New version created by Scorpiuss[edit]

I've created a new version of the GPT page. The fundamentals are all there. Could use a chart of the things represented at each bit position. Microsoft's got a nice one on the external link indicated (which, by the way, is a great source).

EFI System partition GUID contradiction[edit]

The GUID for an EFISys partition under the Partition Entries section is different than the one in the list of GUIDs. On the MS page linked at the bottom, the one given in the Partition Entries section is given.


Error in GPT disk layout figure[edit]

I have been trying to understand the GPT disk layout. From reading the UEFI spec and other pages, my impression is that the secondary (alternate) GPT header is located in the last addressable block on the disk. However, the figure (GUID Partition Table Scheme) is not consistent. The caption says that -1 is the last addressable block, but following the same graphical logic as used at the top of the figure the figure indicates that the secondary GPT header starts at -2 and ends at -1, i.e., it indicates that that the secondary GPT header is located at the second addressable block from the end, which should be wrong.

Am I right in this? Who has made the figure and how can we modify it?
