Slack 10.1 can't mount usb thumb drive

[Frank Kumro]

I just installed slackware 10.1 (removing FC3) and currently its
running the 2.4 kernel (ugh). When I try to mount my usb thumb drive i
get the below error. I remember very clear that this did work on FC3
and FC used the 2.6 kernel. Is there a different way to mount in 2.4
kernel? I also tried sda and sda1-xx. All returned the following
error. Yes the disk is formatted for use on both windoze and linux and
there are files on it. Any help would be great!

bash-3.00$ sudo mount /dev/sda1 /mnt/usb/
mount: /dev/sda1 is not a valid block device
