MiniTool Partition Wizard cannot extend the specified partition. It shows not enough free space, but there is much free space.

There are 3 possible causes for this issue: 1. There is non-NTFS or non-FAT partition(s) between the partition you want to extend and the partition or unallocated space you want to take free space from. If yes, please take a screenshot to show us disk layout in MiniTool Partition Wizard so that we can give you some advise. 2. you are extending a partition on an MBR disk by taking free space outside 2TB, because on an MBR disk you can only use 2TB of space. In this case, converting the disk from MBR to GPT could fix it. 3. You are extending a partition by taking free space on another disk. Currently, MiniTool Partition Wizard only supports extending partition by taking free space on the same hard disk.

Received the error "The last operation will create an overlapping partition" when resizing partition.

Could you please use the Align Partition function to align partitions that will be operated during the process of resizing, and then resize partition again?

Extend Partition or Move/Resize Partition function is grayed out.

Firstly, please check whether the partition you want to resize is highlighted. If not, functions under the Partition tab will be grayed out. Secondly, please check whether you are resizing a dynamic volume. If yes, all functions under the Partition tab are grayed out, and you need to click the Dynamic Disk tab. Thirdly, please check whether your partition is encrypted. When a partition is encrypted, our program will show it as Other. In this case, you need to decrypt the partition, and then resize it. At last, please check file system of the partition. Currently, Partition Wizard can only resize NTFS and FAT 12/16/32 partition.

Shrunk D but still can't extend C to unallocated space.

Partition C: and partition D: should be on the same hard disk. If you have the problem when C: and D: are on the same disk, most probably you used the Move/Resize Partition function to extend, but the unallocated space is not adjacent to C:. In this case, please use the Exend Partition to extend C: directly. You can also send us a screenshot to show disk layout in MiniTool Partition Wizard so that we can give you some instructions.

The program found lost partition, but after I clicked the Apply button, the disk becomes unallocated again.

This problem appears largely because partition size and disk size are not consistent. In this case, you need to use the Linux bootable version of MiniTool Partition Wizard to recover partition. Could you please send your order ID or registered email address to [email protected]? Once the order is confirmed, we will send you the Linux version.

The program found overlapped partitions and I cannot tick them.

It seems new partitions were created after partition loss, and 2 or more partitions are overlaped. In this case, could you please double click each partition to explore contents, and then try checking needed partition? However, if you are unable to check all needed partitions, the best way is to recover data with MiniTool Power Data Recovery. If you already purchased MiniTool Partition Wizard, you can pay difference to get the data recovery software.

Recovered partition isn't showing up in Windows Explore or File Explorer.

Could you please check whether the partition has a drive letter? If it doesn’t have, please assign it one with the Change Drive Letter feature.

Still can't open recovered partition, and Windows asks to format.

It seems this partition has file system errors. Could you please use the Move/Resize Partition feature to shrink the partition a little, several GB for example. During the process of resizing, our program could fix slight file system errors. If this method doesn't work, please use the Check File System feature of MiniTool Partition Wizard to do some repair. However, if the partition is showing up as Other or Unformatted in MiniTool Partition Wizard, you need to recover data with MiniTool Power Data Recovery. You can pay difference to get our data recovery software.

Why the Apply button is grayed out after I run Partition Recovery.

Most probably all your partitions are existing. Only when the program finds deleted partitions, the Apply button is available. Under this situation, please take a screenshot to show us disk layout in MiniTool Partition Wizard so that we can give you some advise.

At least one of the existing partitions will be deleted. Are you sure that you want to continue?

When doing partition recovery, users need to choose all needed partitions, both existing and lost/deleted ones, because unchecked partitions will be deleted.

Get the error message "The selected Partition Layout is invalid" when doing partition recovery.

It might be because the structure of your disk is corrupted. In this case, you need to send us a screenshot of the Choose Searched Partitions window so that we could give you some advice. However, if you can't recover partition even with our suggestions, you may need to use our data recovery software.

Get the error message "The specified disk is dynamic disk" when doing partition recovery.

