Hi everyone! Have recently had to purchase a new harddrive for my Toshiba tecra (bought a 160GB). What I need to know is ...when I have installed it ,do I need to format it or will this be done automatically? Am a bit of a novice on these things so any help much appreciated. Also I will need to get the operating system on the new HD but do not have the XP install discs...is there anywhere I can download XP or do I need to purchase a new copy? Thanks in advance for your help. Tony.
