Show Disk Partition Style is a portable utility designed to make determining a disk's partitioning scheme easy.Not that the navigation process through the control panel is overly complicated but there are several steps you need to go through before you can pull and view the results. Show Disk Partition Style makes it much easier since as soon you run the program it immediately displays whether the disk is MBR or GPT.MBR is the standard partitioning scheme that's been used on hard disks since the PC first came out. It supports 4 primary partitions per hard drive, and a maximum partition size of 2TB. The GPT disk itself can support a volume up to 264 blocks in length. It can also support theoretically unlimited partitions Windows restricts these limits further to 256 TB for a single partition (NTFS limit), and 128 partitions.
