Partition Recovery Course - LDM Recovery Test
What you need to get from VBLK blocks describing a volume when recovering LDM?
this object ID
partition start LBA
parent volume ID
disk object ID
What is in the LDM database?
only VBLK blocks and a transaction log
several blocks of different types and a transaction log
only VBLK blocks
Check what LDM metadata contains
EFI PART signature
PRIVHEAD
partition GUID
VBLK blocks
Check what you need to get from VBLK blocks describing a component when recovering LDM
parent volume ID
disk object ID
partition start LBA
this object ID
Check why PRIVHEAD is that important
it allows to determine RAID configuration
it allows to bind LDM components
it allows to identify disks
it contains the base sector from which all addresses throughout LDM metadata are measured
Location of LDM database can be found in PRIVHEAD
true
false
Check what PRIVHEAD stores
partition size
block size for RAID5
PRIVHEAD signature
physical disk GUID
Logical Disk Start
LDM metadata always occupies exactly 1 sector
true
false
When recovering LDM manually, you need VBLK blocks to
determine Logical Disk Start
determine the location of MBR
determine filesystem type
link various LDM objects
Disk identification in LDM recovery is done using
LDM database
GPT or MBR data
PRIVHEAD
