Hi all,
I wrote a code segment to get the information of a SATA's partition:
//SATA devices have MediaId = 0.
if (SataBlockIo != NULL && SataBlockIo->Media->MediaId == 0) {
if (((HARDDRIVE_DEVICE_PATH*)TmpPath)->MBRType ==
MBR_TYPE_EFI_PARTITION_TABLE_HEADER &&
((HARDDRIVE_DEVICE_PATH*)TmpPath)->MBRType ==
SIGNATURE_TYPE_GUID) {
INFO ("PartitionEndLBA: %lx\n",
((HARDDRIVE_DEVICE_PATH*)TmpPath)->PartitionSize +
((HARDDRIVE_DEVICE_PATH*)TmpPath)->PartitionStart - 1);
INFO ("LastBlock: %lx\n", SataBlockIo->Media->LastBlock);
}
}
But LastBlock (SataBlockIo->Media->LastBlock) is not equal to End LBA
(PartitionSize + PartitionStart - 1).
I want to read/write the "last block" of a partition. Should I use
LastBlock or End LBA?
Thanks,
Hien
