Partition Recovery Course - LDM Recovery Test
Disk identification in LDM recovery is done using
GPT or MBR data
LDM database
PRIVHEAD
Check what you need to get from VBLK blocks describing a disk when recovering LDM
Logical Disk Start
disk GUID
this object ID
parent component ID
In what units values stored inside VBLK blocks are measured?
in clusters
in 512-byte sectors
in physical sectors
in bytes
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 object ID
stored in partition object matches
disk GUID
stored in PRIVHEAD
disk GUID
stored in disk object matches
parent component ID
stored in partition 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
disk object 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
LDM metadata always occupies exactly 1 sector
false
true
Check what you need to get from VBLK blocks describing a partition when recovering LDM
disk object ID
parent component ID
this object ID
partition start LBA
Check what PRIVHEAD stores
block size for RAID5
Logical Disk Start
partition size
PRIVHEAD signature
physical disk GUID
When recovering LDM manually, you need VBLK blocks to
determine the location of MBR
determine filesystem type
determine Logical Disk Start
link various LDM objects
LDM metadata on a disk with GPT is stored in a special partition
true
false
