Windows 7 Imaging Issue

ok i have 2 seagate barraduas in raid 0 and i want to image my OS (which i have already done) and upgrade to WD raptors or an SSD , when i go to restore that image will  my new drives be ok because i had a maxtor 320gb hdd before and imaged it and upgraded to the hdd above and when i when to go restore my image i got an error message said that it needed thr orginal HDD (the maxtor 320gb) to complete the restore. how can a get around that or am i just doing somthing wrong
