Partition Recovery Course - GPT Test
Check what you can get from GPT header
checksum of table of entries
filesystem type
expected disk size
physical sector size
pointer to the backup copy of GPT
Why do the disks with GPT have MBR as well?
to provide additional performance
to provide compatibility with old partitioning software
two partitioning schemes are better than one
to provide additional reliability in case of failure
Each entry in the GPT table of entries describes one partition
true
false
There is a backup GPT header
false
true
Partition GUID stored in GPT entry is very important for partition recovery
true
false
What is the size of GPT entry?
usually 128 bytes but this is not obligatory
256 bytes
128 bytes
Check what a GPT partition entry contains
partition name in UTF-8 encoding
partition GUID
first sector of the partition
filesystem GUID
partition name in UTF-16 encoding
last sector of the partition
partition size in bytes
How many GPT header copies are stored?
4
2
3
Check where you should not to forget to look for GPT if you deal with an old GPT disk where
one sector back from the 128 GB boundary
one sector back from the 2 TB boundary
ten sectors forward from the 128 GB boundary
in 1024th sector
Check the main GPT structures
MBR