Please convert dynamic disk to basic disk and then do partition recovery again.

When doing partition recovery, I can view data but have no option to recover them or can't open them.

The Explorer feature of Partition Wizard doesn't detect the integrality of file system deeply and it just offers a preview effect. Just follow instructions to recover the partition, and then you should be able to access it in Windows Explorer or File Explorer.

Windows won't boot after partition recovery.

Most probably you just selected the lost/deleted partitions. In the Choose Searched Partitions window, you need to select all needed partitions, both existing and lost/deleted ones. Currently, please send us your order ID or registered email address to [email protected], and we can reset your activation. Then, you can install and register the program on a working computer, create a bootable disk, and boot the unbootable computer from the created bootable disk to recover your partitions. Please choose all needed partitions this time.

Invalid configure file.

Could you please send your order ID or registered email address to [email protected] for further assistance?

The process got stuck for a very long time. Can I cancel it?

If the Cancel button is available, you can cancel the process without worrying about data loss. However, if it is grayed out, please wait the program to complete the operation. You can also send a screenshot to [email protected] Our technicians can review it and give you some instructions.

Can't change cluster size. It reported the disk required defragmenting. Defragmented the disk and it still failed.

If the program gives the same error after you defragmented the disk, probably you need to defrag MFT. This tool is more powerful than Windows built-in Defragmenter:
https://www.ccleaner.com/defraggler. You can also try the bootable version of MiniTool Partition Wizard.

How much time does changing cluster size require?

It is affected by many factors but mainly depends on how many files should be moved. Let's just see a simple example:
The above represents old clusters, while below represents new clusters.
If file A is saved in old cluster 5, it is not located at the starting position of new cluster. For successful reading, our program will move it to a free new cluster. If file B is saved in old cluster 8, 9, 10, and 11, it just uses a new cluster, and our program will keep file B in this location. In reality, the changing cluster size process is much more complicated, and our program will move or keep data to fit new cluster size.

During the process of changing cluster size, can i use the volume?

For data security, the volume will be locked during changing cluster size. So, you can't use it during the process.

Can i use your program to change cluster size of my volume so that i can extend it?

In this situation,we suggest directly extending it. During the extending process, our software will change the cluster size automatically. And with the added free space, the program should complete the increase faster.

Received a warning when changing cluster size. Please see the attached image.

You received this error message because you are operating boot partition. Changing cluster size of boot partition will cause system unbootable, we don't suggest performing this operation.

Can't choose desired partition to merge.

Cause 1: partitions you want to merge are not neighboring. In this case, you can't merge them. Instead, you can take free space from one partition to extend the other using the Extend Partition feature.
Cause 2: one or both partitions are not NTFS partitions. The Merge Partition feature can only combine NTFS partitions. If they are FAT32 partitions, please convert them to NTFS using the Convert FAT32 to NTFS feature, which will not affect data, and then merge again. If they are Ext or other types of partitions, you can't merge them.

I want to clone old disk to SSD, but the program said the SSD is too small while it has enough space to save contents on the old disk, and the program incorrectly thinks the C-drive partition is full.

It seems your partition is encrypted, please open Windows Disk Management to check whether C: is encrypted. If yes, you need to decrypt it at first.

Get the "The specified disk is too small" error when copying disk.

The target drive should have enough space to hold all files saved on the source disk.

Received the error "Destination device must be an unallocated space".

In this case, please delete a useless partition or shrink a large partition to create an unallocated space, and then copy partition again.

Get the "The specified disk is too small" error when migrating OS only. The target disk has enough space to hold Windows. Why?

The Migrate OS feature will copy all system required partitions to the target disk, along with all files saved in these partitions, incluidng Windows, installed programs, settings, personal data, etc. You can transfer some files out from the OS partition, and then migrate system again.

Get the error "Since a different sector size on the source disk and destination disk, MiniTool Partition wizard cannot continue" when copying disk/partition or migrating OS.

You failed to migrate OS/copy disk/copy partition because the target drive and the source drive have different sector size. To be specific, one drive uses 512B sector, while the other uses 4K sector. In this case, MiniTool Partition Wizard can't help you, and we suggest using other disks if you have.

