it is for installing cracked 'cheep' games to ps3's hard drive
No, games need to be installed locally onto the hard drive of the computer you wish to play it from.
install to hard drive still requires a disk. the point of installing it is that your xbox will be quiet when your playing the game on it. it also makes the game load faster.
No.
No it does not. As long as the motherboard has the proper connectors for the hard drive you are installing, IDE or SATA, you will not have to replace it. If the connectors are different, then return the hard drive and get one with the proper connection type.
This is to prevent people from renting games and installing them on their harddrive.
operating system
the hard drive should be set to master...
I would suggest installing windows on one hard drive, then installing ubuntu on the same hard drive. Use the other hard drive for the backups (partition it).
No, the only benifet of installing it onto the hard drive is presemably shorter loading times for the games. But for the majority of games it only affects it by seconds, if at all. The game disk is still required for gameplay.
Installing the program to your hard drive
No, you just need the hard drive itself to install them, but I wouldn't recommend installing games to your hard drive unless: A. You are getting another xbox, and want to transfer your data or B. You have space to spare. or..................... C. your parents took away u games.......
