when i mount my USB Flash Drive A Messenge has come that mount: can't find /dev/sda/home/usb in /etc/fstab or /tetc/mtab please any one help me to sol this problem i am new user of Linux.

Strange place to mount a USB drive!... or did you forget a space?

So: /dev/sda <space> /home/usb

The general convention is to mount uncer /mnt (although Fedora would mount under /media). Anyway, mounting a usb device is like mounting a partition and you do not indicate a partition number (like /dev/sda1).

Also, unless you added a line to fstab with the mount instructions the command '# mount /home/usb' wouldn't know what to do.

What command did you use to mount?
Have you added a line to fstab?
less important, but still, what distro do you use?

edit:just realised you posted in the RedHat forum. But since I found your post through the 0 reply option it wasn't all that clear. Maybe you could include your distro in your profile so it'll show up under your user name.