The target disk is unbootable.

Please try the following methods:
1. Please connect the target drive via SATA or connect it internally to the motherboard and see whether it is bootable.
2. Try to use a Windows installation media to repair the target drive.
3. Try booting the computer from the Windows installation media, open CMD and running the following 3 commands to do some repair:
• bootrec /fixboot
• bootrec /fixmbr
• bootrec /rebuildbcd
However, if all the methods fail to fix the issue, please boot the computer from the source disk, and take a screenshot to show us the disk layout of both disks in MiniTool Partition Wizard.

Get the error "Partition Wizard detected your disk configuration has changed" when cloning hard disk or migrating OS.

Please disconnect all USB storage devices, then restart computer, connect the target USB disk to the computer, and run MiniTool Partition Wizard to copy disk again.

What's the difference between the Copy Disk and Migrate OS feature?

The Copy Disk feature will copy all partitions along with files to the target disk while Migrate OS feature offers 2 options. One is to copy disk, and the other is to migrate OS only. Migrating OS only just copies system required partitions.

Received the error "Failed to read or write disk" when copying disk/partition or migrating OS.

It seems there are bad sectors on your hard disk. Could you please run chkdsk /r /f on your source disk in CMD, and then copy or migrate again? If it doesn't work, could you please try bootable version of MiniTool Partition Wizard?

Windows won't boot from cloned partition.

That is because copying Windows OS partition will not fix and update boot information. Instead, we suggest using Migrate OS to SSD/HD or Copy Disk feature to clone or transfer Windows.

Can't find the Rebuild MBR function or this function is grayed out.

Firstly, please check whether it is a GPT disk. GPT disk doesn’t have MBR, so there is no Rebuild MBR feature for GPT disks. Secondly, please check whehter it is a dynamic disk. If yes, you need to convert it to basic disk, and then rebuild MBR. At last, to rebuild MBR, you need to highlight the disk. If you highlight a partition, you'll not see the Rebuild MBR feature or it is grayed out.

The check File System function is grayed out.

Firstly, please confirm the partition you want to check is highlighted. Then, please confirm it has a drive letter. If it doesn’t have a letter, please assign it one and try again. At last, please confirm this partition is formatted with FAT or NTFS. Our program doesn't support checking EXT and HFS+ partition.

All partitions got lost after I applied the conversion.

Could you please send the log file of MiniTool Partition Wizard to [email protected], which is located at the installation directory of the program and called log.txt.

Windows won't boot after you converted the system disk to GPT.

Firstly, could you please check whether UEFI boot is enabled. If it is already enabled, could you please take a photo with your phone to show us the exact boot error?

Get the error message "MiniTool Partition Wizard cannot convert this GPT disk to MBR. (Too many primary partitions)

You received this error message because an MBR disk can only hold 4 primary partitions at most. To fix this issue, you have 2 choices:
1. delete extra partitions after important data is backed up. For example, if there are 5 partitions on the GPT disk, you can delete a small partition, and convert again; if there are 6 partitions, you need to delete 2 partitions.
2. Shrink partitions with the Move/Resize Partition feature if you do not want to delete partition. For example, if there are 5 partitions on the disk, please shrink the last partition to create a 1GB or smaller unallocated space before the partition, and then use the same method to shrink the fourth partition; if there are 6 partitions, you need to shrink the last 3 partition. After that, you should be able to convert the disk to MBR.

MiniTool Partition Wizard cannot convert this GPT disk to MBR. (partition layout exceed 2TB limit)

You received this error message because MBR disk has a 2TB limit. In this case, we suggest keeping GPT if you want to use all space. But if you need to convert GPT to MBR due to some reason, please delete or shrink the last partition and confirm existing partitions just use 2TB or less capacity.

My external drive has a single partition. I want to split it and create a new partition for backup.

For your case, you can shrink the current partition to get an unallocated space and then create new partition on the unallocated space.

