Eu tenho um arquivo de imagem de disco no meu disco rígido externo. Eu tentei extrair o arquivo do arquivo mac.dmg usando 7z x mac.dmg e é isso que eu recebi:
Processing archive: mac.dmg
Extracting 0.MBR
Extracting 1.Type EE
Everything is Ok
Files: 2
Size: 250059350016
Compressed: 201276607141
Eu fiz file 1.Type EE e recebi:
1.Type EE: GPT data structure (nonstandard: at LBA 0), version 1.0, GUID: 66741e19-807b-4f4f-a1e4-652d7892adf3, disk size: 488397168 sectors (sector size unknown)
Eu não sei o que fazer.
Adendo:
Depois de discutir o problema com @the_Seppi, aqui estou:
Usando: gdisk -l ubun.img recebo:
Caution: invalid main GPT header, but valid backup; regenerating main header
from backup!
Caution! After loading partitions, the CRC doesn't check out!
Warning! Main partition table CRC mismatch! Loaded backup partition table
instead of main partition table!
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged
****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.

Fazendo isso:
%código%
%código%
sudo apt-get install hfsprogs
Eu entendo isso:
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Então, tentando mkdir \mnt\backup , eu entendi:

Pelo que você pode ver, esse arquivo é realmente uma imagem de disco.
Você precisa convertê-lo em um arquivo img usando dmg2img ( sudo apt-get install dmg2img ), então você pode montar o arquivo img resultante em um dispositivo de loop para navegar pelo seu conteúdo:
mount -o loop example.img /home/you/dir
