Basically, you can deem that there is no limitation on partition number of GPT disk. That means a capacity exceed 2.2TB cannot be addressed by MBR partitioning scheme. DiskGenius - Complete partition manager to manage GPT & MBR disk and make best of disk space. In short: MBR can have four primary partitions; GPT can have 128. For MBR disk, it can only work with the disk up to 2TB and supports up to four primary partitions. This information includes where partitions start and begin, so your operating system knows which sectors belong to each partition and which partition is bootable. Here Are Solutions. Then just wait for the conversion to complete and close the program. Partition table defines and stores partition information, locating certain disk space on the beginning area. You have to partition a disk drive before you can use it. Partition should be formatted to NTFS or FAT files system before storing data. The standard user will likely have no desire to do this, especially since SSDs are better suited to current operating systems like Windows 10. Then you can select partition number, file system format, volume label, each partition's size, 4K alignment.