When resizing my usb drive to create new partition, I received the error: MiniTool Partition Wizard cannot create a new partition on this removable disk. If you like to create several partitions on this removable disk, you need to delete all the partitions first.

You received this error most probably because your USB drive doesn't have partition table. Can you please select the first partition of the drive, choose Move/Resize Partition feature, shorten the partition handle to create a small unallocated space before this partition, and apply the change. Then, try creating the second partition.

Receive "No free MBR slot" error when creating partition.

The error occurs because there are 4 primary partitions or 3 primary partitions plus one extended partition already. To fix this issue, you need to convert one of the primary partitions adjacent to the unallocated space to logical partition. For steps to convert partition, please see Set Partition as Logical.

I deleted/format a partition on my SD card. The program reported successfully, but in fact the partition is still existing.

Probably this drive has physical issues. Please try using Surface Test feature of MiniTool Partition Wizard to scan it and see whether there are bad sectors on it.

I reduced the size of the C drive and added 3 new partitions which are supposed to be D E F.
I could assign E and F with no problem but cannot assign the D. It does not appear in the option of letters to choose.

Most probably letter D is assigned by your CD-ROM or other devices. Could you please check it in Windows Disk Management? If yes, you can change CD-ROM to another drive letter and assign D: to your new partition.

Assigned a letter for the partition and clicked apply. The program says it is done but the drive letter disappears.

You can try the following method: select the problem drive, then select Change Partition Type ID feature, next change partition type ID to 0x07, and assign drive letter again.

I'm unable to assign letter for the second partition on my USB flash drive. Why?

Windows only recognizes the firstly created partition of removable device. That's why you can't assign letter for the second partition.

I booted computer from MiniTool bootable version, my C drive is showing up F: . I then changed it to C, but after rebooting, it back to F:.

Bootable MiniTool Partition Wizard is running in Win PE while the Windows edition is running in normal Windows OS. Under different systems, drive letters are a little different, but both are correct.

I highlighted partition C and want to assign D: to it, but under Partition tab, the Change Drive letter function is grayed out.

We do not allow users to change drive letter for OS partition, because it may affect system.

I want to convert my FAT32 partition to NTFS, but the convert FAT to NTFS function is not visible.

Probably this partition is hidden. In this situation, you need to unhide it at first.

I want to extend a dynamic volume, but if i click on menu - partition, all menus are grayed out and i can´t click on extend.

To extend a dynamic volume, you need to choose the Dynamic Disk menu. Actually, after you highlight the volume you want to extend, you can see all available functions on the left panel. Please choose Move/Resize Volume feature to extend your volume.

I want to take the unallocated space to extend a dynamic volume, but when i go to Resize/Move function, i can't choose the unallocated space.

MiniTool Partition Wizard supports extending a dynamic volume, but you need to move the unallocated space to be after the volume you want to extend.

How to extend striped or mirrored volume?

Firstly, there should have unallocated space on both dynamic disks, and the unallocated space needs to be adjacent to the volume you want to extend. Then, you can only use same space on both disks to extend the volume.

I can't extend my C volume by using free space on another dynamic disk.

On dynamic disk, you can extend a volume by taking free psace on another dynamic disk, and this volume will automatically convert to spanned volume, but volume C is an exception. Windows doesn’t allow it to use space on other dynamic disks.

Please see the attached image. I was trying to convert my dynamic disk to basic, but received error "failed to convert the specified dynamic disk".

You received this error message because an MBR diks can only hold 4 primary partitions at most. To fix this issue, you have 2 choices:
1. delete extra partitions after important data is backed up. For example, if there are 5 partitions the dynamic disk, you can delete a small partition, and convert again; if there are 6 partitions, you need to delete 2 partitions.
2. Shrink partitions with the Move/Resize Partition feature if you do not want to delete partition. For exampple, if there are 5 partitions on the disk, please shrink the last partition to create a 1GB or smaller unallocated space before the partition, and then use the same method to shrink the fourth partition; if there are 6 partitions, you need to shrink the last 3 partition. After that, you should be able to convert the dynamic disk to basic disk.

