When you download a game, you can always delete it and re-download it at a later date.  I believe Sony allows at least 8 downloads of a purchased title.  So, don't worry about erasing a few extra titles to play a game because you can always replace the other titles.

Pretty sure you need 80GB total. 40GB for downloading and 40GB for installing.

That is correct. When you download a game you need double the space. If a game is 40GB, then you need 80GB of empty space in your HDD to download it. After you install the game you get the extra 40GB of empty space back.

That is what the Sony tech support told me. Same rule applies for backing up the system.

yes. userusb is correct.  you need double the size of a game to download it.  in this case, 80g will need to be free.

ok, well that cannot be correct.  I have an 80gig hd.  I deleted a few things, but when you look at the system info it says xx/74g.  Is some space reserved?  that would mean that it would be impossible for me to d/l and install this game.  I got up to around 55g free last night and was able to d/l and install it.

thanks for the answers.  I think that if it were the case that you need double the amount to d/l and install a game...well.........

Well, the first thing is that when a company states that you have an 80 GB HDD, they are counting a GB as being equal to 1,000 MB, a MB as being equal to 1,000 kilobytes, and a kilobyte being equal to 1,000 bytes.  That is technically incorrect as a kilobyte is equal to 1,024 bytes.  (As computers use a binary system for counting, they count kilo/mega/giga/etc. in terms of 2^10th power).  Therefore, an 80 GB (as marketed) hard drive contains 80,000,000,000 bytes in it.  As computers see it, 80 GB should be 85,899,345,920 bytes.  Since you have what is marketed as an 80GB HDD (which is legally acceptable to do since by the base-10 counting system it contains 80 billion bytes), the PS3 and any computer system out there sees it as 74.5 GB.  This is computer hardware basics 101.  Smiley Happy

 

Now with regards to the free space needed for an installation, you need to remember that the file you download is an installation file.  It needs to be unpacked in order to be reassembled into the game.  You need the extra space in order to unpack that file.  The general rule of thumb is that you need twice as much space in order to do this.  (For some games you need more than that, for some you need less). 

 

The greatest analogy for this is that your hard drive is like a room, and the items on your hard drive is like stuff you have on the floor of the room.  Let's say you went and ordered an entertainment system online (this is analagous to buying a digital game on the PSN).  This entertainment system would be delivered to you in a package from the retailer.  This package would be the equivalent of the installation file of the game you downloaded.  The entertainment center would be inside that package, just like the game is inside the installation file.  In order to build that entertainment center, you need enough free space on the floor of your room in order to build it.  If the package for the entertainment center is 2 feet by 4 feet, and the free space in your room is only 1 foot by 2 feet, how are you going to build that entertainment center? 

 

If you free up space in your room, you can build the entertainment center and then discard the packaging once it's built.  Now, the entertainment center is only taking up the space of the item itself, but you needed the extra room in order to unpack it and build it.  The same exact thing happens when you download a game.  You need the space to "unpack" the game and assemble it.  Once you've assembled it, the "packaging" (a.k.a. the installation file) is deleted freeing up that space again.  Still, you needed to have enough space to unpack it and assemble it.

 

There's nothing "wrong" about that.  It's the way things are and is only a problem when people don't take the time to understand it.  Smiley Happy
