Hi there i used to have a dell xps 710 but the motherboard failed , and dell could not repair it so i was offered a new machine which i have just recieved which is running on windows 7. Now i purchased my old hard drives from the xps from dell and want to put them into the new machine so i can access the data movies , music etc but am having problems when i put them in new machine the drive showed up but said i had to format it first before use , dont want to do that or will lose all data can anyone help they were set up as raid o on the xps machine so two drives but really just one oh and running on vista where as the new machine is windows 7 do i need to change something in bios or something ?.... thanks Sean