MiniTool Partition Wizard can't convert the specified dynamic disk to basic disk.

Please read Fixed: MiniTool Partition Wizard Cannot Convert the Specified Dynamic Disk to Basic to get the details.

How to convert my mirrored dynamic drive to basic?

Firstly, please break mirrored volume (not remove mirror) in Windows Disk Management, which doesn't affect data. Then, please retry conversion using MiniTool Partition Wizard.

Got "Failed to convert the specified dynamic disk" error when converting dynamic disk to basic disk in MiniTool Partition Wizard. The disk shows "dynamic invalid" in Windows Disk Management and "Bad Disk" in MiniTool Partition Wizard.

It seems this dynamic disk is from another system. If the disk wasn't a part of striped volume, spanned volume, or RAID volume before, please go to Windows Disk Management, right click the dynamic disk, and choose Reactivate Disk. In general, this should make your disk workable again. However, if you receive an error message, please choose Convert to Basic Disk instead, which will delete all partitions, but you can recover all deleted partitions using MiniTool Partition Wizard. We have tested this method for multiple times, and all worked.

When I copy my volume to another drive, it reported that this program detected file system error.

The error message means there are file system errors on your drive, please use Check File System to repair original volume and try again.

The cluster size of the specified partition is too small to use by FAT32 file system. You need to change the cluster size to 16 sector(s) first.

Please high light this partition, choose Change Cluster Size feature, set cluster size to 16 sectors, then execute Apply. After that, please retry converting this NTFS partition to FAT32.

During converting my NTFS partition to FAT, I received an error: The specified partition contains a file larger than 4GB.

You got this error message because FAT 32 partition doesn't support files larger than 4GB. Could you please backup the large files to another drive, then delete them and try again?

Can't convert a 4TB NTFS Partition to FAT32.The error says can't convert the specifiedpartition to FAT file system. It's too large.

The maximum size for an FAT32 partition in Windows is 2TB, so you can't convert a 4TB drive from NTFS to FAT32. If files saved on this drive are less than 2TB, you can shrink the partition to 2TB, and then convert the 2TB NTFS partition to FAT32.

I changed type ID of one little partition, and now it is showing up as "Storage Space Protective Partition" in Windows Disk Management, but MiniTool Partition Wizard can't detect the disk.

The disk is not showing in MiniTool Partition Wizard most probably because you set this partition as Storage Spaces Partition. If you didn't save important data on it, would you mind using Diskpart to delete this partition and try again?
Note: Please choose the correct partition to delete.

Can MiniTool Partition Wizard flag and fix bad sectors?

MiniTool Partition Wizard Surface Test feature can only test whether there are bad sectors but can't flag and fix bad sectors.

Error code 2

Probably there are illegal value in the partition. In this case, could you please use the "Check File System" function to do some repair? If this method doesn't work, you need to recover data using MiniTool Power Data Recovery at first, and then recreate the partition.

Error code: 3

The error code shows there are bad sectors on the drive. Could you please use Surface Test feature of MiniTool Partition Wizard or CHKDSK.exe to see whether it has bad sectors? If there is bad sector, you can try running chkdsk /r in CMD and then try again.

Error code 4, error code 40

Sometimes, when you are trying to manage disk partitions, you receive the following error messages after hitting the Apply button:
"Failed to execute the following command:
Error Code: 4
Disk I/O error."
"Failed to execute the following command:
Error Code: 40
NTFS file system error. Please use "Check File System" function to fix it first."
How did this happen? During the process of installing MiniTool Partition Wizard, there is a remote possibility that the related device drivers which are responsible for invoking system information are installed inappropriately.
Now you can do the following operations to remove such errors:
Step 1: Run "regedit", find the folders "pwdrvio" & "pwdspio" under "Computer > HKEY_LOCAL-MACHINE > SYSTEM > CurrentControlSet > Services" and then delete them.
Step 2: Restart your computer.
Step 3: Reboot MiniTool Partition Wizard. During this step, the related device drivers will be reinstalled and work normally. At this time, you can successfully execute the operations you did before.
