Okay so I am going to be buying a 500GB momentus XT to replace my current 500GB HDD in my Acer 3820TG. However my currency HDD is partitioned into 3 parts (recovery 10GB, windows 90GB, other junk 362GB). I want to clone EVERYTHING onto the new HDD and basically just switch them out. Is it possible to just clone HDD? I have these wires that connect into SATA ports and then to USB so i was wondering if i can use those? Would it work if I just backup my entire system on an external HDD and then use system restore? I want to keep all the partitions and all the files. thanks.
