Cannot mount USB drive with "wrong fs type, bad option, bad superblock" error message

Question

    lsblk

And when I try

 mount /dev/sdb /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
       missing codepage or helper program, or other error

With dmesg -tail

How to solve this?

Solution

The USB drive seems to be partitioned. Do not mount the device directly, but the partition /dev/sdb1 instead:

mount /dev/sdb1 /mnt

No,the same as before! mount: wrong fs type, bad option, bad superblock on /dev/sdb1,

[Jens Erat]

You might be missing support for the file system in use. How is the partition formatted? You should be able to get some more information with parted /dev/sdb, then run the p command (p as in "print").

[MikiBelavista]

W95 FAT32 is partition type

[Jens Erat]

Try enfording FAT32 as file system: mount -t msdos /dev/sdb1 /mnt. If this still doesn't work, look at the dmesg output if any error message appears while mounting the partition.

[Jens Erat]

The file system seems broken. If you don't have any important files on that drive, considering reformatting. You might be able to use fsck to repair the file system and/or use some data recovery tools to recover files. If there's anything important on it, make sure to create a full image (for example using dd) before doing any work with the broken file system.

[MikiBelavista]

Thanks a lot. I do not have important files on disk.

Start with sudo file -s /dev/sdb1 to do a low-level query. (man file).

@waltinator /dev/sdb1: data

[John Smith Optional]

@Jean Erat : thanks, adding the -t msdos option did the trick for me

Can you provide details on how to achieve the end state, such as specific terminal commands? Is a total erasure necessary after partitioning? If so, why?

@Damian T You really think the OP will answer on a 6 year old question?

@David The comment was to libertyrogue who posted the answer yesterday, not to OP.
