![]() ![]() The starting address of a partition should be divided by physical block size without a remainder. Remember to align all partitions based on physical drive block size to get the best performance out of your disk drive. This table can then be extended further as needed. In comparison, the GPT scheme by default has a table with 128 entries for partitions. In MBR, you can choose to create either of the two options: option 1 - four (4) primary partitions, option 2 - three (3) primary partitions and one (1) extended partition with MBR table in a single drive, which can be further divided into logical partitions. Only EFI systems can be booted from GPT partitions.Īnother limitation of the MBR scheme is the number of partitions that you can create in it. ![]() Note: Windows systems cannot boot from GPT partitions if the system is being booted with legacy BIOS code. When GPT is implemented in a machine together with MBR, the HDD must be initialized using the GPT scheme if its capacity is over 2TB if capacity is lower, either MBR or GPT can be used. We are seeing this transition as GPT co-exists with MBR to provide some backward compatibility to older systems. The GPT scheme is in the process of superseding MBR in newer computers. ![]() Current computing needs however are finding it limiting as its maximum addressable storage space in a disk is only 2TB. The MBR is the most widely used partitioning scheme in x86 machines. ![]() Though there are different kinds available, the two partition schemes usually used in x86-compatible systems are the Master Boot Record (MBR) and GUID Partition Table (GPT). To partition a hard disk drive (HDD) is to divide a single physical disk into multiple logical storage units so that a different file system can be implemented in each partition.
