Broken Windows flashdrive after sudo cp

Question

I copied a PDF file on Ubuntu to my Windows-formatted flashdrive with

sudo cp file.pdf /mnt/sdb4/

(I am not sure if /mnt/sdb4/ was the path though).

Now I can't access the drive neither from Windows nor from Linux(it doesn't appear in My Computer). I don't want to format it as there were some important files on it. How can I fix it?

Insert your USB to the system and then run lsblk command. Finally post it's output on your question. — Avinash Raj, May 05 '14 at 10:09
@enedil Why you remove the output of lsblk command from the OP's question? — Avinash Raj, May 05 '14 at 10:35
It was Windows-formatted FAT(probably 32). I think that copying this file broken the filesystem in some way. — Alan, May 05 '14 at 10:42
post the output of sudo mount /dev/sdb1 /media/usb command in your question along with the input. — Avinash Raj, May 05 '14 at 10:45
command: sudo mount/dev/sdb1 /media/usb, output: mount: you must specify the filesystem type — Alan, May 05 '14 at 10:46
it's not sudo mount/dev/sdb1 /media/usb, it's sudo mount /dev/sdb1 /media/usb — Avinash Raj, May 05 '14 at 10:47
@Avinash Raj when I started editing, the output wasn't present. — enedil, May 05 '14 at 13:00

Run the below commands on terminal(ctrl+Alt+T) to mount your USB drive manually,

sudo mkdir /media/usb
sudo mount /dev/sdb1 /media/usb

Now the files in your USB would be found on /media/usb directory.

When I do sudo mount/dev/sdb1 /media/usb I get mount: you must specify the filesystem type. After adding -t vfat I get mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error – Alan May 05 '14 at 10:31
post the output of sudo blkid command in your question. – Avinash Raj May 05 '14 at 10:34
if you want to mount an exfat partition then follow this http://askubuntu.com/a/451376/202806 – Avinash Raj May 05 '14 at 10:39
