Laptop HD replacement

[cadmaster]

I want to replace the 4GB hard drive in my old laptop with a 20GB and transfer everything to the new drive - operating system, programs, data etc. Is this possible?
I thought a disk cloning utility would do it but the ones I've looked at all seem to require both drives to be in the same machine - the laptop only has one interface.
The only media writer the laptop has is a floppy (it does have a CD/DVD reader but that occupies the same bay as the floppy) but it does connect to my PC network. There is also a single USB port (Toughbook CF-27R).
Can I make an 'image' of the original drive on a network directory, swap the drives and restore the image to the blank disk?
The laptop runs Win98 SE (what? - I need it to run a particular program) the networked PCs run WinXP Pro and Win2k SP4.

There are two ways you can do this.

1.) Buy an external USB laptop hard drive enclosure (newegg and other suppliers have numerous examples available).

Then you can install the old drive in the enclosure and the new drive in the laptop. The cloning utility should then be able to copy one drive to the other drive. I prefer to use Norton Ghost as my cloning program of choice, but any program should work fine.

2.) Use the network share to create an image (as you said) using Ghost, etc. and then restore to the new drive.
