But Acronis True Image not cloning after restart. Why Acronis WD clone failed? Is it possible to fix it? If not, is there any alternative WD disk cloning software?”

Don't worry about too much and I'll show you how to fix it in this article. Keep reading below to learn the situations and solutions to Acronis True Image WD edition clone not working.

3 Situations to Acronis True Image WD edition will not clone

1. Acronis True Image not cloning after restart. When you clone disk using Acronis True Image within Windows, you will be asked to restart computer. However, your computer may not reboot to recovery enviroment.

Explain: In this case, you probably enable the secure boot in BIOS, but it does not allow this boot path as part of the cloning process. Secure boot is a security measure built into a system's BIOS to prevent untrustworthy firmware from running. To clone disk, you should turn off secure boot at first.

2. Acronis not recognizing WD HD/SSD. Acronis True Image WD edition does not support exFAT file system, so Acronis won’t recognize it and you cannot use hard drive formatted as ExFAT as target drive. And most of the modern digital drive is formatted with exFAT. So, you need to format exFAT to FAT32 or NTFS or turn to a professsional disk cloning software like AOMEI Backupper Professional.

Explain: The most possible cause is that the drive does not have a valid MBR or a third party software is blocking the access to hard disk drives.

3. Acronis True Image WD edition installation restricted - this product edition requires at least one Western Digital drive to be installed in your system. This situation is very similar to the second one, but this problem is related to USB cable connected to WD disk.

Acronis Not Enough Free Space To Install Windows

This articles provides multiple solutions to fix 'There is not enough free space on partition or disk' error which may happen to C partition, system upgrade or USB drives. It is annoying operations can't be completed on account that disk or partition is running out of space. If you are confused by this low disk space issue, continue reading and find solutions to free up disk space and extend partition. This low disk space issue is discussed in four cases and you can click following links to reach corresponding content.

Case 1: There is not enough space available on the disk(s) to complete this operation
Case 2: Not enough free space on USB flash drive
Case 3: There is not enough free space on partition (c :)

Case 1: There is not enough space available on the disk(s) to complete this operation

You may encounter this issue when creating, shrinking or extending volume or converting basic disk to dynamic in Disk Management. For example, when you shrink a volume, it only allows a little space to shrink even though there is a lot of free space in this volume. Sometimes, you may receive the error 'There is not enough space available on the disk(s) to complete this operation'.

Disk Management is a Windows built-in tool used to manage hard drive and partitions on hard drive. Disk Management is able to initialize disks, create or format volumes with FAT, FAT32 and NTFS file system. Besides, it has ability to perform disk related tasks without restarting system such as extend and shrink partitions. Useful as it is, Disk Management can't fulfill all operations users demand and gives errors.

What are the reasons for this error?

Reasons behind this not enough space issue can be many, and this section list the most common ones:

  • The limitation of extended partition and disk management tool.
  • After disk management is open, other partition management software changed disk size. Disk Management doesn't refresh the actual partition status, thus it fails to show the real volume size.
  • You are shrinking a volume beyond the point where some unmovable files are located.
  • The volume you want to shrink is indeed running out of space and it does not have enough free space to complete required operations.

Solutions to fix this problem

Solution 1: Rescan disks

This approach aims to update disk information so that Disk Management shows what disk and partition's status really is. Partitions and disks will be reloaded and Disk Management will be able to recalculate free space for disk resizing. It's easy to rescan disk in Computer Management: click 'Action' menu and select option 'Rescan Disks'. If you still get the low disk space error, you should try steps in solution 2.

Solution 2: Resize partition using free partition manager

If Disk Management fails to complete operation because of not enough free space, you can use third-part disk management alternative to continue the operation. In this case, the most recommended tool is free partition manager DiskGenius which provide basic & advanced disk and partition management functions, including resize / extend / shrink/ split partition without disturbing current data. Thus you can resolve the low disk space issue with this free tool easily. Download and install Eassos free partition manager on your PC and you can follow steps below to resize any partition.


Step 1 Run DiskGenius and locate the partition you want to shrink or resize. Select the partition and right-click it to choose 'Resize Partition' option, as follows:

Step 2 Set partition size you want to move and click Start button. DiskGenius provides two ways to define volume size: you can move mouse to the either edge the partition and drag mouse after it turns to a double arrow; another way is entering exact size in following column. Resized space can be set to keep unallocated, move to other partition or create a new partition.

