I've been using Debian stable for years.* Now I'd like to try Debian unstable or test on* an external USB disk without modifying anything on my current disk, including partition as well as grub. Would you please give me any guides on this?* Thanks in advance.
Best regards,

You should proceed as usual (using expert installer). Installer will
detect USB disk and then you can make partitions at your wish. Just
remember to install GRUB in MBR of the USB disk.
If it fails at installing GRUB, do not worry, select "no boot loader" to
install, end Debian installation and afterwards you can install GRUB
using SGD (SuperGrubDisk).
As an alternative (and for software testing purposes) you could install a
virtual machine for Squeeze/Sid.

In theory, I guess USB driver modules should be built in Linux kernel or in* a ramdisk, otherwise kernel can not recognize USB disks, right?

I doubt the installation kernel does not come with the required USB
modules embedded :-)
JFYI:

Install Debian Lenny on USB Hard Drive

Installation should be straight forward.

I run with 2 external USB disks and have for years. Most of the time my
root partition is on an USB disk.
D-i is straight forward, just select the USB disk. Instead of grub I
prefer to run with SuperGrubDisk because that allows you to search for
the right partition and fill in what the rootdevice is. Otherwise you
are always messing around with what the disk number is. Because that
changes.
Pro: much easier to change the disk.
Con: slower than an interior disk. Except when you can use the SATA
cable on the exterior disk, but I have trouble with my mobo on that.

I've successfully installed Debian Squeeze on an external USB disk.* At first grub was incorrectly installed on the internal disk, which caused the system unbootalbe.* Then I used the install disk as a rescue and fixed the issue.* Thank you all!
