You may upgrade your hard drive on a PS3. 160GB could be less than $100 depending on where you purchase it.
Yes PS3 uses a standard lap top hard drive and you do not even need to use one from PS3
No, you can't have 2 at once on a Ps3 but you can backup your saves and media to a memory stick or Fat32 formatted external drive and use a larger drive, for instructions go on youtube: . Or, you could just use an external Hard Disk Drive and save stuff there.
nope
It is the same as a laptop hard drive
you can delete it by transferring it to an extrenal hard drive, I believe.
No. The PlayStation 1 does not come with a hard drive, does not have an expansion bay for one, and no official add-ons provide such functionality.
Hard drive.
no they are not inchangeable
You jailbreak the firmware.
Formatting your hard disk for the PS3 will erase everything on it. If you are adding a hard disk to your PS3 it will prepare the drive for the system.
Connect to the USB port on the PS3 and see if that works. Your will not be able to download games and add ons but should be able to do music photos and videos
the hard drive crashes
