If you do not use an official hard drive, you will need a WD hard drive, the Xbox hard drive sector security file and HDDhackr to partition the drive. Partition 2 must be restored manually.

After removing the drive from the old enclosure, open the new enclosure.

Put the drive in the enclosure label side up. Space may need to be added for 7mm drives.

Close the enclosure and install it in your console.
