The GUID partition table is what it stands for. Similar to MBR, it controls how and where partitions are created on SSDs and HDDs. GPT saves disc information like partition, sizes, and other crucial data in sector one, exactly like MBR, but it does so using UEFI firmware rather than the BIOS used in MBR. Sector one is set aside for MBR compatibility and sector two is used by GPT in contrast. Let's examine the GPT's features.
Features of GPT
- GPT discs provide a significant increase in storage capacity over MBR. Partitions can be made in multiples by users. The GPT disc system supports up to 128 partitions.
- The GPT disc style makes data recovery simple.
- When compared to MBR's restriction of only allowing the creation of 4 primary partitions, the GPT disc system represents a significant advancement.
- The use of GPT is not restricted to windows OS, It is also prevalent in other OS, such as Apple's Mac.
- To make sure the data is secure. GPT can perform checks. To verify the security of the data, it uses CRC values. If the data is corrupted, it can both identify the corruption and make an attempt to recover the corrupted data from other places on the disc. As a result, GPT is a more dependable option than MBR.
- The protective MBR feature, which is part of GPT, is very intriguing. On the entire drive, this MBR only takes into account one portion. When users attempt to manage GPT in such circumstances using an outdated tool, the tool will read one partition dispersed across the drive. Protective MBR ensures that the old tools do not view the GPT drive as not partitioned and guards against any harm caused by the new MBR to GPT data. The GPT data is protected by the protective MBR so it won't be lost.
