Unknown fs on usb?
Code:
Error mounting: mount exited with exit code 1: helper failed with:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

This happens when I try to mount a usb-stick, that did work before the update on wheezy.
After updating I typed as root after changing to /etc/apt

Code:
cat sources.list

getting this

Code:
# deb cdrom:[Debian GNU/Linux 7.1.0 _Wheezy_ - Official amd64 NETINST Binary-1 20130615-23:04]/ wheezy main 

deb ftp://ftp.br.debian.org/debian/ wheezy main contrib non-free 
# deb-src ftp://ftp.br.debian.org/debian/ wheezy main contrib non-free 

deb http://security.debian.org/ wheezy/updates main contrib non-free 
# deb-src ftp://ftp.br.debian.org/debian/ wheezy/updates main contrib non-free 

# wheezy-updates, previously known as 'volatile'
deb ftp://ftp.br.debian.org/debian/ wheezy-updates main contrib non-free 
deb ftp://ftp.br.debian.org/debian/ wheezy-proposed-updates contrib non-free main 
# deb-src ftp://ftp.br.debian.org/debian/ wheezy-updates main contrib non-free

When typing the so called help

Code:
syslog - try dmesg | tail

(whith od without the blank before the "try") I am getting the notice, no such command. So may someone has a hint. The usb-stick used to work with ext4. What coud have happend?

Code:
mount /dev/sda1 /home/<my-user-name>/usb_stick -t vfat

does not help either. Glad for any help, thanks in advance.


going ahead trying this

Code:
tail -f /var/log/syslog

after that plugging in the usb-stick the terminal (using as root) tells me tons of tails

Code:

So I see it is ext checking, and now I am looking for clues, because there it says that this is ext3 as fs.
And
Code:
udevinfo -a -p /sys/block/sdh

this command does not help at all :-(
