PS3 harddrives use standard laptop harddrives and you don't need to use a PS3 harddrive. If you want to use an old PS3 harddrive you must update the information to the new PS3 model software or it will not work
Buy a new hardrive, and replace it with the old one
buy a memory card to transfer all of the data over to the new one
i personally think that the old one is better because ps3 slim has only one fan so it over heats quickly. The old ps3 has 2 fans :)
Yes it is
well if you want to, if your old ps3 isn't working i guess you can get a new one, and don't worry, you can still have your online account if you have one.
You should not unless there is a problem: virus,broken etc. This is because the hard drive in the old one is better than the new ones
no all of your files will be lost
Yes, but so did the old one. The space required for the dashboard is minimal, and you shouldn't have to worry about it.
Amazon will give a trade in credit based on the condition and model of a PS3. It is in the form of a Gift Card and that can be used to purchase one. No one trades a new PS3 for an old one as an even trade. The trade in value is not very good at most retail stores that do take a trade ins and it is very bad when the PS3 is not working. Most places need to make a profit and have to refurbish the PS3 they take as a trade in
no my friend tried but he couldnt so you cant transfer information off your hardrive to another hardrive
Yes.
A new or used computer ... using the same operating system as the old one.
