我想安装 ATMEL 大容量存储设备 (USB)，以便可以访问记录到我佩戴的医疗设备中的数据。
以下是我运行的命令和相应的输出。

从这个输出我确定磁盘位于 /dev/sda 但我不确定无效的最大数据包行意味着什么。
当我尝试安装时：
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.
所以我运行 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
然后，按照其他故障排除帖子的建议运行了一系列命令。
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:
我不确定无法识别的磁盘标签是什么意思。
raspberrypi:~$ sudo file -sL /dev/sda
/dev/sda: ISO-8859 text, with very long lines, with no line terminators
这是否意味着我可以使用 dd 将整个磁盘复制为一个文件，然后用 python 脚本解析它？
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

最后一个看起来很有希望，但不确定我的探索下一步应该是什么。
