thats cute! nice find though
Personally I would perform a clean install of the operating system / the benefits of better performance will be worth the time invested
and OS gets VERY luggish after about two years
you could then put your old drive with all its contents into a 2.5 inch external hard drive enclosure or get a 2.5 inch adapter which will allow you to connect your old 55 gig to a desktop machine / from there you can share the data with the laptop
your call ?
