Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I installed slackware 9.0 on a system and it won't mount the USB stick. It did on other PC's... When trying to mount (as root) it says: "/dev/sda1 is not a valid block device". however, ls -al /dev/sda1 tells me: "brw-r----- 1 root disk 8, 1 1995-04-29 09:33 sda1", the 'b' means block device?

edit: I tried other possible devices too, like sda2 or sdb1 etc etc, all same problem...
Yeah. Like the guy above said, did you make a USB mount point in /etc/fstab? It's ok if you did not, you will just have to specify when you mount it. Like 'mount /dev/sda1 /mnt' then just change to /mnt and do whatever you want. then umount it
As valid as the previous two replys are, I believe that they are discussing the wrong problem. It is true that an entry in /etc/fstab would be needed for implicit mounting, however, when an error message such as the one quoted by the OP occurs, it isn't because of an fstab problem - it's usually a driver issue. When mount looks at a 'device' and tries to mount it, it needs to verify that it is, in fact, mountable. The error that the OP mentioned occurs when mount says, 'Uh oh, I can't mount that one...'. _Typically_ this is a problem with drivers ( Department of Redundancy Department ).
I looked at the /var/log/messages and it says something like "no module for usb device". Maybe it's 'cause I compiled a custom kernel (needed for video driver) and I forgot something to compile...? what options are exactly needed then?
