USB booting :: mounting /dev/sda2



Ok, so I have to finally post a question to the forum.  I have a lexar 256 jump drive.  DSL is up and running from booting off the usb drive.  Everything works wonderfully , but I can't get the second partition to mount after booting.

If I put the drive in my Suse box, and can mount it and write to it just fine.  But, under DSL, a mount attempt just results in an invalid block device error.

I'm thinking I'm booting with the wrong parameters, or mounting improperly for dsl.  

mount /dev/sda2 /mnt is what I've been using.  Like I said, it works under my other linux box.

Any suggestions on what to try?  I've tried a bunch of things, like specifying the fs type, and mounting it somewhere else.  Nothing seems to work.

Thanks,
dewman

from my suse box...

I forgot to mention, I formatted the /dev/sda2 partition as ext2.

:D
Here is the dmesg from within dsl.  I would belive it if I hadn't been able to get it to mount and work on suse.

Also, some attempts to show the geometry in dsl, as well as a df -k.

It also let's me get into /mnt, and sda2, but it shows it is mounted on /  I don't understand this.
