How to Fix the Error ‘The specified disk is not convertible’?

Fix Error The specified disk is not convertible

Converting the MBR to GPT is a good option as it can not only allow you to use a hard disk of more than 2TB but can also speed up system boot time. The error ‘The specified disk is not convertible’ implies that the disk that the MBR disk is not convertible to GPT. Since this error is related to MBR and GPT partitioning, it is important to understand what these terms indicate and what are they used for.

What is the Difference Between MBR and GPT?

A partition is a small logical division on a hard disk. A partition table is a table that contains details about the different partitions on the disk. There are 2 types of partition tables; namely MBR and GPT. MBR is an old method of partitioning that is still in use even today. Some disadvantages of MBR are that it supports hard disk sizes of only 2 TB and it doesn’t allow more than 4 partitions on the disk.

GPT, on the other hand, is a new method of partitioning that allows you to create an almost infinite number of partitions on the disk (but Windows limits it to 128) and one partition can have about 256 TB space. Another advantage of using GPT style is that it stores multiple copies of boot and partitioning data. So even if this data is corrupted, GPT is capable of recovering it easily, which is not possible with MBR.

How do I Fix Specified Disk is Not Convertible Error?

Due to the advantages of GPT’s offer, you may need to convert your MBR disks to GPT. And in order to convert MBR to GPT, users often make use of the Disk Management tool. Although it works in most cases, it may fail in some cases and result in errors like ‘The specified disk is not convertible’. This is often due to not clearing the disk before beginning the MBR to GPT conversion or some errors during the conversion process.

You will find detailed instructions below on how to overcome this error and convert the disk from MBR to GPT using a command-line tool called DiskPart.

To enter Command Prompt, just type ‘cmd’ in the search box and right-click on Command Prompt icon. Then click ‘Run as Administrator’

When the command prompt opens, follow the instructions below:

  • Type ‘diskpart’ and hit Enter
  • Type ‘list disk’ and hit Enter
  • In the list of disks, note down the disk # of the disk you want to convert
  • Type ‘select disk #’ (where # is the disk # you want to convert to GPT) and hit Enter
  • Type ‘clean’ and hit Enter
  • Then type ‘convert mbr’ and hit Enter

Now the process of converting MBR to GPT will begin. Once the process completes, your newly created GPT disk will be ready. However, you need to be aware that the Clean command will erase all the partitions and their data on the drive. Hence, you need to take a backup of the drive before converting it.

In case you have lost your data after running the Clean command or have missed out on backing up some important data before the conversion, it is very difficult to retrieve the lost data. However, with an automated solution, such as Remo Recover you can get back lost data from the deleted partitions effectively. The Deep Scan algorithm of the software can access you lost data by scanning each sector of the drive. Download and try the software for free now.


The solution presented in the above article will certainly help you fix the “The specified disk is not convertible” error. However, if you’ve encountered data loss after converting MBR to GPT and if no backup is available, then there are data recovery tools such as Remo Recover that can recover the lost data for you.

If you’ve encountered data loss after a disk related operation and no backup is available, then there are data recovery tools such as Remo Recover that can recover the lost data for you. This software is capable of recovering all kinds of files like documents in various formats, images, videos and such. This tool can also be used to recover files lost due to MBR corruption. In such cases, if an entire partition has to be recovered, the tool does so very diligently by making sure the original structure of files and folders along with file names are maintained. You can also use this tool to recover data from GPT protective partition.
