Hoje eu me vi com um pendrive de alta capacidade, com centenas de arquivos, e totalmente irreconhecível no meu sistema GNU/Linux.
Procurando por uma solução, eu me deparei com o utilitário testdisk, que funcionou maravilhosamente bem.
O aplicativo faz parte do repositório Debian/Ubuntu/LinuxMint. Para instalar digite, como root, o seguinte comando:
# apt-get install testdisk
Uma vez que o software tenha sido instalado, basta executar, como root, o comando abaixo:
# testdisk
Aparecerá então a tela inicial do programa, com informações e um menu inicial de ações:
TestDisk 6.13, Data Recovery Utility, November 2011 Christophe GRENIER <grenier@cgsecurity.org> http://www.cgsecurity.org 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: >[ 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 <ENTER>.

TestDisk is free software, and
comes with ABSOLUTELY NO WARRANTY.
Select a media (use Arrow keys, then press Enter):
>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.

It's very rare for a drive to be 'Non-partitioned'.
Selecionamos então o tipo de partição, que já vem assinalada por padrão. Teclamos <ENTER> para prosseguir.
TestDisk 6.13, Data Recovery Utility, November 2011 Christophe GRENIER <grenier@cgsecurity.org> http://www.cgsecurity.org Disk /dev/sdb - 32 GB / 29 GiB - CHS 30532 64 32 >[ Analyse ] Analyse current partition structure and search for lost partitions [ Advanced ] Filesystem Utils [ Geometry ] Change disk geometry [ Options ] Modify options [ MBR Code ] Write TestDisk MBR code to first sector [ Delete ] Delete all data in the partition table [ Quit ] Return to disk selection Note: Correct disk geometry is required for a successful recovery. 'Analyse' process may give some warnings if it thinks the logical geometry is mismatched.
A situação é de um pendrive ilegível, seleciono então a primeira opção, Analyse.

Respondo então Yes:
