It's possible to buy something called an "external enclosure" for £40, into
which you can put an EIDE hard disk of your own choice (which you buy
seperately).

You need to have USB 2.0 ports on your computer. The external enclosure
plugs into one of those. Only USB 2.0 ports are fast enough to provide
anything like the data transfer speeds which you get with an internal EIDE
hard disk. The access times on a USB 1.1 port would be dreadfully slow.

In practice, many of the external enclosures on the market can only
recognise a partition not larger than 32GB. Therefore if you buy a larger
disk you must first partition it into several 32GB partitions (a 120 GB disk
will partition into 4 x 32 GB partitions).

Western Digital and other manufactuers of hard disks supply partitioning
software which you can download from the manufacturer's website, to use to
partition one of their disks.

The secret is to ensure that every partition is LESS than 32 GB (even if
only a couple of MB less), because exceeding the limit by even 1 MB will
cause the external enclosure's hardware to not recognise the disk.

There is a simpler alternative, if you have Windows XP. You can buy one of
the external 500 GB hard disks on the market, that come as a self-contained
unit and plug into a USB 2.0 port. These won't work with Windows 95/98 or
Windows ME, as those operating systems can't access a hard disk bigger than
137 GB.

The only drawback to these is a financial one: they are expensive to buy
(compared to the £40 cost of a 120 GB internal EIDE disk) - and they EAT
power! The computer will typically draw twice as many Watts, with a 500 GB
external disk attached. So watch out for your electricity bill...
