1. Every PS3's HDD is tied specifically to the PS3 Hardware that it is originally formatted on
2. If your PS3 breaks and you attempt to put its HDD in a new PS3 it will need to format the drive to work, and you will lose all of your data
ways around this...
1. Backup your game save regularly to a flash drive, or external HDD
2. Pay the $50 per year and become a PlayStation+ member. You are given 150MB of storage for game saves on a cloud server
