Partition Recovery Course - LDM Recovery Test

Location of LDM database can be found in PRIVHEAD

false
true

When recovering LDM manually, you need VBLK blocks to

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

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

parent component ID
disk GUID
this object ID
Logical Disk Start

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

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

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

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

What you need to get from VBLK blocks describing a volume when recovering LDM?

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

Based on what a partition is linked with a disk?

disk object ID stored in partition object matches this object ID stored in disk object
disk GUID stored in disk object matches parent component ID stored in partition object
disk object ID stored in partition object matches disk GUID stored in PRIVHEAD

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

Based on what a component is linked with a volume?

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

How a partition start is calculated?

512*(Start LBA) + (Logical Disk Start)
(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)
