ok so My Sata drive is failing, but i got everything i wanted and just put it on my new portable 1tb external drive but i've just got a new 1tb seagate sata drive is it possible for me to just pop that into my pc and transfer my os from the old sata to this new one or is that possible or should i just start from fresh. i cant really use the back up thing onto my external because my sata fails halfway through and the backup fails so basically what are my options? thanks in advance!
