Flash disk problem

**cbrands** · 12-22-2004, 10:57 PM

I have a problem with my buildin multicard reader.
when I insert a compact flash card it is not detected
I boot from a Knoppix 3.7 CD
lsmod gives me the following output

Code:

ide-scsi                8816   1

and the output from lsusb is

Code:

Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 002 Device 002: ID 0aec:3050 Neodio Technologies Corp. ND3050 8-in-1 Card Reader
Bus 001 Device 001: ID 0000:0000

So the card reader itself is detected
The command

Code:

ls /mnt

results in

Code:

auto  cdrom  cdrom1  floppy  hd  pts  sda1  sda3  sda5  sda6  sdb  sys  test

My hard drive is sda. I think that sdb is the flash disk so Knoppix knows at least at some level that there it is there.
But when I try

Code:

mount -t msdos /dev/sdb /mnt/sdb

I get

Code:

mount: wrong fs type, bad option, bad superblock on /dev/sdb,
       or too many mounted file systems

I dont know what to try next
Thanks

First, try fdisk -l to check what kind of partitions fdisk can see on your flash drive.

Depending on that you might want to try different filesystem types ( I am not sure if vfat is similar to msdos but I always use it to mount fat32 partitions).

I tried vfat but that didn't help
I will try fdisk -l tonight when I get back home. At least I know that the hardware works as I did manage to get it working with
system rescue cd (http://www.sysresccd.org)

I am thinking that maybe some needed kernel module is not loaded.
Thanks for your reply nick666
