I am trying to switch from vista to xp on an acer laptop. The laptop came installed with vista & a lot of programs that do not have upgrades to vista will not work on this machine so I have to switch back.

Unfortunately I just put in the XP disc without backing up any drivers, etc & now a lot of the drivers do not work, as well as only half of the hard drive is visible. Currently only 60 gb show up in the C:, but the hard drive in total is 120 gb.

How can I go back to XP with all of my drivers & the full capacity of the hard drive working? This has been a nightmare the past few weeks & I have not been able to use that machine. Any help would be greatly appreciated.
