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.
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.
