Partition Recovery Course - LDM Recovery Test

Check what LDM metadata contains

partition GUID
PRIVHEAD
VBLK blocks
EFI PART signature

Check what you need to get from VBLK blocks describing a partition when recovering LDM

this object ID
partition start LBA
disk object ID
parent component ID

When recovering LDM manually, you need VBLK blocks to

determine filesystem type
link various LDM objects
determine the location of MBR
determine Logical Disk Start

VBLK blocks link to each other by object identifiers

true
false

Check what you need to get from VBLK blocks describing a disk when recovering LDM

parent component ID
this object ID
Logical Disk Start
disk GUID

How a partition start is calculated?

(Start LBA) + (Logical Disk Start)
(Start LBA) + (Logical Disk Start)*(LBAs per physical sector)
512*(Start LBA) + (Logical Disk Start)
(Start LBA) – (Logical Disk Start)
512*(Start LBA) – (Logical Disk Start)

Based on what a component is linked with a volume?

component is not linked with volume
this object ID stored in component object matches this object ID stored in volume object
parent volume ID stored in component object matches this object ID stored in volume object

Based on what a partition is linked with a component?

parent component ID stored in partition object matches parent volume ID stored in component object
parent component ID stored in partition object matches this object ID stored in component object
disk object ID stored in partition object matches parent volume ID stored in component object
