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.

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.
