Now you need to add up all the used space on your hard drive(s). On my Windows 98SE, I do this by highlighting each drive letter and looking over to the left hand side of the My Computer window or
right clicking on each drive letter and opening the properties box. Either way, you will find your used space in My Computer. Add the used space on all hard drives for a total amount used.
In Windows 98 it looks like this:

Find the amount of USED space in your C: drive plus any other drives listed between your A: (floppy) and CD-DVD
drives. Highlight each hard drive letter
with your mouse.

Capacity is the total size in bytes both used and free on the drive associated with the highlighted drive letter.
USED is the amount of space in bytes
used up on this drive.
Free is the amount of space in bytes that  remains available for use on this drive.
Here's how my 80Gb single hard drive is split into drives:
               CAPACITY           USED           FREE
     C:       20.6             3.07         17.5
     D:       15.6             0.771       14.9
     E:       17.7             1.79         16.0
     F:       22.1             3.93         18.2       
                                    9.561 Gb

On my 80Gb drive I'm using less than 10Gb total. What capacity drive should I use to clone this drive or combination of drives? I wouldn't use less than a 15 or 20Gb if I had a used one on hand but if I have to purchase a new drive, I wouldn't buy less than a 30Gb. Actually I don't buy less than a 40Gb these days. On the other hand, I don't need more than a 40Gb. I use my computer every day for several things and you can see how little of an 80Gb drive I've used. For cloning purposes you can use whatever size you want - larger or smaller capacity than your present drive so long as it is larger than the amount of space you've used on your current 'in service' drive(s).

Before you attempt cloning, read my warning notice located on page C1, paragraph 1.
