GPTPartitionen

GPTPartitionen refers to partitions created on a storage device using the GUID Partition Table (GPT) scheme. GPT is a modern standard for the layout of partition tables on a physical storage device, such as a hard disk drive or solid-state drive. It is part of the UEFI (Unified Extensible Firmware Interface) specification, which is gradually replacing the older BIOS firmware interface.

GPT was designed to overcome some of the limitations of the older Master Boot Record (MBR) partitioning scheme. One significant advantage is its ability to support a much larger number of partitions than MBR, which is typically limited to four primary partitions or a combination of primary and extended partitions. GPT can support up to 128 partitions by default on many operating systems, and this number can often be increased.

Another key feature of GPT is its robustness. It stores partition table information at both the beginning and the end of the disk, providing redundancy. This helps in data recovery if the primary partition table at the beginning of the disk becomes corrupted. GPT also uses globally unique identifiers (GUIDs) to identify each partition, reducing the chance of conflicts.

While MBR is still supported for backward compatibility, GPT is the preferred partitioning scheme for modern systems, especially those using UEFI firmware and large capacity drives exceeding 2 terabytes. Operating systems like Windows, macOS, and Linux all support GPT.
