect it.

• If any important data exists on the target disk, make a backup first to prevent it from being overwritten during the recovery process.

Step 1.Use AOMEI Backupper to create a system backupof the source hard drive. You can choose Disk Backupfor a entire disk copy, or System Backupfor only system-related partitions.

Step 2.Click Restoreand Select Taskto find the backup image.

Step 3. Select the system backup image and click Next.

Step 4.Choose Restore this system backupand click Next.

Step 5. Preview the operation and clickStart Restore.

📑Tips:The “Universal Restore” feature allows you to restore system image to computer with dissimilar hardware. It is available in advanced editions.

Also available: Clone to a smaller destination disk

You can also use AOMEI Backupper to directly clone a hard drive to a smaller drive without restoration. It includes Disk Clone, System Clone and Partition Clone features to suit your different needs.

Note that if you want to transfer Windows to another driveas well, you need to use AOMEI Backupper Professional. Download the free trial to demonstrate the cloning functions.

Step 1. Launch AOMEI Backuppe, clickClone->Disk Cloneto start the cloning process.

Step 2.Choose the source hard drive and destination drive subsequently, and then clickNext.

Step 3.Choose the smaller destinationdisk and clickNext.

Step 4. Review the operation summary andclickStart Cloneto execute the cloning.

📑Tips:

✏It's suggested to tickSSDAlignmentwhilecloning hard drive to SSD, because it canoptimize the performance of SSD disk and makeyour computerrun faster after cloning.

✏Do notcheckSector by sector clonebecause this feature is to clone all sectors on larger drive, and it will fail to clone bigger drive to smaller drive due to insufficient disk space.

✏Edit Partitionsis used to avoid unallocated space after cloning hard drive to larger drive. You can "Copy without resizing partitions,"Manually adjust partition size" or "Add unused space to all partitions" easily.

Step 5. (Optional) Replace larger drive with the smaller disk and try to boot from it. If itdoesn't automatically boot from the cloned drive, you need to change boot priority to it in BIOS and try again.
