anybody can help me?
Tks!

Do you want to boot from it or are you planning only to keep data in it?

only put data from it!

Insert your USB drive and run dmesg. You should see it toward the bottom as some thing like /dev/sda1 or maybe sdb1, if you have a SATA hard drive. Then what I do is

mkdir /mnt/usb

to create a mount point or just reuse /mnt/floppy on machines that don't have a real floppy. After all that's what USB drives are for now.

Then edit /etc/fstab and add a line like this

/dev/sda1 /mnt/usb auto noauto,users 0, 0

Again you can just reuse the /mnt/floppy entry and change /dev/floppy to your actual device.

Now you can mount your USB drive with this command

mount /mnt/usb

or

mount /mnt/floppy

unmount with

umount /mnt/usb

or

umount /mnt/floppy

Dennisk

I test if I don't stat /etc/rc.hotplug ,use the dmesg can't see the usb disk.(sda)
use usb disk must start the rc.hotplug???
