Gostaria de montar um dispositivo de armazenamento em massa ATMEL (USB) para acessar os dados que foram gravados no dispositivo médico que estava usando.
Abaixo estão os comandos que eu executei e as saídas correspondentes.

A partir dessa saída, determinei que o disco estava em / dev / sda, mas não tenho certeza do significado das linhas de pacote máximas inválidas.
Quando tentei montar:
raspberrypi:~$ sudo mount /dev/sda /media/usb-drive/
mount: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try dmesg | tail or so.
Então corri o dmesg:
raspberrypi:~$ dmesg | tail
[1034.801104] F2FS-fs (sda): Magic Mismatch, valid(0xf2f52010) - read(0xffffffff)
[1034.801108] F2FS-fs (sda): Can't find valid F2FS filesystem in 2th superblock
[1108.115588] F2FS-fs (sda): Magic Mismatch, valid(0xf2f52010) - read(0xffffffff)
[1108.115606] F2FS-fs (sda): Can't find valid F2FS filesystem in 1th superblock
Em seguida, uma série de comandos foi executada, conforme sugerido por outros posts de solução de problemas.
raspberrypi:~$ sudo parted /dev/sda -l
Error: /dev/sda: unrecognised disk label
Model: ATMEL Mass Storage MSD (scsi)
Disk /dev/sda: 373MB
Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags:
Não tenho certeza do que isso significa por rótulo de disco não reconhecido.
raspberrypi:~$ sudo file -sL /dev/sda
/dev/sda: ISO-8859 text, with very long lines, with no line terminators
Isso significa que posso simplesmente copiar o disco inteiro com o dd como um arquivo e depois analisá-lo com um script python?
raspberrypi:~$ sudo fdisk /dev/sda -l
Disk /dev/sda: 355.9 MiB, 373161984 bytes, 728832 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Este último parece promissor, mas não sabe quais devem ser os próximos passos na minha exploração.
