ok to swap an external harddrive into a laptop?

I've just become the proud owner of a Fujitsu S6240A. Only problem is the mingy 40gb harddrive.

I also have a Lacie mobile harddrive, which I believe uses a laptop size harddrive.

<A HREF="http://www.lacie.com/products/product.htm?pid=10558" target="_new">like this, but sadly 4200rpm.</A>

I'd like to take the harddrive out of the Lacie, and swap it into the laptop. Can anyone think of any reasons why this would be a bad idea?

The process, as I imagine it:

format the external drive.
remove from external enclosure
remove internal harddrive from laptop
replace with lacie external
boot up with a boot diskette and pray it recognizes
install OS
be happy

does this seem reasonable to everyone?

thanks,

As long as it is built to take the same sort of physical stress, not all laptops are stationary objects.

Unless you need a reinstall you can use a program such as True Image 8 (my new favorite) or Ghost 9 (old favorite) to copy your os to the new drive first.

Just make sure you mount the external hard drive and remove its drive letter before booting to true image/ghost!

Otherwise there registry will remember that drive as X: and your OS will be on X: while all the references will still refer to C: !
