Disk image !!

Hi all,
I have a SCSI hard disk drive (2GB) I'm installing on it solaris 5 and some other applications on a sun sparc workstation, I made an image file of this H.D using Norton Ghost 6, then I restored this image file on another H.D.D (4GB), I tried to boot the sun sparc workstation with this new H.D.D but it gave me the message "Bad Magic Number" !!!!!!!, what's wrong? I don't know!! The image file was created successfully and restoring the data was made successfully, the only difference is the size of the new H.D.D, so I want to boot the system normally without loosing the data using the new 4GB hard disk. Please tell me the right way to recover the system back without loses.
Note: is there a way to tell the system that the new hard disk is not 4GB and it is 2GB so that the system can recognize the disk and can boot without any error messages?
Thanks and regards
