When trying to mount:

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

Then add to dmesg:

[148400.299406] FAT-fs (sdc): invalid media value (0x7c)
[148400.299417] FAT-fs (sdc): Can't find a valid FAT filesystem

Is the flash drive completely dead or still recoverable?

Answer 1

At one time, flashboot.ru/index.php?name=iflash , this site helped me. there, by vid and pid, you can see a utility that helped people. though as a rule they are all under win

Answer 2

> sdc: unknown partition table
clearly said. hence two options.
1. you have something uploaded there that cannot be recognized as a valid PT or FS.
2. it didn’t count, because the controller or memory died, but in this case, dmesg would contain mention of block device reading errors, I don’t see them, so most likely p.1
We treat (actions from root):
$ dd if=/ dev/zero of=/dev/sdc bs=1M count=10
make sure that /dev/sdc will be a flash drive, otherwise it will be funny
$ fdisk /dev/sdc
create partition: n,p,1
change type: t,b (b is FAT32)
save and exit: w,q
create file system
$ mkfs.vfat -F 32 -n ASX43847 /dev/sdc1
$ sync
take out the flash drive, insert, look

Answer 3

There was such a problem, it was cured with the help of the HP Format Tool, try it, suddenly you will succeed

Answer 4

Are you sure that there were 4GB on the flash drive before? Maybe it's a Chinese fake ?

Answer 5

As an option computerinfo.ru/umenshilsya-obem-fleshki Summary cmd->diskpart->LIST diskpart->SELECT dist=№ (SELECT disk=5)->CLEAN cmd->diskmgmt.msc->we are looking for a flash drive->Create a simple volume->Next...
