GPT Disk Supported, MBR Disk limits with conditions

GPT disk OK, MBR disk limitations with 4 primary partitions at most and 2TB max disk capacities.

For a 4TB SSD or HDD, when you initialize it MBR, the disk can be created with partitions 2TB max and unallocated space 2TB. It's not possible to add the unallocated space to the disk partitions no matter C D E G or any drive due to the limits of MBR disk.

Other Information

Sometimes you may notice an error when you use an SSD or hard drive. It may bring you to the 'Extend Volume' option in the Disk Management tool. But why does the extended volume error greyed out in Windows Server 2022 occur?

Let us find the reasons behind the issue as under;

  1. There is no unallocated space on the disk.
  2. You cannot extend the C drive (primary partition) by shrinking the D drive (logical partition) on an MBR disk.
  3. You cannot extend the partition drive fat32 as NTFS is the only supporting file system.
  4. One issue is that the maximum partition size on the MBR disk is 2TB. So, if you initialize a 4TB hard disk, you will see the rest 2TB space left as Unallocated. This left-out space cannot be recreated as a new volume nor extended to any other volume.
  5. You do not have or cannot get any free space behind the partition you want to extend.
  6. Your Windows PC cannot extend FAT partition format.
  7. The maximum capacity of the partition has reached its limit 2TB on the MBR disk. You cannot extend it larger.
  8. You cannot find any direct link between unallocated disk space and extendable volume. (The unallocated space is not at the right side of the drive you want to extend)

The issues mentioned earlier may occur because of limits posed by disk management. So we are offering some tips to use for troubleshooting the issue. These foxes will help you resolve the problem instantly.
