Subject: [PATCH 23/89] gpt: permit "mklabel gpt" on a 67-sector device
|
|
|
|
* libparted/labels/gpt.c (gpt_alloc): Correct checks in order to
|
|
allow creation of a GPT partition table on a 67-sector device.
|
|
The computation of the "data_end" sector number was one too low.
|
|
Whereas there are two sectors at the beginning of the disk (pMBR
|
|
and the GPT header sector), there is only one at the end: the
|
|
backup GPT header. That (67) is the size of the smallest GPT
|
|
partition table, allowing for *no* partition table sectors.
