You can also build your own external USB drive, recycling a standard full-
sized drive from a desktop computer. Inexpensive external cases hold the
drive and small circuit board that converts the data interface from the direct
IDE connection used within a computer to a USB circuit. Screw the old drive
into the new holding case, attach a USB cable to the case and to the laptop,
and (alas) attach an AC adapter to give it power. I show an example of a do-it-
yourself external USB drive in Figure 7-5.
If your machine has an older USB 1.1 port, or completely lacks USB facilities,
you can add the high-speed 2.0 connection by purchasing a PC Card with that
facility. (There’s an “if” waiting here, of course: If your machine is running a
version of Windows earlier than 98SE — including Windows 98 and 95 — the
operating system will have to be upgraded to permit use of the faster USB
specification.)
PC Card attached devices .................................................................
A near-equivalent to a USB-attached hard drive is one that connects to the
laptop through a PC Card interface. The advantage to these drives is that
