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 can mount and umount and mount again my usb pendrive
I can mount and umount and mount again my usb hard drive
I can mount and umount and mount again my usb MP3 player
What I cannot do is mount one of them, umount them, then unplug it and plug in and mount one of the others. Once I have mounted one of them the only one that it will accept is the same device, unless I reboot.
This problem occurs whether root or user with
mount -t vfat /dev/sda1 /mnt/flash
I have this same problem on my RedHat 7.3 box, only I get no medium found instead of bad blocks. I found a workaround, but figure that the problem will go away when I have time to install a semi-recent distro on this machine.
My solution is:
Code:
<umount old drive, disconnect>
su -l
modprobe -r usb-storage
<wait ~5-10 seconds>
modprobe usb-storage
exit
<plug in new device>
mount /dev/sda1
your problem may be that the module for usb storage doesnt load at boot. what you are doing is loading the module with the modprobe command. do you use hotplugging?
I'm using REL4 with kernel version 2.6.9.
When I mount my USB using command
root@REL # mount -t vfat /dev/sda /home/usb
it raise error
"can't read supperblock"
what should I do?
