EFI disk labeling / understand the parition table / sectors not continue
Hi all,
I have a EFI disk and it is use in zfs pool.
It mentioned that there are total of (a)1172107117 + (b)16384 = 1172123501 sectors (c)
Partition 8 = 1172107151 to 1172123534 = 16384 sectors which match (b)
Partition 0 = 256 to 1172107150 = 1172106895 sectors which dont match (a)
Addup the sectors in the 2 partitions
which is <= to the total sectors (1172123501) (c)
If i say partition 0 = first sector 0 to 1172107150 which addup to 1172107151 sectors which is then even more then 1172107117 (a)
How it all adds-up ?
Where are all the missing or extra sectors ?
