Partition Recovery Course - LDM Recovery Test

LDM metadata can occupy several megabytes

true
false

In what units values stored inside VBLK blocks are measured?

in bytes
in clusters
in physical sectors
in 512-byte sectors

VBLK blocks link to each other by object identifiers

false
true

In what units offsets in PIVHEAD are measured?

in physical sectors
in clusters
in bytes
in 512-byte sectors

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

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

When recovering LDM manually, you need VBLK blocks to

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

Check where PRIVHEAD copies are located on a disk with MBR

at the end of the disk
at the beginning of the disk
anywhere but always before LDM metadata

How a partition start is calculated?

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

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

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