The hard disk drive platter is used to store magnetic data or information that comes from the hard disk drive, where they are stored. The hard disk drive can contain one or more hard disk platter.
No. Usually two to four.
Yes.
hard disk save data on platters. On platters there are tracks and sectors in which the data is saved.

Hard Disk Drive, Floppy Drive
A hard disk drive consists of one or more thin disks that spin at high speed (1200 to 15000 rpm) while magnetic heads read data from them, hovering extremely close to them without making contact.
A hard disk.
A computer's hard-drive.
The only way to ensure the data on the hard drive is no longer recoverable is the complete physical destruction of the drive. Superheating the platters of the drive so that they lose their magnetism is the most thorough method, though any method that makes the platters unable to be read by a read head is also effective, such as cutting with a grinder or bending with a sledgehammer.

An end user lacks the tools and expertise to successfully replace any of the hard drive platters. In addition, even if you could do it, you would likely have another problem. The platters have to be low-level formatted before they can be used, and IDE/PATA/SATA/SAS drives lack the ability to correctly format platters in this manner. So this would require special equipment.Then even if you could do all of the above, there might be differences in the metadata and firmware, and the platters still might not be compatible with the drive.
A hard disk drive (HDD), commonly referred to as a hard drive, hard disk, or fixed disk drive, is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.Source: http://en.wikipedia.org/wiki/Hard_drive
