hi im new to the mac world and ive just got my first mbp, i got a crucial m4 ssd and thought id give it an upgrade so i used carbon copy to clone but now all i get is the question mark flashing even when i put the original hdd back in. i did notice which i cant understand why is that if i plug the ssd or the original hdd in via usb it boots up but if i connect them inside the mac it gives question mark. ive tried to install new system but fails to see any device to install on, but as ive said if i connect using usb it see it????? Totally lost here guys. just hope this can be fixed some how. any ideas. Thanks ---------- oh and when i try to erase the drive via usb it fails on last block ??
