  # apt-get install testdisk


Uma vez que o software tenha sido instalado, basta executar, como&nbsp;root, o comando abaixo:

  TestDisk is free data recovery software designed to help recover lost
  partitions and/or make non-booting disks bootable again when these symptoms
  are caused by faulty software, certain types of viruses or human error.
  It can also be used to repair some filesystem errors.
  
  Information gathered during TestDisk use can be recorded for later
  review. If you choose to create the text file, testdisk.log , it
  will contain TestDisk options, technical information and various
  outputs; including any folder/file names TestDisk was used to find and
  list onscreen.
  
  Use arrow keys to select, then press Enter key:
  &gt;[ Create ] Create a new log file
   [ Append ] Append information to log file
   [ No Log ] Don't record anything


Vamos deixar na primeira opção (Create). Para prosseguir, tecle .

    TestDisk is free software, and
  comes with ABSOLUTELY NO WARRANTY.
  
  Select a media (use Arrow keys, then press Enter):
  &gt;Disk /dev/sda - 500 GB / 465 GiB - ST500DM002-1BD142
   Disk /dev/sdb - 32 GB / 29 GiB - SanDisk Cruzer Blade
  
  Note: Disk capacity must be correctly detected for a successful recovery.
  If a disk listed above has incorrect size, check HD jumper settings, BIOS
  detection, and install the latest OS patches and disk drivers.
  ecover files
  or partitions off dead flash drives, usually fried by Windows, or any hard drive
  or removable media 


Nesta tela temos os dispositivos para os quais poderemos efetuar ações de recuperação. Neste caso, a minha opção é por realizar uma verificação do pendrive, a segunda opção disponível.

  Disk /dev/sdb - 32 GB / 29 GiB - SanDisk Cruzer Blade
  
  Please select the partition table type, press Enter when done.
  &gt;[Intel  ] Intel/PC partition
   [EFI GPT] EFI GPT partition map (Mac i386, some x86_64...)
   [Humax  ] Humax partition table
   [Mac    ] Apple partition map
   [None   ] Non partitioned media
   [Sun    ] Sun Solaris partition
   [XBox   ] XBox partition
   [Return ] Return to disk selection
  
  Note: Do NOT select 'None' for media with only a single partition. It's very
  rare for a drive to be 'Non-partitioned'.


Selecionamos então o tipo de partição, que já vem assinalada por padrão. Teclamos  para prosseguir.
