Pertanyaan

Pembaca SuperUser, Clay Nichols ingin tahu apakah partisi GPT memiliki kemungkinan kecil untuk korup dibandingkan dengan yang berbasis MBR:

I know that GPT (GUID Partition Table) partitioning has some benefits over MBR (Master Boot Record), including support for:

  • More partitions (128)
  • Hard drives larger than 2TB

Are there any other benefits like less potential for corruption or are you just playing whack-a-mole where GPT can also become corrupted in the same way as MBR? The two hard drive failures I have experienced were due to corrupted MBRs.

Apakah partisi GPT lebih kecil kemungkinannya untuk korup dibandingkan dengan yang berbasis MBR?

Jawabannya

Penyumbang super User mtak memiliki jawabannya untuk kami:

According to the Wikipedia article on GUID Partition Tables, there is redundancy built into the GPT partition scheme. The GPT header is written at the beginning as well as at the end of the disk (see graphic below). In addition, the partition table header also contains a CRC32 checksum for itself and for the partition table.

The redundancy is not available in the MBR partition scheme, which only occupies the first 512 bytes of a disk. The extra redundancy would allow for more resilience against corruption. The CRC32 checksum allows the system to detect which of the two headers is the correct, uncorrupted one if a problem arises so that it can be used to repair the other one.