Step 3 Wait for the resizing process to complete and then close software.

Case 2: Not enough free space on USB flash drive

An error may appear when you attempt to transfer data to a USB drive whose free space is not enough, and the error message appears on a box called 'Error Copying File or Folder', saying there is not enough free disk space. Delete one or more files to free disk space, and then try again. To free space on this drive by deleting old or unnecessary files, click Disk Cleanup. In addition to that, another error may occur if you copy a file larger than 4GB to a USB drive. In that case, the USB flash drive also reports there is not enough free disk space even though there is plenty of free space.

Causes of this error

Many flash drives are sold at a very cheap price, many of which are faulty or have a fake size. For example, a flash drive is tagged as 32GB which is actually only 4GB. The unscrupulous manufacturers play tricks to make the 4GB flash drive display as 32GB in Windows. However, it is not able to store that much data. When you copy large amount data to it, it will report free space is not enough.

The cause of this problem is that many USB flash drives are formatted as FAT32 files system which has a limitation of 4GB on per file size. Thus you can't storage a file larger than 4GB to the disk no matter how much free space it contains. Thus, you should check available free disk space and file system type on the USB flash drive. If file is too large for the destination file system, you can fix it by converting FAT32 to exFAT or NTFS file system which does not have single file size limit.

Fix not enough free space on USB flash drive

Solution 1: Format USB flash drive into exFAT file system

Windows offers formatting function, but it can't format USB flash drive into exFAT if the capacity is too large. If that is the case, you can use the disk management alternative – DiskGenius to complete the formatting. In consideration of data safety, take a full backup for files on the flash drive such as copy all data to your computer before proceeding following steps.

Step 1 Insert the USB flash drive to computer and launch DiskGenius. In the main interface, you can see all disks attached to computer and partitions they contain.

Step 2Does spectrum offer free installation. Select the partition on USB flash drive that reports error and click 'Format' button from tool bar. Then you can see a Format window popping up.

Step 3 Select 'exFAT' in the drop down list for Files System and click 'Format' button.

Solution 2: Convert FAT32 to NTFS with Command Prompt

Command line is able to convert FAT32 to NTFS file system without erasing file on the disk and there is the guide:

Step 1 Insert USB drive to computer and wait for a while so that Windows can recognize it. Open File Explorer to view and remember its drive letter.

Step 2 Open Command Prompt. Click Start button and enter cmd in the searching box. Right click 'cmd.exe' from searching list and select Run as administrator. Click Yes or give permission if you are asked by UAC.

Step 3 Type chkdsk G: /f and press Enter. Note: G is the drive letter of the USB flash drive and it can be other letter on your computer.

Step 4 Type convert G: /FS:NTFS and press Enter. When the process is done, go to File Explorer to check whether file system is properly converted.

If your flash drive has been converted to exFAT or NTFS and still gets the error, then you should check disk's correct capacity or contact manufacturer to fix it.

Case 3: There is not enough free space on partition (c:)

Symptoms of this issue

It's like to get this error when you try to upgrade Windows but failed, such as from Vista to Windows 7, from Server 2008 to 2008 R2, from Server 2003 to 2008 R2, from 2008 R2 to Server 2012. The error message could be 'The following issues are preventing Windows from upgrade, complete each tack, and then restart the upgrade to continue. There is not enough space on partition (C:). A total space size megabytes (MB) of free disk space is required. Try Disk Cleanup, or moving files to an external location such as CD, DVD, or external hard drive, and then restart the installation.'

Another scenario of this error happens when operating system is nearly full. When you open Windows Explorer you can see the system partition shows red and Windows gives an alert on taskbar to ask you to free up disk space. The error message could be 'Low Disk Space You are running out of disk space on system (C:). To free space on this drive by deleting old or unnecessary files, click here…'

People who do not know how much space Windows 10 takes upgrade current system to Windows 10 and gets error message: Windows needs more space. We need 5.00 GB of space on the drive C: for the upgrade. To make space available for upgrade, remove any files and apps that you no longer need or try one of these options: Use Disk Cleanup to free up space. Choose another drive or attach an external drive with 12.0 GB available. Sometimes, you may get error codes such as 0x80070070-0x50011, 0x80070070-0x50012, or 0x80070070-0x60000.
