Bad superblock?

I finally got my chip reader working (under sdc) but when I try to mount a chip under a vfat fs type i get this error message:

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

Is there anything software related or should I move this to the hadware section?

Hello!

you aren´t trying to mount the partiton.

Greetings

What do you mean?

You should be using a command like $mount vfat /dev/sdc /mnt Is this what you did?

No. I didn't. I'm now currently using this (in /etc/fstab):
/dev/sdc /mnt/unknown vfat uid=1001,gid=0,users,noatime 1 0
Should I try the vfat /dev/sdc /mnt/usb?

I don't know about card readers but *most* USB storage devices don't work by mounting /dev/sdc. Try /dev/sdc1 or /dev/sdc2, see which works for you.

Nope. scdx (where x is any number): "special device sdcx doesn't exist".

Only sdc is recognized.

scdX is the device for scsi cdroms.

cs-cam mentioned sdcX. Most USB disks behave like a hard disk. Sector 0 contains a partition table.
By default, most USB disks have 1 partition so your best bet is /dev/sdc1

Just to put something different on the table for informational purposes only I have a HFS+ partition on a USB device and I mount it from /dev/sda, not /dev/sda1. Filesystem is obviously handled differently to most others but I thought I'd chuck that in for fun

I have a multi-chip reader. It took me a while to get it working until I realised:

The different slots are allocated to /dev/sda /dev/sdb /dev/sdc etc

I had to plug in the memory card into the reader before I plugged the reader into the USB port.

Ahh sorry a typo. it's not scd it's sdc the only port that doesn't say: special device X doesn't exist or no medium found. I have a chip reader that is connected to my motherboard not a usb port.: Pengy:

Oh, and I read that some flash drives/cards are treated like floppies (ie: no partition table)
The chip is formated with vfat I tried reformating it with ext3 but I still got the same rror (after I changed fstab)

CPUFreak91,

you might want to check this thread, if you haven't already done so:

That link could be what I'm looking for... I'll let you know if it works out ok.
