When I insert a new thumbdrive or Harddisk to my office laptop, it
will prompt me to install driver. I wonder why is it necessary to do
this for each new thumbdrive or harddisk ? Won't the drivers have
been install the first time I insert any thumbdrive or harddisk ?

Thanks.

You have to scroll down a bit to section
"You must be a member of the administrators group"...

The drivers come with XP and have a valid digital signature,
so they fulfill the 3rd requirement as long as the driver
files are intact.
The other requirements must be fulfilled by Windows. Have
you checked this? Took a look at the setupapi.log?
