mounting usb-stick manually

Solved.

when i try to mount a stick i get this:

Code:

# mount /dev/sdb1 /media/disk

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

Code:

# dmesg | tail

[ 2852.066714] scsi 2:0:0:0: Direct-Access    USB_DISK USB_DISK        1.00 PQ: 0 ANSI: 0

[ 2882.202526] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

[ 2882.240087] FAT: codepage cp437 not found

so: do i a) miss a tool to mount it (like msdos-tools or such) or b) did i miss something when compiling the kernel.

thank you

try

Code:

mount -t vfat /dev/sdb1 /media/disk

thanks, the result is the same.
apt-cache search vfat only gave me the msdostools, and they are installed. as said: i compiled the kernel on my own, without knowing exactly what i did (just for fun)...oh my. i wouldnt know how to get to know if that is the problem.

What filesystem is on the drive?
If it is ntfs, you need to compile it in the kernel

Code:

mount -t ntfs /dev/sdb1 /media/disk

Code:

mount -t ntfs /dev/sdb1 /media/disk

that is difficult to answer for me. fdisk -l gives me this:
/dev/sdb1 1 1994 1004287+ 6 FAT16
so, as far i understand, it aint a ntfs-system. or better: mounting it with -t ntfs tells me so.
on my other installation i may mount it with a simple

Quote:

mount /dev/sdb1 /media/disk

but its a different kernel.
thanks

Here's another option to try:

Code:

mount -t auto /dev/sdb1 /media

This works for me with a vfat formatted usb flash drive.

ok, i booted into a lenny-backorts kernel and had no problems mounting the same stick.
how may i figure out whats missing in the other kernel? thanks

i yet gotta try the mount -a way trooper has mentioned, but, to be honest, i aint got much hope it will work (well: i will see).

greetings

Make sure you have the module

Quote:

nls_cp437

installed

Code:

modprobe -l | grep nls_cp437

awsome !
so: youre right, the mentioned module is installed in the backports-kernel (which mounts the stick) and aint installed on mine (under /lib/modules/2.6.30-mt1/kernel/fs/nls i cant find it)

just to be sure: i got to re-configure the kernel and run the compilation again, correct?
thanks a lot

SOLVED ( i dont know how to edit the first post, sorry)
repo wrote:

Code:

nls_cp437

which was correct. i ran the make menuconfig and the compilation again and added it under:
filesystems -> native language support -> codepage 437 (UnitedStates, Canada).
Not that i would understand it, but im happy it works again.
