not really use this software (easeus.com/disk-copy/) is via msdos by a pendrive
1) 01 Pendrive empty (just 1Gb)
2) Cases of 02 HD SATA (USB HD will receive a case of old PS3, the other new HD)
3) 01 free program called EASE U.S. DISK COPY:
1) Download the program mentioned above, EASEUS (45MB) and run no need to install;
2) Plug in the USB pendrive empty;
3) Turn the EASUS and let it format the pendrive, it will become a boot disk. Leave the stick stuck there.
4) After you format the USB stick just right, TURN OFF THE PC = this step is important to prevent the operating system attempts to read or write to the PS3's hard drive and thus you lose all your data encrypted by the PS3;
5) TAKE TURN THE PS3. Only then remove the old HD PS3 careful not to strip any screws;
6) Prepare the first case SATA: put the old HD from the PS3 and plug in a USB in the pc;
7) Prepare the second case SATA: put the new HD that will for the PS3 and plug in another USB in the pc;
8) Turn on your PC on and choose to boot the USB disk with EASEUS;
9) When thepc starts EASEUS within the program, choose DISK COPY. This is the option that copies the old to the new HD, 1:1, byte by byte;
10) Choose SOURCE as the old PS3's HD, which will be depending on your PS3 40gb or 80, 120, 160, 320 ... Mine was 80GB;
11) Choose the HD DESTINY as the new PS3, which will be the size of the new HD that you chose. Mine was 250GB;
12) Pay attention to both disks appear as "unmounted" due to the file system and encrypted crazy PS3, but can proceed without fear;
13) Depending on the size of your hard drives copying may take between 1am and 6am. Here, 80GB -> 250GB took 1:30 h, so my notebook is lentinho pq;
14) When finished cloning the new HD will be automatically resized to its maximum size, ie the PS3 with HD had seen the new size as if he had never left in the game;
15) Turn it OFF the pc when it's over and remove the cases of the USB ports.
16) Remove the new HD's case, reassemble it on the PS3, keep calm w / not doing things and running into problems, poor little pravc test if it worked!
17) After all certinho mounted on the PS3, then turn it on and boot making.
18) surprise, everything keeps working the way it was, except that increased disk space!
