Can I replace Toshba Equium A100 80 GB Hard Drive with a more powerful one?

yes.. just unscrew the cover plate underneath and slot in a new 2.5 inch drive after removing the old one, check if it sata or pata before u buy a new one.. and dont expect the system restore cd/dvd to work (changing the disk may register as not the oem hardware), so u may need to create a disk image of your old drive and restore that.
